Holy Saturday

As Christ's death wrought our salvation, so likewise did His burial. Hence Jerome says (Super Marc. xiv): "By Christ's burial we rise again"; and on Isaiah 53:9: "He shall give the ungodly for His burial," a gloss says: "He shall give to God and the Father the Gentiles who were without godliness, because He purchased them by His death and burial."

Thomas Aquinas, ST III.51.1ad2
