Peter Chrysologus, on Matt 28:1

“And in the end of the sabbath, when it began to dawn towards the first day of the week, came Mary Magdalen and the other Mary, to see the sepulchre.”

“(Serm. 74.) He said not ‘rolled,’ but rolled back; because the rolling to of the stone was a proof of death; the rolling it back asserted the resurrection. The order of things is changed; The Tomb devours death, and not the dead; the house of death becomes the mansion of life; a new law is imposed upon it, it receives a dead, and renders up a living, man. It follows, And sat thereon. He sat down, who was incapable of weariness; but sat as a teacher of the faith, a master of the Resurrection; upon the stone, that the firmness of his seat might assure the sted fastness of the believers; the Angel rested the foundations of the Faith upon that rock, on which Christ was to found His Church. Or, by the stone of the sepulchre may be denoted death, under which we all lay; and by the Angel sitting thereon, is shewn that Christ hath by His might subdued death.”
