He is beside Jesus at the time of the transfiguration. Amongst Roman Catholics, he is viewed as the first pope. And he is really the head of the church of the Christian followers, and they're not even called Christians at this point, in Jerusalem right over here. But we're going to talk about another significant apostle as well in this video, and that is Paul. And as we'll see, Paul is not mentioned in the first four books of the Bible. He wasn't a contemporary of Jesus, or at least he didn't know Jesus during his life. He did live at the same time, and you can see it on this timeline, where Jesus is born slightly before the common era.
