“ Then said Appion: “Does it seem to you to be ignorance, that one should observe the customs of his fathers, and judge after the manner of the Greeks?” Then I answered: “It behoves one who desires to be pious not altogether to observe the customs of his fathers; but to observe them if they be pious, and to shake them off if they be impious. For it is possible that one who is the son of an impious father, if he wishes to be pious, should not desire to follow the religion of his father.” ”
