Tatian, however, although being himself a disciple of Justinus the Martyr, did not entertain similar opinions with his master. But he attempted (to establish) certain novel (tenets), and affirmed that there existed certain invisible Æons. And he framed a legendary account (of them), similarly to those (spoken of) by Valentinus. And similarly with Marcion, he asserts that marriage is destruction. But he alleges that Adam is not saved on account of his having been the author of disobedience. And so far for the doctrines of Tatian.
