And the important thing to realize about Paul, it's a controversy, to what degree should the teachings of Jesus be spread to the Gentiles, to the non-Jewish people? There are these famous debates. And Paul's view is, no, we should not force the Gentiles to do everything that the Jews have to do, the circumcision, the Jewish dietary laws. And you can imagine, this doubly angers the church leaders. Not only is he spreading the word of Jesus that has annoyed them to no end, but he also wants to spread it to the Gentiles, but he doesn't think that the Gentiles need to perform all of the things that the Jewish leaders believe are dictated by the laws of Moses, by the Jewish faith. And circumcision is actually a major debate, circumcision, the dietary habits, et cetera, et cetera. So eventually, he goes back to Jerusalem to face this leadership.
