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.

(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.

(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.

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.

(Hom. in Evan. 21) 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.

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.

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.

(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.

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.

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.

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)
