Hebrews 4:12

The texts of the New Testament, which we have discussed, are things said by Himself about Himself. Isaiah, however, He said that His mouth had been set by His Father as a sharp sword, and that He was hidden under the shadow of His hand, made like to a chosen shaft and kept close in the Father's quiver, called His servant by the God of all things, and Israel, and Light of the Gentiles. The mouth of the Son of God is a sharp sword, for "The word of God is living, and active, and sharper than any two-edged sword, and piercing to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart." And indeed He came not to bring peace on the earth, that is, to corporeal and sensible things, but a sword, and to cut through, if I may say so, the disastrous friendship of soul and body, so that the soul, committing herself to the spirit which was against the flesh, may enter into friendship with God. Hence, according to the prophetic word, He made His mouth as a sword, as a sharp sword. Can any one behold so many wounded by the divine love, like her in the Song of Songs, who complained that she was wounded: "I am wounded with love," and find the dart that wounded so many souls for the love of God, in any but Him who said, "He hath made Me as a chosen shaft."

Jesus endured the cross, disregarding the shame, and therefore is seated at the right hand of God. And those who imitate him by disregarding the shame shall sit with him and rule in the heavens with him, who came not to bring peace upon the earth but upon the souls of his followers and to bring a sword upon the earth. Since "the Word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart," this word above all now bestows on our souls the prize of that peace which surpasses all understanding, which he left to his apostles. And it brings a sword between the earthly image and the heavenly in order that when he receives our heavenly image we may be made fully heavenly, if we are worthy not to be cut in two.

And Scripture calls by the name of "sword" the Word which has the power of trying and of discerning thoughts and which "extends even to the division of soul and spirit, of joints and marrow." … Every soul at the time of the passion was subjected to a sort of test, as it were, according to the words of the Lord, who said, "You will all fall away because of me." Simeon prophesies concerning Mary that, standing beside the cross and looking at what was happening and hearing his words—even after the testimony of Gabriel, after the secret knowledge of her divine conception, after the great showing of miracles—"Even you will flee," he says, "a certain perplexity about your soul." For the Lord must taste of death for the sake of all, and, being made a propitiation for the world, he must justify all people in his blood. Therefore, some doubt will touch even you yourself who have been taught from above concerning the Lord. That is the sword. "That the thoughts of many hearts may be revealed," meaning that, after the scandal which happened at the cross of Christ to both the disciples and to Mary herself, some swift healing will follow from the Lord, confirming their hearts in their faith in him. Thus we see that even Peter, after having stumbled, clung more firmly to his faith in Christ. What was human, therefore, was proved unsound in order that the power of the Lord might be manifested.

For God says, 'I will dwell among them and walk among them, and I will be their God.' So when the fear of divine power returns to the perception of the soul, then we blush, then we desire to hide, then being placed in the thoughts of our sins, we are found in the midst of the tree of paradise where we sinned, desiring to hide, and thinking that God does not seek the hidden things. But the searcher of hearts and thoughts, penetrating even to the division of the soul, says, 'Adam, where are you?' ... But when He said, 'Where are you?' He is not seeking the place which knew His secret, for God does not have closed eyes so as not to see what is hidden. But God sees the faults of all and knows the offenses of all: he has eyes over every soul, over all hidden things. So, where are you, Adam? That is, not in what place, but in what state are you. Therefore, it is not an inquiry, but a rebuke.

In the next place, lest hearing the words "after the same example," thou shouldest think that the punishment is the same, hear what he adds; "For the Word of God is quick and powerful, and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." In these words he shows that He, the Word of God, wrought the former things also, and lives, and has not been quenched.

Do not then when hearing the Word, think of it lightly. For "He is sharper," he says, "than a sword." Observe His condescension; and hence consider why the prophets also needed to speak of saber and bow and sword. "If ye turn not," it is said, "He will whet His sword, He hath bent His bow and made it ready." (Ps. vii. 12.) For if now, after so long a time, and after their being perfected, He cannot smite down by the name of the Word alone, but needs these expressions in order to show the superiority arising from the comparison of the Gospel with the law: much more then of old.

"Piercing," he says, "even to the dividing asunder of soul and spirit." What is this? He hinted at something more fearful. Either that He divides the spirit from the soul, or that He pierces even through them disembodied, not as a sword through bodies only. Here he shows, that the soul also is punished, and that it thoroughly searches out the most inward things, piercing wholly through the whole man.

