1 The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool. 2 The LORD shall send the rod of thy strength out of Zion: rule thou in the midst of thine enemies. 3 Thy people shall be willing in the day of thy power, in the beauties of holiness from the womb of the morning: thou hast the dew of thy youth. 4 The LORD hath sworn, and will not repent, Thou art a priest for ever after the order of Melchizedek. 5 The Lord at thy right hand shall strike through kings in the day of his wrath. 6 He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries. 7 He shall drink of the brook in the way: therefore shall he lift up the head.

[AD 60] Mark on Psalms 110:1
And Jesus answered and said, while he taught in the temple, How say the scribes that Christ is the Son of David? For David himself said by the Holy Ghost, The Lord said to my Lord, Sit thou on my right hand, till I make thine enemies thy footstool. [Psalms 110:1] David therefore himself calleth him Lord; and whence is he then his son? And the common people heard him gladly.
[AD 60] Matthew on Psalms 110:1
While the Pharisees were gathered together, Jesus asked them, Saying, What think ye of Christ? whose son is he? They say unto him, The Son of David. He saith unto them, How then doth David in spirit call him Lord, saying, The LORD said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool? [Psalms 110:1] If David then call him Lord, how is he his son? And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.
[AD 61] Luke on Psalms 110:1
And he said unto them, How say they that Christ is David's son? And David himself saith in the book of Psalms, The LORD said unto my Lord, Sit thou on my right hand, Till I make thine enemies thy footstool. [Psalms 110:1] David therefore calleth him Lord, how is he then his son?
[AD 62] Acts on Psalms 110:1
Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand, Until I make thy foes thy footstool. [Psalms 110:1] Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
[AD 69] Hebrews on Psalms 110:1
For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son? And again, when he bringeth in the firstbegotten into the world, he saith, And let all the angels of God worship him. And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire. But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom. Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows. And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands: They shall perish; but thou remainest; and they all shall wax old as doth a garment; And as a vesture shalt thou fold them up, and they shall be changed: but thou art the same, and thy years shall not fail. But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool? [Psalms 110:1] Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
[AD 132] Epistle of Barnabas on Psalms 110:1
Observe again that it is Jesus, not a son of a man but the Son of God, and revealed in the flesh by a symbol.Since, however, they were going to say that the Messiah is the son of David, David himself, fearing and understanding the error of sinners, prophesied, “The Lord said to my Lord, ‘Sit at my right hand until I make your enemies a footstool for your feet.’ ” And again, Isaiah says as follows: “The Lord said to the Messiah my Lord, whose right hand I held, that the nations would obey him, and I will shatter the strength of kings.” Observe how David calls him “Lord” and does not call him “son.”

If, sirs, it were not said by the Scriptures which I have already quoted, that His form was inglorious, and His generation not declared, and that for His death the rich would suffer death, and with His stripes we should be healed, and that He would be led away like a sheep; and if I had not explained that there would be two advents of His — one in which He was pierced by you; a second, when you shall know Him whom you have pierced, and your tribes shall mourn, each tribe by itself, the women apart, and the men apart — then I must have been speaking dubious and obscure things. But now, by means of the contents of those Scriptures esteemed holy and prophetic among you, I attempt to prove all [that I have adduced], in the hope that some one of you may be found to be of that remnant which has been left by the grace of the Lord of Sabaoth for the eternal salvation. In order, therefore, that the matter inquired into may be plainer to you, I will mention to you other words also spoken by the blessed David, from which you will perceive that the Lord is called the Christ by the Holy Spirit of prophecy; and that the Lord, the Father of all, has brought Him again from the earth, setting Him at His own right hand, until He makes His enemies His footstool; which indeed happens from the time that our Lord Jesus Christ ascended to heaven, after He rose again from the dead, the times now running on to their consummation; and he whom Daniel foretells would have dominion for a time, and times, and an half, is even already at the door, about to speak blasphemous and daring things against the Most High. But you, being ignorant of how long he will have dominion, hold another opinion.

