Hippolytus of Rome

Others, however, styling themselves Encratites, acknowledge some things concerning God and Christ in like manner with the Church. In respect, however, of their mode of life, they pass their days inflated with pride. They suppose, that by meats they magnify themselves, while abstaining from animal food, (and) being water-drinkers, and forbidding to marry, and devoting themselves during the remainder of life to habits of asceticism. But persons of this description are estimated Cynics rather than Christians, inasmuch as they do not attend unto the words spoken against them through the Apostle Paul. Now he, predicting the novelties that were to be hereafter introduced ineffectually by certain (heretics), made a statement thus: "The Spirit speaketh expressly, In the latter times certain will depart from sound doctrine, giving heed to seducing spirits and doctrines of devils, uttering falsehoods in hypocrisy, having their own conscience seared with a hot iron, forbidding to marry, to abstain from meats, which God has created to be partaken of with thanksgiving by the faithful, and those who know the truth; because every creature of God is good, and nothing to be rejected which is received with thanksgiving; for it is sanctified by the word of God and prayer." This voice, then, of the blessed Paul, is sufficient for the refutation of those who live in this manner, and plume themselves on being just; (and) for the purpose of proving that also, this (tenet of the Encratites) constitutes a heresy.
