5 And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.
[AD 430] Augustine of Hippo on Mark 16:5
Mark tells us that the women entered the sepulcher, and there saw a young man sitting on the right side, covered with a long white garment, and that they were frightened. In Matthew's version, the stone was already rolled away from the sepulcher and the angel was sitting upon it. The explanation may be that Matthew has simply said nothing about the angel whom they saw when they entered into the sepulcher, and that Mark has said nothing about the one whom they saw sitting outside upon the stone. In this way they would have seen two angels, and have assumed two separate angelic reports.

[AD 430] Augustine of Hippo on Mark 16:5
(Con. Evang. iii. 24) Either let us suppose that Matthew was silent about that Angel, whom they saw on entering, whilst Mark said nothing of him, whom they saw outside sitting on the stone, so that they saw two and heard severally from two, the things which the Angels said concerning Jesus; or we must understand by entering into the sepulchre, their coming within some inclosure, by which it is probable that the place was surrounded a little space before the stone, by the cutting out of which the burial place had been made, so that they saw sitting on the right hand in that space him whom Matthew designates as sitting on the stone.

[AD 450] Peter Chrysologus on Mark 16:1-8
(occ. ap. Chrysologum, serm. 82) The women in this place run abroad with womanly devotion, for they do not bring Him faith as though He were alive, but ointments as to one dead; and they prepare the service of their grief for Him as buried, not the joys of heavenly triumph for Him as risen.

(Chrysologus ubi sup.) Your breast was darkened, your eyes shut, and therefore ye did not before see the glory of the opened sepulchre. It goes on: And they looked, and saw that the stone was rolled away.

(Chrysologus ubi sup.) Great indeed by its office rather than its size, for it can shut in and throw open the body of the Lord.

(Chrysologus ubi sup.) The women, then, entered the sepulchre, that being buried with Christ, they might rise again from the tomb with Christ. They see the young man, that is, they see the time of the Resurrection, for the Resurrection has no old age, and the period, in which man knows neither birth nor death, admits of no decay, and requires no increase. Wherefore what they saw was a young man, not an old man, nor an infant, but the age of joy.

(Chrysologus ubi sup.) Again, they saw a young man sitting on the right, because the Resurrection has nothing sinister in it. They also see him dressed in a long white robe; that robe is not from mortal fleece, but of living virtue, blazing with heavenly light, not of an earthly dye, as saith the Prophet, Thou deckest thyself with light as with a garment; and of the just it is said, Then shall the righteous shine forth as the sun. (Ps. 104:2) (Matt. 13:43)

(Chrysologus ubi sup.) The Angel indeed sits on the sepulchre, the women fly from it; he, on account of his heavenly substance, is confident, they are troubled because of their earthly frame. He who cannot die, cannot fear the tomb, but the women both fear from what was then done, and still, as being mortals, fear the sepulchre as mortals are wont.

(Chrysologus ubi sup.) It is said also in a marked manner, that they said nothing to any one, because it is the part of women to hear, and not to speak, to learn, not to teach.

[AD 604] Gregory the Dialogist on Mark 16:5
But we must note what it means that the angel is seen sitting on the right side. For what is designated by the left except the present life, and what by the right except eternal life? Hence it is written in the Song of Songs: "His left hand is under my head, and his right hand shall embrace me." Since therefore our Redeemer had already passed beyond the corruption of the present life, rightly the angel who had come to announce his eternal life was sitting on the right. He appeared covered with a white robe because he announced the joys of our festival. For the brightness of the garment proclaims the splendor of our solemnity. Should we say ours, or his? But to speak more truly, let us say both his and ours. For that resurrection of our Redeemer was both our festival, because it brought us back to immortality, and the festival of the angels, because by calling us back to heavenly things it filled up their number. Therefore at his own and our festival the angel appeared in white garments, because while we are brought back to heavenly things through the Lord's resurrection, the losses of the heavenly homeland are repaired.

[AD 604] Gregory the Dialogist on Mark 16:1-8
(Hom. in Evan. 21) But if we believe on Him who is dead, and are filled with the sweet smell of virtue, and seek the Lord with the fame of good works, we come to His sepulchre with spices. There follows: And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.

(ubi sup.) But the women who came with spices see the Angels; because those minds who come to the Lord with their virtues, through holy desires, see the heavenly citizens. Wherefore it goes on: And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.

(ubi sup.) But what is meant by the left hand, but this present life, and what by the right, but everlasting life? Because then our Redeemer had already gone through the decay of this present life, fitly did the Angel, who had come to announce His everlasting life, sit on the right hand.

