ISB ~ 2 Corinthians 5 v21

made him to be sin:Jesus was not made a sinner or personally counted guilty of sin on the Cross. Rather, he bore the curse of death that mankind incurred because of sin (Gal 3:13; 1 Pet 2:22-24), even though he himself knew no sin, i.e., committed no sin (Jn 8:46; 1 Jn 3:5) (CCC 602-3).

• Paul adopts the idiom of the Greek OT, where “sin” is a shorthand expression for a Levitical “sin

offering” (Lev 4:21; 5:12; 6:25). Isaiah uses this same language for the suffering Messiah, who was expected to make himself an “offering for sin” (Is 53:10). the righteousness of God: An important expression in Paul’s writings. It can refer (1) to God’s own righteousness that is manifest to the world when he is faithful to his covenants (Rom 3:25-26) and (2) to the gift of righteousness that God imparts to the baptized (Phil 3:9). See note on Rom 1:17.