That God the Father of the universe would bring Christ to heaven after his resurrection from the dead and would keep him there until he destroyed his enemies, the demons, and until the quota of those whom he foreknows to be good and virtuous was complete, because of whom he has always delayed the consummation of the world, listen to the words spoken through David the prophet: “The Lord said to my Lord: ‘Sit at my right hand, until I make your enemies your footstool.’ The Lord shall send to you the scepter of power out of Jerusalem; and rule you in the midst of your enemies. With you is the government in the day of your power, in the brightness of your saints. From the womb have I begotten you before the morning star.” The words “he shall send to you the scepter of power out of Jerusalem” signified the powerful teaching that the apostles, going out from Jerusalem, preached everywhere. And although those who teach, or even profess, the name of Christ, will be martyred, we everywhere both accept and teach it. But, if you also should read these words with hostile mind, you can do nothing more, as we already stated, than kill us, which does no real harm to us, but does bring the eternal punishment of fire to you and to all who unjustly hate and do not repent.

[AD 165] Justin Martyr on Psalms 110:1
For instance, your teachers have presumed to refer the words, “The Lord said, to my Lord: Sit at my right hand, till I make your enemies your footstool,” to Hezekiah as if he were ordered to sit on the right side of the temple, when the Assyrian king sent men to him with menacing messages and he was warned by Isaiah not to be afraid. Now, we all know and acknowledge that what Isaiah predicted did actually happen, and that in the days of Hezekiah the Assyrian king was stopped from waging war on Jerusalem and that an angel of the Lord put to death about 185, in the Assyrian camp. But, it is evident that the quoted psalm does not refer to Hezekiah, for thus is it worded: “The Lord said to my Lord: Sit at my right hand, till I make your enemies your footstool. He shall send forth the scepter of power on Jerusalem, and he shall rule in the midst of your enemies. In the brightness of the saints, before the morning star I begat you. The Lord has sworn, and he will not repent: You are a priest forever according to the order of Melchizedek.” Now, who will not concede that Hezekiah was not a priest forever according to the order of Melchizedek? And who is not aware that he was not the redeemer of Jerusalem? And who does not know that he did not send the scepter of power on Jerusalem and did not rule in the midst of his enemies? (For was it not God who turned his enemies away while he wept and moaned?) But, although our Jesus has not yet returned in glory, he has sent forth into Jerusalem the scepter of power, namely, the call to repentance to all the nations over which the demons used to rule, as David testifies: “The gods of the Gentiles are demons.” And the power of his word compelled many to abandon the demons whom they used to obey and through him to believe in almighty God, because the gods of the Gentiles are demons. Furthermore, we have proved earlier that the words, “In the brightness of the saints, from the womb before the morning star I begot you,” were addressed to Christ!

1. He who delivered from the lowest hell the man first made of earth, when lost and bound by the chains of death; He who came down from above, and exalted earth-born man on high; He who is become the preacher of the Gospel to the dead, the redeemer of souls, and the resurrection of the buried;-He became the helper of man in his defeat, and appeared in his likeness, the first-born Word, and took upon Himself the first Adam in the Virgin; and though spiritual Himself, He made acquaintance with the earthy in the womb; though Himself the ever-living One, He made acquaintance with the dead in transgressions; Himself the heavenly One, He bore the terrestrial on high; Himself of lofty extraction, He chose, by His own subjection, to set the slave free; and making man, who turns to dust, and forms food for the serpent, unconquerable as adamant, and that, too, when hung upon the tree, He declared him lord over his victor, and is thus Himself proved conqueror by the tree.

2. Those, indeed, who do not acknowledge the incarnate Son of God now, shall have to acknowledge Him as Judge, when He who is now despised in His inglorious body, comes in His glory.

3. And when the apostles came to the sepulchre on the third day, they did not find the body of Jesus; just as the children of Israel went up the mount to seek the tomb of Moses, and did not find it.

He [Christ] foretells that he would rise again from the dead: “And in that day there shall be a root of Jesse and one who shall rise to rule the Gentiles: in me shall the Gentiles hope, and his resting place shall be worthy of honor.” The time of his resurrection is indicated: “We shall find him ready, as it were, at daybreak.” He shall sit at the right hand of the Father: “The Lord says to my Lord, ‘Sit at my right hand till I make your enemies your footstool,’ ” and he is represented as the possessor of all things: “Ask of me, and I will give you the nations for your inheritance and the ends of the earth for your possession.” Finally, he is shown to be the Judge of all: “O God, give the King your judgment, and your justice to the king’s son.” I shall not pursue the matter further at this point; for the things proclaimed about Christ are known to all heretics and are more than familiar to those who hold the truth.