(ubi sup.) Or else, he appeared covered with a white robe, because he announced the joys of our festivity, for the whiteness of the robe shows the splendour of our solemnity.

(ubi sup.) As though he had said, Let them fear, who love not the coming of the inhabitants of heaven; let them fear, who, weighed down with carnal desires, despair that they can ever attain to their company; but why should ye fear, ye who see your own fellow citizens.

(ubi sup.) But let us hear what the Angel adds; Ye seek Jesus of Nazareth. Jesus means the Saviour, but at that time there may have been many a Jesus, not indeed really, but in name, therefore the place Nazareth is added, that it might be evident of what Jesus it was spoken. And immediately he subjoins the reason, Which was crucified.

(ubi sup.) He is not here, is spoken of His carnal presence, for He was not absent from any place as to the presence of His majesty.

(ubi sup.) If again the Angel had not expressly named him who had denied his Master, he would not have dared to come amongst the disciples; he is therefore called by name, lest he should despair on account of his denial.

(ubi sup.) For Galilee means 'a passing over;' for our Redeemer had already passed from His Passion to His resurrection, from death unto life, and we shall have joy in seeing the glory of His resurrection, if only we pass over from vice to the heights of virtue. He then who is announced at the tomb, is shown in 'passing over,' because He who is first known in mortification of the flesh, is seen in this passing over of the soul.

[AD 636] Isidore of Seville on Mark 16:5
Why a “young man”? The resurrection of the dead, as the apostle declares, will be “unto the fullness of the measure of the stature of Christ,” that is, in the season of youth, which needs no further development and which is free from all defect, complete in every respect, having fullness of strength.
[AD 735] Bede on Mark 16:5
And entering into the tomb, they saw a young man sitting on the right side, clothed in a white robe, and they were amazed. Entering from the east into that round house carved in the rock, they saw an angel sitting on the southern part of that place, where the body of Jesus had been laid, for this was indeed on the right side. For surely the body, lying supine with its head towards the west, must have its right side towards the south. Matthew writes that they first saw the angel who rolled back the stone from the door of the tomb sitting upon the stone, who commanded them to enter the place where the Lord had been laid and to see that He had already risen from the dead. Luke writes that entering the tomb, they found two angels standing there. Therefore, the women who came with spices saw the angels, for indeed those minds see the heavenly citizens who, with virtues, travel to God through holy desires. We must note, indeed, what it means that the angel is seen sitting on the right hand. For what is signified by the left but the present life? And by the right but eternal life? Hence it is written: "His left hand is under my head, and his right hand shall embrace me." (Cant. II). For the Church places the left hand of God, namely the prosperity of the present life, as under the head, which it presses with the intention of supreme love. But God's right hand embraces it, because under its eternal bliss it is wholly contained with devotion. Therefore, because our Redeemer had already passed beyond the corruption of the present life, rightly did the angel who came to announce His eternal life sit at the right. He appeared clothed in a white robe because he announced the joys of our festivity. For the whiteness of the garment signifies the splendor of our festivity. Let us say ours or his? But to more truly confess, let us say both his and ours. For the resurrection of our Redeemer was both our festivity because it restored us to immortality, and the festivity of angels, because by bringing us back to the heavens, it fulfilled their number. Therefore, in his and our festivity, the angel appeared in white garments, because as we are led back to heaven through the resurrection of the Lord, the losses of the heavenly homeland are repaired. But now, let us hear him who addresses the women who come.

[AD 735] Bede on Mark 16:1-8
(in Marc. 4, 45) As then the women show the great fervency of their love, by coming very early in the morning to the sepulchre, as the history relates, according to the mystical sense an example is given to us, that with a shining face, and shaking off the darkness of wickedness, we may be careful to offer the fragrance of good works and the sweetness of prayer to the Lord.

(ubi sup.) Or else, by this phrase is meant the first day from the day of sabbaths, or rests, which were kept on the sabbath. There follows: And they said among themselves, Who shall roll us away the stone from the door of the sepulchre?

(ubi sup.) Matthew shows clearly enough, that the stone was rolled away by an Angel. This rolling away of the stone means mystically the opening of the Christian sacraments, which were held under the veil of the letter of the law; for the law was written on stone. It goes on: For it was very great.

(ubi sup.) Now they saw a young man sitting on the right side, that is, on the south part of the place where the body was laid. For the body, which was lying on its back, and had its head to the west, must have had its right to the south.

[AD 1107] Theophylact of Ohrid on Mark 16:5
If Matthew says that the Angel was sitting on the stone, while Mark says that the women, having entered the tomb, saw him sitting inside, one should not be troubled by this. For they could have seen the Angel sitting outside on the stone, as stated in Matthew, and could have seen him again inside the tomb, as having preceded them and gone in. However, some say that the women mentioned in Matthew were different from those in Mark, and that the Magdalene was the companion of all, as the most zealous and fervent.

