Christ has redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangs on a tree:
All Commentaries on Galatians 3:13 Go To Galatians 3
John Chrysostom
AD 407
For the people were liable to punishment since they had not fulfilled the whole law. Christ satisfied a different curse: the one that says “Cursed is everyone that hangs on a tree.” Both the one who is hanged and the one who transgresses the law are accursed. Christ, who was going to lift that curse, could not properly be made liable to it yet had to receive a curse. He received the curse instead of being liable to it and through this lifted the curse. Just as, when someone is condemned to death, another innocent person who chooses to die for him releases him from that punishment, so Christ also did…. Just as by dying he snatched from death those who were going to die, so also when he suffered the curse he released them from the curse.