[AD 373] Athanasius of Alexandria on Psalms 110:1
God, when “becoming a God and a defense” and saying, “I will be a God to them,” does not then become God more than before, nor does he then begin to become God. Rather, what he had always been, that he then becomes to those who need him, when it pleases him. So Christ, also being by nature Lord and King everlasting, does not become Lord more than he was at the time he is sent forth, nor does he then begin to be Lord and King but what he has always been, that he then is made according to the flesh. Having redeemed all, he thereby becomes again Lord of the living and the dead. Thereafter everything serves him, and this is David’s meaning in the psalm, “The Lord said to my Lord, ‘Sit on my right hand, until I make your enemies your footstool.’ ” For it was fitting that the redemption should take place through none other than him who is the Lord by nature, lest, though created by the Son, we should name another Lord, and fall into the Arian and Greek folly of serving the creature beyond the all-creating God.

If then they suppose that the Savior was not Lord and King, even before he became man and endured the cross, but then began to be Lord, let them know that they are openly reviving the statements of the Samosatene. But if, as we have quoted and declared above, he is the everlasting Lord and King, seeing that Abraham worships him as Lord and Moses says, “Then the Lord rained on Sodom and on Gomorrah brimstone and fire from the Lord out of heaven”; and David in the Psalms, “The Lord said to my Lord, ‘Sit on my right hand’ ”; and “Your throne, O God, is forever and ever; a scepter of righteousness is the scepter of your kingdom”; and “Your kingdom is an everlasting kingdom”;18 it is plain that even before he became man, he was King and Lord everlasting, being Image and Word of the Father. And since the Word is everlasting Lord and King, it is very clear again that Peter did not say that the essence of the Son was made but spoke of his lordship over us, which “became” when he became man, and redeeming all by the cross, became Lord of all and King.

So let us not be ashamed of the cross of Christ, but even if someone else keeps it secret, you should openly sign it upon your forehead, so that evil spirits beholding the royal symbol may fly far from you, terrified. Make this sign as you eat and drink, when you sit down, when you go to bed, when you get up again, while you are talking, while you are walking, in brief, at your every undertaking. He who was crucified then is now in heaven above. For we would have cause to be ashamed if, after he had been crucified and buried, he had remained in the grave. But now, he who was crucified on this very Golgotha ascended to heaven from the Mount of Olives there to the east. For from there he went down into hell and came again to us here. Again he went up from us into heaven, when the Father called him saying, “Sit on my right hand, until I make your enemies your footstool.”

If reasoning does not move you, at least let the plain aspect of the judgment move you! Raise your eyes to the Judge, see who it is that is seated, with whom he is seated, and where. Christ is sitting at the right hand of the Father. If you cannot perceive this with your eyes, hear the words of the prophet: “The Lord said to my Lord, ‘Sit on my right hand.’ ” The Son, therefore, sits at the right hand of the Father. Tell me now, you who hold that the things of God are to be judged as the things of this world are judged, whether you think that he who sits at the right hand is lower? Is it any dishonor to the Father that he sits at the Son’s left hand? The Father honors the Son, and you make it to be an insult! The Father would have this invitation to be a sign of love and esteem, and you would make it an overlord’s command! Christ has risen from the dead and sits at the right hand of God.

"The Lord said unto my Lord, Sit on My right hand, until I make Your enemies Your footstool" [Psalm 110:1]. We ought, therefore, thoroughly to consider this question proposed to the Jews by the Lord, in the very commencement of the Psalm. For if what the .Jews answered be asked of us, whether we confess or deny it; God forbid that we should deny it. If it be said to us, Is Christ the Son of David, or not? If we reply, No, we contradict the Gospel for the Gospel of St. Matthew thus begins, "The book of the generation of Jesus Christ, the Son of David." [Matthew 1:1] The Evangelist declares, that he is writing the book of the generation of Jesus Christ, the Son of David. The Jews, then, when questioned by Christ, whose Son they believed Christ to be, rightly answered, the Son of David. The Gospel agrees with their answer. Not only the suspicion of the Jews, but the faith of Christians, does declare this...."If then David in the spirit called Him Lord, how is He his son?" The Jews were silent at this question: they found no further reply: yet they did not seek Him as the Lord, for they did not acknowledge Him to be Himself that Son of David. But let us, brethren, both believe and declare: for, "with the heart we believe unto righteousness: but with the mouth confession is made unto salvation;" [Romans 10:10] let us believe, I say, and let us declare both the Son of David, and the Lord of David. Let us not be ashamed of the Son of David, lest we find the Lord of David angry with us.

