And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up its place with flesh;
All Commentaries on Genesis 2:21 Go To Genesis 2
Jerome
AD 420
“God took a rib from the side of Adam and made it into a woman.” Here Scripture said aedificavit (“built”). The concept of building intends to denote the construction of a great house; consequently Adam’s rib fashioned into a woman signifies, by apostolic authority, Christ and the church, and that is why Scripture said he formed (aedificavit) a woman from the rib. We have heard about the first Adam; let us come now to the second Adam and see how the church is made (aedificatur) from his side. The side of the Lord Savior as he hung on the cross is pierced with a lance, and from it there comes forth blood and water. Would you like to know how the church is built up from water and blood? First, through the baptism of water, sins are forgiven; then, the blood of martyrs crowns the edifice.
