But the scripture has consigned all under sin, that the promise by faith in Jesus Christ might be given to them that believe.
All Commentaries on Galatians 3:22 Go To Galatians 3
Augustine of Hippo
AD 430
Transgression of the law was needed to break the pride of those who, glorying in their father Abraham, boasted of having a sort of natural righteousness. They caused more harm to the Gentiles the more arrogantly they flaunted the merits of their circumcision. But the Gentiles could be humiliated very easily even without transgression of this sort of law, for the grace of the gospel found that these men, who knew that they had received no root of wisdom from their parents, were actually slaves to idols…. The law was therefore given not to take away sin but to include all under sin. For the law showed that to be sin which the Jews in their blindness deemed to be righteousness, so that by this humiliation they might know that their salvation was not in their own hands but in the hand of a mediator…. This very humility was fitted to the recognition of Christ, who is the paradigm of humility.
