His teaching in the one scarcely presents a trace of the strong and clearly defined doctrines of the other, and the character and conduct of the Paul of Acts are altogether different from those of Paul of the Epistles. According to Paul himself (Gal. i. 16--18), after his conversion, he communicated not with flesh and blood, neither went up to Jerusalem to those who were apostles before him, but immediately went away into Arabia, and returned to Damascus, and only after three years he went up to Jerusalem to visit Kephas, and abode with him fifteen days, during which visit none other of the Apostles did he see "save James, the brother of the Lord."