But Christ the Lord does all these things in us. Before he returned to heaven, he promised his disciples and said, “But when I ascend, I will ask my Father and he will send you another Paraclete, who will be with you forever, the Spirit of truth.” Thus, we must believe that Christ went to the Father when we see that the Paraclete came down upon the apostles. We must believe, I say, (as David said about the Savior) that he sat down at the right hand of God, because we discern that the Holy Spirit moves freely among the disciples, just as the Lord promised. Therefore the prophetic psalm says, “The Lord said to my Lord, ‘Sit at my right hand.’ ” In our custom a person is offered a seat when he has accomplished some task and comes as a victor and the favor of a seat of honor is offered to him. Thus, in the same way the man Jesus Christ also conquered the devil by his suffering, harrowed hell by his resurrection, came to heaven as a victor once his work was done, and heard from God the Father, “Sit at my right hand.” Nor is it astonishing if the Father offers the Son the right to sit on one seat with him, since he is by nature of one substance with the Father. But someone may be prompted to ask why the Son is said to sit at his right hand. Although there is no degree of worthiness wherever there is a fullness of divinity, nonetheless, the Son sits at the right hand not so that he may be held higher than the Father, but so that he may not be believed to be inferior. And so the Son sits at the right hand because in the gospel the sheep are stationed at the right hand while the goats are on the left.

And what follows? "The Lord shall send the rod of Your power out of Sion" [Psalm 110:2]. It appears, brethren, it most clearly appears, that the Prophet is not speaking of that kingdom of Christ, in which He reigns for ever with His Father, Ruler of the things which are made through Him: for when does not God the Word reign, who is in the beginning with God? [John 1:1] For it is said, "Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever." [1 Timothy 1:17] To what eternal King? To one invisible, incorruptible. For in this, that Christ is with the Father, invisible and incorruptible, because He is His Word, and His Power, and His Wisdom, and God with God, through whom all things were made; He is "King eternal;" but, nevertheless, that reign of temporal government, by which, through the mediation of His flesh, He called us into eternity, begins with Christians; but of His reign there shall be no end. His enemies therefore are made His footstool, while He is sitting on the right hand of His Father, as it is written; this is now going on, this will go on unto the end....

[AD 328] Alexander of Alexandria on Psalms 110:3-4
And Paul has declared his [Christ’s] proper and peculiar, natural and excellent sonship when he thus says of God: “Who spared not his own Son, but for us,” who were not his natural sons, “delivered him up.” For to distinguish him from those who are not properly sons, he said that he was his own Son. And in the Gospel we read, “This is my beloved Son, in whom I am well pleased.” Moreover, in the Psalms the Savior says, “The Lord has said to me, You are my Son.” Where, showing that he is the true and genuine Son, he signifies that there are no other genuine sons besides himself. And what, too, is the meaning of this: “From the womb before the morning I begat you”? Does he not plainly indicate the natural sonship of paternal begetting, which he obtained not by the careful framing of his manners, not by the exercise of and increase in virtue, but by property of nature? Wherefore, the only-begotten Son of the Father, indeed, possesses a flawless sonship; but the adoption of rational sons belongs not to them by nature but is prepared for them by the uprightness of their life and by the free gift of God. And it [human nature] is mutable, as Scripture recognizes: “For when the sons of God saw the daughters of men, they took for themselves wives,” etc. And in another place: “I have nourished and brought up children, but they have rebelled against me,” as we find God speaking by the prophet Isaiah.