"And is a discerner of the thoughts and intents of the heart, neither is there any creature that is not manifest in His sight." In these words most of all he terrified them. For do not (he says) be confident if ye still stand fast in the Faith, but without full assurance. He judges the inner heart, for there He passes through, both punishing and searching out.

For lest on hearing the things that belong to the soul we should grow negligent, he adds also what concerns the body. For then it is as a king, when his officers are guilty of some great fault, first strips them (say) of their command, and after depriving them of their belt, and their rank, and their herald, then punishes them: so also in this case the sword of the Spirit works.

Then, lest any think that they will simply be deprived of rest only, he adds also the punishment, saying, "For the Word of God is quick, and powerful; and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow: and is a discerner of the thoughts and intents of the heart." Here he is speaking of Hell and of punishment. "It pierceth" (he says) into the secrets of our heart, and cutteth asunder the soul. Here it is not the failing of carcasses nor, as there, the being deprived of a country, but of a heavenly kingdom; and being delivered to an everlasting hell, and to undying punishment and vengeance.

He says, "division of soul and spirit." The soul has a special feeling for the body, but the grace of the Holy Spirit draws against the body to the heavenly things.

He did not come "to bring peace on earth … but a sword," and Scripture calls the Word of God a "two-edged sword" because of the two Testaments.

He used the phrase "laid bare to the eyes of him" as a metaphor from sacrificed beasts, which lie completely mute, the slaughter doing away with their life, and along with their life their cries. In similar manner, he is saying, when we also are judged, we behold everything done by us in ungodly or lawless fashion, whereas we receive the sentence of punishment in silence, realizing as we do its justice.

John who had been exiled by the Emperor Marcion, said, 'One day we went into Syria to see Poemen for we wanted to ask him about hardness of heart. But he did not know Greek and we did not have an interpreter. When he saw we were embarrassed, he began to speak in Greek saying, 'The nature of water is soft, the nature of stone is hard; but if a bottle is hung above a stone letting water drip down, it wears away the stone. It is like that with the word of God; it is soft and our heart is hard, but if a man hears the word of God often, it will break open his heart to the fear of God.'

"For the word of God is living." It gradually shows that Christ alone was the one who acted in what happened concerning the children of Israel. For it is living, he says, and will live forever. But lest they think that those who sin and provoke Christ are only frustrated by the earth as the ancients were, he adds a more terrible deed.
"sharper than any two-edged sword." As those who did not hear the speech might fear something more terrible, it expresses what has been said, adapting examples that are among us: for it could not be understood in any other way than what is said, cutting from both sides with any sword.
"piercing to the division of soul and spirit." He says something fearful: either that the spirit separates from the soul, and leaves it desolate of the holiness that the Lord in the gospel called division; (for just as a king, when a ruler sins, is stripped of his belt and his office beforehand, and then punished; so here too the spiritual dignity is first taken away from the person, then he is punished;) or that it even reaches the incorporeal themselves.
The holy Cyril certainly received in a certain place: piercing to the division of soul and spirit: He says that the preaching concerning God divides and distinguishes the parts of the soul, making them receptive and capable of the things heard. That it also reaches them, he says, of the incorporeal beings, and punishes the soul. That it works a division of soul and spirit. It is indeed fearful.
In another way.

The division that the Gospels threaten, the Fathers understood as the complete abandonment of the Holy Spirit. Therefore, I think it is now a day that causes the separation of the Holy Spirit, and it removes itself from the soul, after which all good things will subsequently follow and be taken away.

"of joints and marrow." So that, having heard the things of the soul, they do not become careless, as if the punishment were unclear, having spoken of the incorporeal, he also speaks of the corporeal; for the more visible things strike with greater fear.
"and discerning the thoughts." To distinguish and examine the very thoughts themselves, and the invisible concepts of the heart. Here the divinity of the Word is shown; for it is God who examines, that is, who tests and knows the thoughts; he says "God searches the hearts and kidneys." (Jer. 17:10).

"The word of God is … sharper than any two-edged sword." Now the holy depth of divine Scripture is expressed in such common language that everyone immediately takes it in. But buried within it are hidden senses of truth, so that the vital meaning must be most carefully sought out. What contributes most of all to our understanding that it is really divine is the fact that ignorant persons are known to have been able to explain most subtle things, and mortal humans eternal things, but only when filled with the divine Spirit.

