“Paul is the most luminous personality in the history of primitive Christianity, and yet opinions differ widely as to his true significance. Only a few years ago we had a leading Protestant theologian asserting that Paul’s rabbinical theology led him to corrupt the Christian religion. Others, conversely, have called him the real founder of that religion. But in the opinion of the great majority of those who have studied him, the true view is that he was the one who understood the Master and continued his work. This opinion is borne out by the facts…As we cannot want to be wiser than history, which knows him only as Christ’s missionary, and as his own words clearly attest what his aims were and what he was, we regard him as Christ’s disciple, as the apostle who not only worked harder but also accomplished more than all the rest put together.”
