So in the mid-40s here, let me, in the mid-40s, right over here, he does a missionary journey, once again, Antioch is his base, he goes to Cyprus and southern mid, what we would call Turkey today, and in the early 50s, he goes on this fairly long journey through modern-day Turkey, through Macedonia, through Greece, and as he's doing this, he's spreading the word of Jesus Christ, he's starting to help establish churches in these significant places, Philippi, Thessalonica, Corinth, all of these various places. You see his third journey here, very similar in path in yellow to the second journey, he does that in the late 50s CE. And once again, he's constantly establishing these churches. 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.
