To redeem them that were under the law, that we might receive the adoption as sons.
All Commentaries on Galatians 4:5 Go To Galatians 4
Gaius Marius Victorinus
AD 400
Since the law by its precepts held people bound, as it were, only to decency of life but not to the hope of deliverance and eternity, God sent his own Son. He sent him subject to the law, that is, the law of Israel, that he might redeem those who were there and lived under the law. Now this is a great thing, that he says [Christ came] not merely to show them the way of life or to stir them up toward eternity with harsh commands but to redeem them. This is the mystery of what he performed, the redemption of all who believed in him, that they might become sons by adoption. When, therefore, such a great benefit came from Christ, nothing was to be added beside this. The law was no longer a matter of servitude. .
