"The nations which have been converted to Christianity are in a way like branches which have been grafted upon Judaism. They were Jews who announced the Gospel to the world, and they were Jews who composed the first Christian community, to which all the other peoples of the world are successively joining themselves. Evidently, therefore, these Jews in becoming Christians did not change their religion, for they only acknowledged the Messias whom they were expecting ; it was the Greeks, the Romans, and the Egyptians, and all the heathen who, in embracing the faith, renounced the worship of idols."
