Not sure why you would say that.
Paul was converted and started preaching the Gospel to the Gentiles in Acts 9:3-43
And Peter was preaching to the Roman Centurion Cornelious in Acts 10:34-43 This was because an Angel told him to send for Peter.
Around 3 years later Peter Joined Paul's ministry to the Gentiles.
paul was converted in acts chapter nine , peter did first preach to the gentiles in acts ten .
And .
They both preach the gospel , the same one . what do it matter if it were paul or peter .
Specially when it seems so many are now running to that which is of anti christ and its ecumiencal interfaith .
Does it really matter in the end what one knew or didnt know if they end up serving anti christ . nope , not really .
I say that cause i see lots of debates , i also see lots of these debaters going under the same ecumeincal flow of anti christ .
But i do suppose paul could have also been preaching to the gentiles at first as well .
Do be encouraged grailhunter . And do beware of ecumeincalism .
