Aristocritus (Greek, Ancient (to 1453);: Ἀριστόκριτος) was a Christian, Platonist writer of the fifth century who was the author of a work titled Theosophy, ostensibly about oracles, but in which he expressed a controversial syncretic belief that Christianity, Judaism, and Manichaeism were all basically the same.[1] [2] This belief caused him to be condemned by Zacharias Rhetor as well as in various later Byzantine texts. He is known to us primarily by his mention in a list of medieval anathemas, written around the year 1000, known as the Long Anathema, primarily aimed at Manichaeans. His identification as a Manichaean is however considered somewhat dubious, as he was known to write uncharitable things about Mani himself.[3]
Theosophy is a lost work, though some scholars have identified this with the so-called Tübingen Theosophy.[4] Other scholars disagree that these are the same works.[2] [5]
