BOxley has decided that in his opinion, Paul messed things up. It doesn't seem like anything posted here will change that opinion.
I support his right to his opinion even if I do not agree with that opinion. Sure Paul did what he thought was best and he wasn't Jesus, but Jesus had the faith in Paul to do the right thing, and that to me is what counts. It doesn't matter to me if Paul was Jewish or not, Paul was apparently the one that Jesus had chosen to be the witness and spread the word. It seems to me, in my humble opinion, that Paul/Saul was born Jewish, was raised up in Rome and exposed to Roman (gentile) teachings, then saw Jesus and had his life turned around and became as a Jew again, but knew that he had to teach to Jews and Gentiles, the teachings of Jesus. After all, Jesus did heal more than just Jewish people on his travels.
Just my two cents.
