The same King placed holiness in abstinence from marriage. _Eusebius_ in his Ecclesiastical history [1] tells us, that _Musanus_ wrote a tract against those who fell away to the heresy of the _Encratites_, which was then newly risen, and had introduced pernicious errors; and that _Tatian_, the disciple of _Justin_, was the author thereof; and that _Irenaeus_ in his first book against heresies teaches this, writing of _Tatian_ and his heresy in these words: _A Saturnino & Marcione profecti qui vocantur Continentes, docuerunt non contrahendum esse matrimonium; reprobantes scilicet primitivum illud opificium Dei, & tacite accusantes Deum qui masculum & faeminam condidit ad procreationem generis humani. Induxerunt etiam abstinentiam ab esu eorum quae animalia appellant, ingratos se exhibentes ergo eum qui universa creavit Deum. Negant etiam primi hominis salutem. Atque hoc nuper apud illos excogitatum est, Tatiano quodam omnium primo hujus impietatis auctore: qui Justini auditor, quamdiu cum illo versatus est, nihil ejusmodi protulit. Post martyrium autem illius, ab Ecclesia se abrumpens, doctoris arrogantia elatus ac tumidus, tanquam praestantior caeteris, novam quandam formam doctrinae conflavit: AEonas invisibiles commentus perinde ac Valentinus: asserens quoque cum Saturnino & Marcione, matrimonium nihil aliud esse quam corruptionem ac stuprum: nova praeterea argumenta ad subvertendam Adami salutem excogitans. Haec Irenaeus de Haeresi quae tunc viguit Encratitarum._ Thus far _Eusebius_. But altho the followers of _Tatian_ were at first condemned as hereticks by the name of _Encratites_, or _Continentes_; their principles could not be yet quite exploded: for _Montanus_ refined upon them, and made only second marriages unlawful; he also introduced frequent fastings, and annual, fasting days, the keeping of _Lent_, and feeding upon dried meats. The _Apostolici_, about the middle of the third century, condemned marriage, and were a branch of the disciples of _Tatian_. The _Hierocitae_ in _Egypt_, in the latter end of the third century, also condemned marriage. _Paul_ the _Eremite_ fled into the wilderness from the persecution of _Decius_, and lived there a solitary life till the reign of _Constantine_ the great, but made no disciples. _Antony_ did the like in the persecution of _Dioclesian_, or a little before, and made disciples; and many others soon followed his example.
