in ecclesiastical writers, were ancient secraries, who disturbed the peace of the church in the beginning of the third century, and who were so called from their founder Patricius, preceptor of a Marcionite called Symmachus. His distinguishing tenet was, that the substance of the flesh is not the work of God, but that of the devil; and on this account his adherents bore an implacable hatred to their own flesh, which they sometimes carried so far as to kill themselves. They were also called Tatianites, and formed a branch of the Eucratites.