[AD 1107] Theophylact of Ohrid on Mark 16:1-8
For they do not understand the greatness and dignity of the wisdom of Christ. But they came according to the custom of the Jews to anoint the body of Christ, that it might remain sweet-smelling, and might not burst forth into moisture, for spices have the property of drying up, and absorb the moisture of the body, so that they keep the body from corruption.

He says, On the first of the sabbaths, (μιᾱς σαββάτων.) that is, on the first of the days of the week. For the days of the week are called sabbaths, and by the word 'una' is meant 'prima.'

Though Matthew says that the Angel was sitting on the stone, whilst Mark relates that the women entering into the sepulchre saw a young man sitting, yet we need not wonder, for they afterwards saw sitting within the sepulchre the same Angel as sat without on the stone.

But some say the women mentioned by Matthew were different from those in Mark. But Mary Magdalene was with all parties, from her burning zeal and ardent love.

For he does not blush at the Cross, for in it is the salvation of men, and the beginning of the Blessed.

As if he had said, Do ye wish to be certain of His resurrection, he adds, Behold the place where they laid him. This too was the reason why he had rolled away the stone, that he might show the the place.

That is, they trembled because of the vision of Angels, and were amazed because of the resurrection.

Either on account of the Jews, or else they said nothing because the fear of the vision prevented them.

[AD 1274] Pseudo-Jerome on Mark 16:1-8
After the sadness of the sabbath, a happy day dawns upon them, which holds the chief place amongst days, for in it the chief light shines forth, and the Lord rises in triumph. Wherefore it is said, And when the sabbath was past, Mary Magdalene, and Mary the mother of James and Salome, had bought sweet spices.

By very early in the morning, (Luke 24:1. diluculo Vulg.) he means what another Evangelist expresses by at the dawning. But the dawn is the time between the darkness of night, and the brightness of day, in which the salvation of man is coming forth with a happy closeness, to be declared in the Church, just as the sun, when he is rising and the light is near, sends before him the rosy dawn, that with prepared eyes she may bear to see the graciousness of his glorious brightness, when the time of our Lord's resurrection has dawned; that then the whole Church, after the example of the women, may sing the praises of Christ, since He has quickened the race of man after the pattern of His resurrection, since He has given life, and has poured upon them the light of belief.

The white robe is also true joy, now that the enemy is driven away, the kingdom won, the King of Peace sought for and found and never let go by us. This young man then shows an image of the Resurrection to them who feared death. But their being frightened shows that eye hath not seen, nor ear heard, neither have entered into the heart of man to conceive the things which God hath prepared for them that love Him. (1 Cor 2:9) There follows, And he saith unto them, Be not affrighted.

For there is no fear in love. Why should they fear, who had found Him whom they sought?

But the bitter root of the Cross has disappeared. The flower of life has burst forth with its fruits, that is, He who lay in death has risen in glory. Wherefore he adds, He is risen; he is not here.

But immortality is shown to mortals as1 due to thankfulness, that we may understand what we were, and that we may know what we are to be. There follows, But go your way, tell his disciples and Peter that he goeth before you into Galilee. The women are ordered to tell the Apostles, that as by a woman death was announced, so also might life rising again. But He says specially unto Peter, because he had shown himself unworthy of being a disciple, since he had thrice denied his Master; but past sins cease to hurt us when they cease to be pleasing to us.

This sentence is but short in the number of syllables, but the promise is vast in its greatness. Here is the fountain of our joy, and the source of everlasting life is prepared. Here all that are scattered are brought together, and the contrite hearts are healed. There, he says, ye shall see Him, but not as ye have seen Him.

This also is spoken of the life to come, in which grief and groaning will flee away. For the women prefigure before the resurrection all that is to happen to them after the resurrection, namely, they flee away from death and fear. There follows, Neither said they any thing to any man, for they were afraid.

[AD 1274] Glossa Ordinaria on Mark 16:1-8
(ord. ex Bedâ.) For these religious women after the burial of the Lord, as long as it was lawful to work, that is, up to sunset, prepared ointment, as Luke says. (Luke 23:56) And because they could not finish their work from the shortness of the time, when the sabbath was over, that is, at sunset, as soon as the time for working came round again, they hastened to buy spices, as Mark says, that they might go in the morning to anoint the body of Jesus. Neither could they come to the sepulchre on the evening of the sabbath, for night prevented them. Wherefore it goes on: And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
