(For he that worked effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)
All Commentaries on Galatians 2:8 Go To Galatians 2
Jerome
AD 420
Paul allows that Peter, following Jewish custom, was without blame in his temporary observation of what was amiss so as not to lose those entrusted to him. But it was Paul’s own duty for the sake of the gospel truth to do what was entrusted to him among the uncircumcised, so that the Gentiles would not depart from their faith and belief in Christ through fear of the burdens and rigor of the law. –.
