As many as desire to make a fair show in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.
All Commentaries on Galatians 6:12 Go To Galatians 6
Augustine of Hippo
AD 430
The Jews were inflicting great persecution on those who seemed to be deserting their traditional observances such as circumcision. Paul’s lack of fear has been demonstrated through his composing such a letter in his own handwriting. In this way he shows that those who force the Gentiles into circumcision are operating under fear’s control, as though they were subject to the law.
