Galatians 2:7 "On the contrary, they recognized that I had been entrusted with the task of preaching the gospel to the uncircumcised,[a] just as Peter had been to the circumcised.[b] 8 For God, who was at work in Peter as an apostle to the circumcised, was also at work in me as an apostle to the Gentiles. 9 James, Cephas[c] and John, those esteemed as pillars, gave me and Barnabas the right hand of fellowship when they recognized the grace given to me."
OK - my bad. I see it in 2:8. I was checking Galatians 2:7. Regardless there is no splitting of Peter’s authority - the early church would attest to that.