And what follows in the psalm would agree with him alone, where it says, “The Lord said to me, You are my Son. Today have I begotten you. Ask of me, and I will give you the heathen for your inheritance and the utmost parts of the earth for your possession.” For surely only in him has this part of the prophecy received an indubitable fulfillment, since the voice of his disciples has gone forth into all the earth and their words to the ends of the world. And the passage distinctly names Christ, saying as in his own person, that he is the Son of God, when it says, “The Lord said to me, You are my Son. Today I have begotten you.” With which you may compare the words in the Proverbs, also spoken in his own person: “Before the mountains were established, before all the hills he brings me forth.” And also the address by the Father to him in Psalm 109 [LXX]: “I begat you from my womb before the morning star.” Understand then how the holy Scriptures prophesy that one and the same being, Christ by name, who is also Son of God, is to be plotted against by people, to receive the nations for his inheritance and to rule over the ends of the earth, showing his dispensation among people by two proofs: the one being the attacks on him and the other the subjection of the nations to him.

[AD 367] Hilary of Poitiers on Psalms 110:3-4
Meanwhile, I ask each one’s opinion about the interpretation of “from him.” Are we to understand these words in the sense of coming from another person, or from no one else, or are we to believe that he himself was the one to whom he was referring? They are not from another person, because they are “from him,” that is, in the sense that God does not come from anywhere else except than from God. They are not from nothing, because they come “from him,” for a nature is revealed from which the birth is derived. He himself is not meant, because “from him” refers to the birth of the Son from the Father. Moreover, when it is pointed out that he is “from the womb,” I ask whether it is possible to believe that he was born from nothing, since the true nature of the birth is revealed by applying the terminology of bodily functions? God was not composed of bodily members when he spoke of the generation of the Son in these words: “From the womb before the day star I begot you.” He spoke in order to enlighten our understanding while he confirmed that ineffable birth of the only-begotten Son from himself with the true nature of the godhead, in order that he might impart to the faculties of our human nature the knowledge of the faith concerning his divine attributes in a manner adapted to our human nature, in order that he might teach us by the expression “from the womb” that the existence of his Only-Begotten was not a creation from nothing but a natural birth from himself. Finally, has he left us in any doubt whatsoever that his words “I came forth from the Father and have come” are to be understood in the sense that he is God, that his being does not come from anywhere else except from the Father? When he came forth from the Father, he did not have a different nature or no nature, but he bears testimony to the fact that he is his author from whom, as he says, he has gone forth.

[AD 373] Athanasius of Alexandria on Psalms 110:3-4
But since there are poorly instructed people who, while resisting the doctrine of a Son, think little of the words “from the womb before the morning star I begat you,” as if this referred to his relation to Mary, alleging that he was born of Mary “before the morning star.” Since to say that “womb” could not refer to his relation toward God, we must address the issue briefly here. If then, because the “womb” is human, therefore it is foreign to God; “heart” too clearly has a human meaning, for that which has heart has womb also. Since then both are human, we must deny both or seek to explain both. Now as a word is from the heart, so is an offspring from the womb; and as when the heart of God is spoken of, we do not conceive of it as human, so if Scripture says “from the womb,” we must not understand it in a corporeal sense. For it is usual with divine Scripture to speak and signify in the way of humankind what is above humankind. Thus speaking of the creation it says, “your hands made me and fashioned me,” and, “your hand made all these things,” and, “he commanded, and they were created.” Scripture’s language is suitable then about everything; attributing to the Son “propriety” and “genuineness” and to the creation “the beginning of being.” For the one God makes and creates, but him [the Son] he begets from himself, Word or Wisdom. Now “womb” and “heart” plainly declare what is proper and the genuine, for we too have this from the womb, but our works we made by our hands.

Plainly, divine Scripture, which knows better than any the nature of everything, says through Moses, of the creatures, “In the beginning God created the heaven and the earth”; but of the Son it introduces not another but the Father himself saying, “I have begotten you from the womb before the morning star”; and again, “You are my Son, this day have I begotten you.” And the Lord says of himself in Proverbs, “Before all the hills he begets me”; and concerning things originated and created John says, “All things were made by him”;50 but speaking of the Lord, he says, “The only-begotten Son, who is in the bosom of the Father, he declared him.” If then he is a son, therefore he is not a creature; if a creature, his is not a son; for the difference between them is great, and son and creature cannot be the same, unless his essence is considered to be at once from God and external to God.

