Mark 16:4

Neither the stone nor the bolts of the tomb
could hold Christ a captive;
Death lies conquered by him, he has
trampled on hell's fiery chasm.
With him a throng of saints ascended to
heavenly regions,
And to many he showed himself, letting
them see and touch him.

(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.

And they said to each other, "Who will roll away the stone for us from the door of the tomb?" And looking up, they saw that the stone had been rolled away. For it was very large. How the stone was rolled away by the angel, Matthew explains sufficiently. But the rolling away of the stone mystically suggests the uncovering of the mysteries of Christ, which were covered by the veil of the legal letter. For the law is written on stone, whose covering having been removed, the glory of the resurrection is shown, and the abolition of the ancient death and the eternal life to be hoped for by us began to be proclaimed throughout the whole world.

(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.

But while they were pondering this, the Angel rolled away the stone, though the women did not perceive it. So too Matthew says that the Angel rolled away the stone after the women had arrived. But Mark was silent about this, because Matthew had already said by whom the stone was rolled away.