Do you not shudder when you hear God each day saying to you through the whole of the divine Scripture, "Let no evil speech come out of your mouth"? For truly I say to you for any idle word you will give an account, and for every cup of cold water you will receive a reward. Have you not heard that God is the judge of the "thoughts and intentions of the heart"? What does it say? "He who looks at a woman with desire has already committed adultery with her in his heart." Do you not see how he who looks with desire upon someone is considered an adulterer? Know then, surely, that those who strongly desire wealth are considered greedy, even if they have acquired nothing at all. Those who strive for many costly foods are gluttons, even if because of poverty they survive on only bread and water. They are sexually immoral who imagine many defiling encounters, even if they never look at another person. So too is it with those who say in their heart, "This has gone badly and become unreasonable" and "Why has this happened?" or "Why has that not happened?" Let them not be deceived, they are slanderers and will be judged as those who condemn, even though not a word comes out of their mouths nor does anyone hear them.

Just as then, he says, it was not war, not the sword that destroyed them, but the word of God—for they fell of their own accord—so it will be with us as well. For the same word that punished them will also punish us: it always lives and has not perished. And in yet another sense he said "living," so that you, upon hearing "word," would not consider it an empty utterance; he says "living," that is, substantial and effective, and upon whatever soul it falls, it inflicts blows. Notice his adaptation, how he recalled the sword and the blow, things customary and familiar to us—and this in order to show us from this the superiority of the power of the word of God.

He says something fearsome: either that the word of God separates the spirit from the soul and leaves it deprived of the holiness that comes from it, which the Lord also called "cutting asunder" in the Gospel (Matt. 24:51). For just as a king first strips a commander who has committed a crime of his belt and rank, and only then punishes him, so too in this case a person is deprived of spiritual dignity and then punished. Or that it penetrates even bodiless beings. Some have understood this passage, in my opinion, in a way inconsistent with the apostle's own intention: that the word of God, having entered the soul, divides and dissects it into parts, making it capable of receiving and containing the mystery. For just as an arrow, by cleaving the body, penetrates into it in this way, so too the word, if it did not divide the joined parts of the soul, could not enter into it.

Lest, hearing about the parts of the soul, they become careless in the assumption that this is an unknown punishment, he also puts forward about the bodily members. For what is more evident and open has a stronger effect.

Here he shows the divinity of the Word. For it is proper to God to judge, that is, to try and to know the thoughts. "For," he says, "You try the hearts and reins, O God" (Ps. 7:10).

It was necessary that our Hierarch be endowed with awareness, in regard to the threefold wisdom within Him: the innate, that is, the wisdom of angels and of the first man, the infused, and the eternal. Through the first, He knows all things which we are able to know by means of the proper disposition; through the second, He comprehends gloriously and infinitely, because "to His wisdom there is no limit"; through the third, He comprehends all things. For the One who was to restore the whole universe had to know the conditions of the whole universe. Hence, in the Epistle to the Hebrews: "The Word of God is living and efficient." And later: "All things are naked and open to the eyes of Him to whom we have to give account." Hence, it was necessary not only that He be powerful, but also that He be aware.

Then (v. 12) he gives the reason for this advice, and especially in regard to the danger. But this reason is taken on the part of Christ in Whom there are two natures: one is the divine according to which he is the Word of the Father; the other is the human according to which He is the high priest offering Himself on the Cross. First, therefore, he gives the reason based on the divinity; secondly, the reason based on the humanity (v. 14). He says three things about the Son of God: first, he describes His power; secondly, His knowledge (v. 12); thirdly, his authority (v. 13b). But he shows his power in three ways: first, its nature, secondly, its vigor (v. 12b); thirdly its action (v. 12c).

