"An angel descended and rolled back the stone. He did not roll back the stone to provide a way of escape for the Lord but to show the world that the Lord had already arisen. He rolled back the stone to help his fellow servants believe, not to help the Lord rise from the dead. He rolled back the stone for the sake of faith, because it had been rolled over the tomb for the sake of unbelief. He rolled back the stone so that he who took death captive might hold the title of Life. Pray, brothers, that the angel would descend now and roll away all the hardness of our hearts and open up our closed senses and declare to our minds that Christ has risen, for just as the heart in which Christ lives and reigns is heaven, so also the heart in which Christ remains dead and buried is a grave. May it be believed that just as he died, so was he transformed. Christ the man suffered, died and was buried, as God, he lives, reigns, is and will be forever."
Peter Chrysologus, Sermon 75.4
