How do you know this or can back it up?
In gal 2 it's recorded that peter was
living as a
gentile in antioch, it was ongoing he was LIVING, he then feared the circumcision, and withdrew, and started living as a jew again, then barnabas and the rest of the jews
did the same thing.
for them to follow in the same pattern and footsteps as peter, they had to be living as gentiles also, before thier turncoating back to judaism. They, the rest of the jews, and Barnabas did what peter did. They were all living as gentile prior to the circumcision visitors, who intimidated peter.
12 For before certain men came from James,
he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. 13 And the
rest of the Jews acted hypocritically
along with him, so that even
Barnabas was led astray by their hypocrisy. 14 But when I saw that their conduct was not in step with the truth of the gospel, I said to
Cephas before them all,
If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?
besides, Paul said he became as a gentile right in gal 4:12. How could paul and barnabas possibly live as jews, around the gentile converts?
