§ 131. Tatian and the Encratites.
Schaff provides a relatively extensive, lightly annotated bibliography for Tatian (Schaff 2014, Loc. 18541). Tatian was a convert of Justin Martyr but later became a Gnostic. He rejected Jewish roots of the Christian faith and held to a severe asceticism, including a rejection of marriage and other pleasures. Schaff observes that his scholarly work, most notably a harmony of the Gospels and a treatise speaking against Gentiles do not seem to be Gnostic in nature (Schaff 2014, Loc. 18565). His followers, known as the Encratites, rejected meat, wine, and marriage, not for pragmatic purposes, but because they viewed those things as intrinsically evil (Schaff 2014, Loc. 18571). Schaff is clear that the rejection of wine or substitution of other things for it is not appropriate in communion.