He says, therefore, The word of God is living. This text is difficult, although it is clearer than another text: for where we have sermo the Greek has logos, which is the same as verbum, 'word'; hence a saying, i.e., a word. This is the way Augustine explains John's statement: 'The word that I have spoken', i.e., I who am the Word: 'Your almighty word leapt down from heaven from the royal throne' (Wis. 18:15). Similarly here, the word (sermo) of God is living, i.e., the living Word (Verbum) of God. For the Word of God conceived from all eternity in the intellect of the Father is the primordial Word of which Sirach (1:5) says: 'The word of God on high is the fountain of wisdom.' And because it is primordial, all other words are derived from it; these words being nothing more than certain conceptions expressed in the angelic mind or ours, hence, that Word is the expression of all words, being their font. And what is said of that Word is somehow applied to the other words according to their mode. But it is said of that Word that it is living. But a thing is called living, when it has its own movement and activity. For as a gushing fountain is called living, so, too, that Word has eternal vigor: 'For ever, O Lord, your word stands firm in heaven' (Ps. 118:89); 'For as the Father has life in himself, so he has given to the Son also to have life in himself' (Jn. 5:26). Or it can be referred to His human nature, for it is living, although others may regard it as dead; because it rose no more to die: 'I was dead, and behold, I am living for ever and ever' (Rev. 1:18). Similarly, the word of Scripture is living and unfailing: 'Not as though the word of God had miscarried' (Rom. 9:6).

Then when he says, and active [effectual], he shows its vigor. But the word is said to be effectual because of its supreme power and the infinite force it has: for all such things were made by it: 'By the word of the Lord the heavens were established' (Ps. 32:6); it is also effectual, because all the words uttered by God and delivered by angels or man draw their efficacy from it: 'His word is full of power' (Ec. 8:4); 'The word which shall go forth shall not return to me void, but it shall do whatsoever I please, and it shall prosper in the things for which I sent it' (Is. 55:11).

Then (v. 12b) he shows its action. In regard to this he does two things: first, he describes its action; secondly, he explains this (v. 12c).

He says, therefore: And more piercing than any two-edged sword. But this is said to pierce which enters the depths of a thing. But this can take place in two ways: in one way, because it acts on the inmost recesses of a thing: 'You have wrought all our works for us' (Is. 26:12); in another way, because it knows the innermost parts of a thing: 'He needed not that any should give testimony of man: for he knew what was in man' (Jn. 2:25); 'I will penetrate to all the lower parts of the earth' (Sir. 24:43). For God's action and knowledge reach into the inmost parts of a thing; hence, he says, than any two-edged sword. For a sword is more penetrating, because it is sharp; and this is especially true of a two-edged sword, which is sharp at both ends. And because the word of God is sharp in its action and its knowledge, it is compared to a two-edged sword: 'And the sword of the spirit which is the word of God' (Eph. 6:17); 'In that day the Lord with his hard and great and strong sword shall visit Leviathan' (Is. 27:1). Or it is called two-edged in regard to its activity, because it is sharp enough to promote good and destroy evil: 'From his mouth came out a sharp two-edged sword' (Rev. 1:16). Or in regard to its knowledge, and it is said to be more piercing than any two-edged sword, i.e., than any human intellect, which is called two-edged, because it is open to either part of a conclusion, until it comes to the end of its scrutiny and fixes its point there, namely, in the truth. For in the ordering of causes we see that a prior cause works at a greater depth than a subsequent one. Hence, that which nature produces is more profound than that which is produced by art. Therefore, because God is the first cause, by His action is produced that which is most inward in a thing, namely, its being.

Then when he says, and piercing the division of the soul and of the spirit, he manifests what he had said above about its action. In regard to this he does two things: first, he shows this in regard to spiritual things; secondly, in regard to material things (v. 12d).