Again, immediately before the declaration “the Lord created me,” he says, “I will tell of the things that are from eternity,” and before saying, “he begat,” he said, “In the beginning, before he made the earth, before all hills.” In its extent, the preposition “before” reaches back into the past without end or limit, and so “Before Abraham was, I am,” clearly need not mean “after Adam,” just as “before the morning star” need not mean “after the angels.” But when he said “before,” he intended not that he was included in anyone’s existence but that all things are included in his, for thus it is the custom of holy Scripture to show the eternity of God. Finally, in another passage you may read, “Before the mountains were brought forth, or ever the earth and the world were made, you are from everlasting to everlasting.”58Before all created things, then, the Son is begotten; within all and for the good of all is he made; begotten of the Father, above the law, brought forth of Mary, under the law.

Whence also the prophet says, The Lord has sworn, and will not repent: “You are a priest forever, after the order of Melchizedek.” Christ became a priest on the cross, when he offered the whole burnt offering of his own body and blood as a sacrifice for all the world.

[AD 69] Hebrews on Psalms 110:4
If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? For the priesthood being changed, there is made of necessity a change also of the law. For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar. For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood. And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, Who is made, not after the law of a carnal commandment, but after the power of an endless life. For he testifieth, Thou art a priest for ever after the order of Melchisedec. For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God. And inasmuch as not without an oath he was made priest: (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec) [Psalms 110:4] By so much was Jesus made a surety of a better testament. And they truly were many priests, because they were not suffered to continue by reason of death: But this man, because he continueth ever, hath an unchangeable priesthood. Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them. For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself. For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
[AD 430] Augustine of Hippo on Psalms 110:4
And unto what are You born? "The Lord has sworn, and will not repent: You are a Priest for ever after the order of Melchizedec" [Psalm 110:4]. For unto this were You born from the womb before the morning star, that You might be a Priest for ever after the order of Melchizedec. For in that character in which He was born of the Father, God with God, coeternal with Him who begot Him, He is not a Priest; but He is a Priest on account of the flesh which He assumed, on account of the victim which He was to offer for us received from us. "The Lord," then, "has sworn." What then means, the Lord has sworn? Does the Lord, who forbids men to swear, [Matthew 5:34] Himself swear? Or does He possibly forbid man to swear chiefly on this account, that he may not fall into perjury, and for this reason the Lord may swear, since He cannot be forsworn. For man, who, through a habit of swearing, may slip into perjury, is rightly forbidden to swear: for he will be farther from perjury in proportion as he is far from swearing. For the man who swears, may swear truly or falsely: but he who swears not, cannot swear falsely; for he swears not at all. Why then should not the Lord swear, since the Lord's oath is the seal of the promise? Let Him swear by all means. What then do you, when you swear? You call God to witness: this is to swear, to call God to witness; and for this reason there must be anxiety, that you may not call God to witness anything false. If therefore thou by an oath dost call God to witness, why then should not God also call Himself to witness with an oath? "I live, says the Lord," this is the Lord's oath...."The Lord swore," then, that is, confirmed: "He will not repent," He will not change. What? You are a Priest for ever. "For ever," for He will not repent. But Priest, in what sense? Will there be those victims, victims offered by the Patriarchs, altars of blood, and tabernacle, and those sacred emblems of the Old Covenant? God forbid! These things are already abolished; the temple being destroyed, that priesthood taken away, their victim and their sacrifice having alike disappeared, not even the Jews have these things. They see that the priesthood after the order of Aaron has already perished, and they do not recognise the Priesthood after the order of Melchizedec. I speak unto believers. If catechumens understand not something, let them lay aside sloth, and hasten unto knowledge. It is not therefore needful for me to disclose mysteries here: let the Scriptures intimate to you what is the Priesthood after the order of Melchizedec.

