᾽Εγκρατεῖς, a word meaning “temperate” or “continent.” These Encratites were heretics who abstained from flesh, from wine, and from marriage, not temporarily but permanently, and because of a belief in the essential impurity of those things. They are mentioned also by Hippolytus (Phil. VIII. 13), who calls them ἐγκρατῖται; by Clement of Alexandria (Pæd. II. 2, Strom. I. 15, &c.), who calls them ἐγκρατηταί; by Epiphanius (Hær. 47), who agrees with Hippolytus in the form of the name, and by others. The Encratites whom Irenæus describes seem to have constituted a distinct sect, anti-Jewish and Gnostic in its character. As described by Hippolytus they appear to have been mainly orthodox in doctrine but heretical in their manner of life, and we may perhaps gather the same thing from Clement’s references to them. It is evident, therefore, that Irenæus and the others are not referring to the same men. So Theodoret, Hær. Fab. I. 21, speaks of the Severian Encratites; but the Severians, as we learn from this chapter of Eusebius and from Epiphanius (Hær. XLV.), were Ebionitic and anti-Pauline in their tendencies—the exact opposites, therefore, of the Encratites referred to by Irenæus. That there was a distinct sect of Encratites of the character described by Irenæus cannot be denied, but we must certainly conclude that the word was used very commonly in a wider sense to denote men of various schools who taught excessive and heretical abstinence. Of course the later writers may have supposed that they all belonged to one compact sect, but it is certain that they did not. As to the particular sect which Irenæus describes, the statement made by Eusebius at the close of the preceding chapter is incorrect, if we are to accept Irenæus’ account. For the passage quoted in this chapter states that they sprung from Marcion and Saturninus, evidently implying that they were not founded by Tatian, but that he found them already in existence when he became heretical. It is not surprising, however that his name should become connected with them as their founder—for he was the best-known man among them. That the Encratites as such (whether a single sect or a general tendency) should be opposed by the Fathers, even by those of ascetic tendencies, was natural. It was not always easy to distinguish between orthodox and heretical asceticism, and yet there was felt to be a difference. The fundamental distinction was held by the Church—whenever it came to self-consciousness on the subject—to lie in the fact that the heretics pronounced the things from which they abstained essentially evil in themselves, thus holding a radical dualism, while the orthodox abstained only as a matter of discipline. The distinction, it is true, was not always preserved, but it was this essentially dualistic principle of the Encratites which the early Fathers combated; it is noticeable, however, that they do not expend as much vigor in combating it as in refuting errors in doctrine. In fact, they seem themselves to have been somewhat in doubt as to the proper attitude to take toward these extreme ascetics.
