Through the transgression of Adam all mankind was condemned:
“Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one Man’s righteous act the free gift came to all men, resulting in justification of life” (Rom. 5:18)
Christ took the curse of mankind upon Himself:
“Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, ‘Cursed is everyone who hangs on a tree’)” (Gal. 3:13)
Christ redeemed man with His Blood:
“knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, but with the precious blood of Christ, as of a lamb without blemish and without spot” (1 Pet. 1:18-19)
“And they sang a new song, saying: ‘You are worthy to take the scroll, and to open its seals; for You were slain, and have redeemed us to God by Your blood out of every tribe and tongue and people and nation’” (Rev. 5:9)
