"For Peter was probably in fact and effect the bridge-man (pontifex maximus!) who did more than any other to hold together the diversity of first-century Christianity. James the brother of Jesus, and Paul of Tarsus, the two other most prominent leading figures in first-century Christianity, were too much identified with their respective "brands" of Christianity, at least in the eyes of Christians at the opposite ends of this particular spectrum. But Peter, as shown particularly by the Antioch episode in Galatians 2, had both a care to hold firm to his Jewish heritage – which Paul lacked – and an openness to the demands of developing Christianity, which James lacked. John might have served as a figure of the center holding together the extremes, but if the writings linked with his name are at all indicative of his own stance, he was too much of an individualist to provide such a rallying point. Others could link the developing new religion more firmly to its founding events and to Jesus himself. But none of them, including the rest of the twelve, seem to have played any role of continuing significance for the whole sweep of Christianity—though James the brother of John might have proved an exception had he been spared."
