'St. Jerome, Venerable Bede, and St. Thomas say that though the graves were opened at the death of Christ, yet the dead did not rise till after the resurrection of the Lord. And this is conformable to what the Apostle says when he calls Christ the first begotten of the dead, and the first of them that rise. For it was not fitting that any man should rise before Him who had triumphed over death.'

St. Alphonsus Maria de Liguori
