1 Timothy 4:3

"Well," saith one, "and what dost thou require us to do? to occupy the mountains, and become monks?" Why it is this which makes me sigh, that ye think them alone to be properly concerned with decency and chastity; and yet assuredly Christ made His laws common to all. Thus, when He saith, "if any one look on a woman to lust after her," He speaks not to the solitary, but to him also that hath a wife; since in fact that mount was at that time filled with all kinds of persons of that description. Form then in thy mind an image of that amphitheatre, and hate thou this, which is the devil's. Neither do thou condemn the severity of my speech. For I nether "forbid to marry," nor hinder thy taking pleasure; but I would have this be done in chastity, not with shame, and reproach, and imputations without end. I do not make it a law that you are to occupy the mountains and the deserts, but to be good and considerate and chaste, dwelling in the midst of the city. For in fact all our laws are common to the monks also, except marriage; yea rather, even with respect to this, Paul commands us to put ourselves altogether on a level with them; saying, "For the fashion of this world passeth away:" that "they that have wives be as though they had none."

"Forbidding to marry, and commanding to abstain from meats." Why then has he mentioned no other heresies? Though not particularized, they are implied by the expressions of "seducing spirits and doctrines of demons." But he did not wish to instill these things into the minds of men before the time; but that which had already commenced, the case of meats, he specifies. "Which God hath created to be received with thanksgiving of them which believe and know the truth." Why did he not say, by the unbelievers too? How by the unbelievers, when they exclude themselves from them by their own rules? But is not luxury forbidden? Certainly it is. But why? if good things are created to be received. Because He created bread, and yet too much is forbidden; and wine also, and yet excess is forbidden; and we are not commanded to avoid dainties as if they were unclean in themselves, but as they corrupt the soul by excess. It is then the last time. For "in the latter times," he says, "some shall depart from the faith." "Forbidding to marry." And do not we forbid to marry? God forbid. We do not forbid those who wish to marry, but those who do not wish to marry, we exhort to virginity. It is one thing to forbid, and another to leave one to his own free choice. He that forbids, does it once for all, but he who recommends virginity as a higher state, does not forbid marriage, because he prefers virginity. "Forbidding to marry," he says, "and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth." It is well said, "who know the truth." The former things then were a type. For nothing is unclean by nature, but it becomes so through the conscience of him that partakes of it. And what was the object of the prohibition of so many meats? To restrain excessive luxury. But had it been said, "eat not for the sake of luxury," it would not have been borne. They were therefore shut up under the necessity of the law, that they might abstain from the stronger principle of fear. The fish was not forbidden, though it was manifestly more unclean than the swine. But they might have learned how pernicious luxury was from that saying of Moses, "Jeshurun waxed fat, and kicked." (Deut. xxxii. 15) Another cause of these prohibitions might be, that being straitened for other food, they might be reduced to slaughter sheep and oxen; he therefore restrained them from other things, on account of Apis and the calf, which was an abomination, ungrateful, polluted, and profane.