According to the Apostle there are three things in man: body, soul, and spirit: 'That you wholly spirit and soul and body may be preserved blameless in the coming of our Lord' (1 Th. 5:23). For we know what the body is. But the soul is that which gives life to the body; whereas the spirit in bodily things is something subtle and signifies immaterial substance: 'Egypt is man and not God: and their horses, flesh, and not spirit' (Is. 31:3). Therefore, the spirit in us is that by which we are akin to spiritual substances; but the soul is that through which we are akin to the brutes. Consequently, the spirit is the human mind, namely, the intellect and will. This has led some to assert that there are different souls in us: one which perfects and vivifies the body and is called a soul in the proper sense; another is the spirit, having an intellect by which we understand and a will by which we will. Consequently, those two are called substances rather than souls. But this opinion was condemned in the book, The Dogmas of the Church. Therefore, we must say that the essence of the soul is one and the same, and by its essence it vivifies the body, and by its power, which is called the intellect, it is the principle of understanding eternal things. How this is possible will be clear. For the more perfect a form is, the less its activity depends on matter. Thus the forms of the elements, because they are most imperfect, do not extend beyond matter. Therefore, since the soul is the most noble of forms, it should have an action which altogether transcends the power of matter. That action is called understanding, on which follows its natural inclination, namely, willing. But there is a triple difference among the actions of the soul: first of all, the soul is that to which pertain the powers by which the soul acts in conjunction with the body; whereas the spirit is that to which pertain the powers by which it acts without the body. But the first difference between those powers and the actions proceeding therefrom is the difference between reason and sensibility, which is a power through which the soul acts with the body; because reason apprehends universals, but the sensibility material and sensible things. The second difference is between the parts of the sensibility, because the sensibility has one state insofar as it tends to its proper object according to its nature, and another state insofar as it is regulated by reason. For the concupiscible appetite is considered one way when it is regarded as a force relative to its object, and another way when it is regarded as partaking of reason. The third difference is between the parts of reason itself relative to its different objects: because it either tends to God, and this is supreme in it; or to spiritual effects, or to temporal effects. The Word of God effects and distinguishes between all those divisions and species, namely, how the sensibility is distinguished from reason; also, the species of the same sensibility in itself; also, the species of the function of reason, and what arises in the rational soul from the consideration of spiritual and earthly things. Or it can be explained according to a Gloss in two ways: so that the soul refers to carnal sins which involve bodily pleasures, such as lust and gluttony; but the spirit refers to spiritual sins, which involve an act of the mind, such as pride, vain glory, and the like. Or by soul is understood evil thoughts, and by spirit good thoughts. Then the sense is this: reaching, i.e., discerning, unto the division of the soul and the spirit, i.e., between carnal and spiritual sins, or between good and evil thoughts.

Then when he says, of joints and of marrow, he declares what he had said about God's activity in regard to temporal things. But it should be noted that something fails to penetrate something else for two reasons: one is due to juncture and the other to concealment. But neither of these can impede the word of God. There are in us, of course, certain joints, namely, of nerves and arteries; and there are parts which are enclosed and hidden, such as the marrow enclosed in the bones. But all these are open to the divine gaze; consequently, there is nothing too difficult for Him to penetrate. Or by joints can be understood the union of the soul's parts to one another, as soul to spirit. As if to say: Not only does He reach to a knowledge of the difference and division of the soul and spirit, but to a knowledge of how they are joined. For he knows how the sensibility is ruled by reason. But marrow can be taken to mean that which is concealed in the reason and sensibility: 'Fear him that can send both body and soul to hell' (Mt. 10:28).

Then (v. 12d) he treats of the Word's knowledge. In regard to this he does two things: first, he shows that all things are subject to His knowledge; secondly, how He knows (v. 13b).

There are two reasons why a thing is not known: either because it is concealed within something; this is the way the secrets of the heart are concealed, because it is very deep and inscrutable: 'The heart is perverse above all things and inscrutable' (Jer. 17:9). In the heart thoughts are concealed, but the Word of God knows them: 'Take away the evil of your devices from my eyes' (Is. 1:16). Therefore, in regard to this he says, a discerner of thoughts. In another way, something is not known, because it is altogether unknown and invisible; which is the way the things of the will are unknown. But in the will is one's intention, which is invisible of its very nature. For what a man does or thinks is revealed in his work, but the intention for which he does it is utterly uncertain. But not even these are hidden from God; hence, he continues, and intentions of the heart: 'The searcher of hearts and reins', i.e., of thoughts and intentions (Ps. 7:11).

But it should be noted that the word, penetrating, can refer to an action, as has been said: then penetrator and discerner differ: but if it refers to thought, then the phrase, discerner of thoughts, explains it. As if to say: You say that it is more penetrating than any two-edged sword; this is true, because it is a discerner of the joints and the marrow, i.e., of thoughts and intentions. For joints are junctures, and, thus, thought in which there is a juncture of terms can be called a joint, when it passes from one thing to another: 'Loose the bands of wickedness' (Is. 58:6); 'Woe to you that draw iniquity with cords of vanity and sin as the rope of a cart' (Is. 5:18). Also, marrow is something that lies within and is concealed in the bones: 'His bones are moistened with marrow' (Jb. 21:24).
