And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it.
All Commentaries on Matthew 28:2 Go To Matthew 28
Augustine of Hippo
AD 430
According to Matthew, the angel sat upon the stone which had been rolled from the tomb, whereas Mark says that upon entering the tomb the women were astounded to see a young man sitting on the right, dressed in a white robe. This discrepancy would be troubling unless we understand that Matthew remained silent concerning that angel whom they saw when they entered the tomb and Mark remained silent concerning that angel whom they saw sitting on the stone outside the tomb. If this be the case, the women saw two angels and heard from them about Jesus progressively; first from the one who sat on the stone outside the tomb and then from the one whom they saw sitting on the right when they entered the tomb. They went into the tomb then because they had been exhorted to do so by the angel sitting outside, when he said, “Come and see where the Lord was placed.” Upon entering, as it is written, they saw and heard similar things from the angel sitting on the right side of the tomb, who is mentioned by Mark but ignored by Matthew. If this explanation fails to satisfy, we certainly ought to understand that when they entered the tomb they were in some sort of walled enclosure which, it is reasonable to believe, had been established as a secured location in front of the rock from which the tomb was cut. According to this scenario, the angel whom they saw sitting on the right side of the tomb would have been in the same space as the angel who Matthew says was sitting on the stone which, at the time of the earthquake, had been rolled back from the entrance to the tomb, that is, from the sepulcher cut from the rock.
