The Tübingen school of historians founded by F. C. Baur believes that in Early Christianity, there was conflict between Pauline Christianity and the Jerusalem Church led by James the Just, Simon Peter, and John the Apostle, the so-called "Jewish Christians" or "Pillars of the Church".[113] Paul believed that the gentiles and Jewish Christians were no longer obligated to keep the Mosaic law (Gal 2:21). The Jewish Christians disagreed, believing that everyone, including the gentiles, must keep the Mosaic law. In Galatians 2:14, part of the "Incident at Antioch",[114] Paul publicly rebuked Peter for judaizing.