"The Lord on Your right hand" [Psalm 110:5]. The Lord had said, "Sit on My right hand;" now the Lord is on His right hand, as if they changed seats....That very Christ, the "Lord on Your right hand," unto whom You have sworn, and it will not repent You: what does He, Priest for evermore? What does He, who is at the right hand of God, and intercedes for us, [Romans 8:34] like a priest entering into the inner places, and into the holy of holies, into the mysteries of heaven, He alone being without sin, and therefore easily purifying from sins. He therefore "on Your right hand shall wound even kings in the day of His wrath." What kings, do you ask? Have you forgotten? "The kings of the earth stood up, and the rulers took counsel together against the Lord, and against His Anointed." These kings He wounded by His glory, and by the weight of His Name made kings weak, so that they had not power to effect what they wished. For they strove amain to blot out the Christian name from the earth, and could not; for "Whosoever shall fall on this stone shall be broken." [Matthew 21:44] Kings therefore fall on this "stone of offense," and are therefore wounded, when they say, Who is Christ? I know not what Jew or what Galilean He may have been, who died, who was slain in such a manner! The stone is before your feet, lying, so to speak, mean and humble: therefore by scorning thou dost stumble, by stumbling you fall, by falling you are wounded...."But on whomsoever it shall fall, it will grind him to powder." [Luke 20:18] When therefore any one falls upon it, it lies as it were low; it then wounds: but when it shall grind him to powder, then it will come from above. See how in these two words, it shall wound him and grind him to powder: he strikes upon it, and it shall come down upon him: are distinguished the two seasons, of the humiliation and the majesty of Christ, of hidden punishment and future judgment. He will not crush, when He comes, that man whom He does not wound when He lies in a contemptible appearance....

"He shall judge among the heathen: He shall fill up what has fallen" [Psalm 110:6]. Whoever you are who art obstinate against Christ, you have raised on high a tower that must fall. It is good that you should cast yourself down, become humble, throw yourself at the feet of Him who sits on the right hand of the Father, that in you a ruin may be made to be built up. For if you abide in your evil height, you shall be cast down when you can not be built up. For of such the Scripture says in another passage: "Therefore shall He break down, and not build them up." Beyond doubt he would not say this of some, unless there were some whom He broke down so as to build them up again. And this is going on at this time, while Christ is judging among the heathen in such a manner as to fill up what has fallen. "He shall smite many heads over the earth." Here upon the earth in this life He shall smite many heads. He makes them humble instead of proud; and I dare to say, my brethren, that it is more profitable to walk here humbly with the head wounded, than with the head erect to fall into the judgment of eternal death. He will smite many heads when he causes them to fall, but He will fill them up and build them up again.

"He shall drink of the brook in the way, therefore shall he lift up his head" [Psalm 110:7]. Let us consider Him drinking of the brook in the way: first of all, what is the brook? The onward flow of human mortality: for as a brook is gathered together by the rain, overflows, roars, runs, and by running runs down, that is, finishes its course; so is all this course of mortality. Men are born, they live, they die, and when some die others are born, and when they die others are born, they succeed, they flock together, they depart and will not remain. What is held fast here? What does not run? What is not on its way to the abyss as if it was gathered together from rain? For as a river suddenly drawn together from rain from the drops of showers runs into the sea, and is seen no more, nor was it seen before it was collected from the rain; so this hidden rain is collected together from hidden sources, and flows on; at death again it travels where it is hidden: this intermediate state sounds and passes away. Of this brook He drinks, He has not disdained to drink of this brook; for to drink of this brook was to Him to be born and to die. What this brook has, is birth and death; Christ assumed this, He was born, He died. "Therefore has He lifted up His head;" that is, because He was humble, and "became obedient unto death, even the death of the Cross: therefore God also has highly exalted Him, and given Him a Name which is above every name; that at the Name of Jesus every knee shall bow, of things in Heaven, and things in earth, and things under the earth; and that every tongue shall confess that Jesus Christ the Lord is in the glory of God the Father." [Philippians 2:8-11]

So, dearly beloved, “he rejoiced as a strong man to run the course.” Which course, if not the course of our mortality, which he was willing to share with us? This course is the way along which the human race passes. They all pass along it, you see, starting on it when they are born, finishing it when they die. And this stream of the human race from beginning to end is constantly issuing from the hidden sources of nature. It was from this rapid and turbulent stream that Christ was willing to drink. You heard just now in the psalm, “From the torrent he drank in the way.” This torrent has brought us to birth, has carried us on to death. As though from the hidden source of a spring, Christ has taken to himself the very depths of the sea. Each for our sake—he was both born and died.
