Galatians 2:7-8

2:7 On the contrary, when they saw that I was entrusted with the gospel to the uncircumcised just as Peter was to the circumcised 2:8 (for he who empowered Peter for his apostleship to the circumcised also empowered me for my apostleship to the Gentiles)

Galatians 5:6

5:6 For in Christ Jesus neither circumcision nor uncircumcision carries any weight – the only thing that matters is faith working through love.

Galatians 5:11

5:11 Now, brothers and sisters, if I am still preaching circumcision, why am I still being persecuted? In that case the offense of the cross has been removed.
