in ecclesiastical writers, were ancient sectaries, who disturbed the peace of the church in the beginning of the third century; thus 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: on which account his adherents bore an implacable hatred to their own flesh; which sometimes carried them so far as to kill themselves. They were also called TATIANITES, and made a branch of the EXORCITAE.
