It is not consistent with truth that a man should sacrifice half of his stomach only to God-that he should be sober in drinking, but intemperate in eating. Your belly is your God, your liver is your temple, your paunch is your altar, the cook is your priest, and the fat steam is your Holy Spirit; the seasonings and the sauces are your chrisms, and your belchings are your prophesizing...[such] a grossly- feeding Christian is akin to lions and wolves rather than God. Our Lord Jesus called Himself Truth and not habit.

Thus the connection of the Father in the Son, and of the Son in the Paraclete, produces three coherent Persons, who are yet distinct One from Another. These three are one [thing], not one [Person], as it is said, 'I and my Father are One,' in respect of unity of substance not singularity of number.

Arguments about Scripture achieve nothing but a stomachache and a headache.

You can't undo anything you've already done, but you can face up to it. You can tell the truth. You can seek forgiveness. And then let God do the rest.

Indeed heresies are themselves instigated by philosophy

[Hermogenes] despises God's law in his painting, maintains repeated marriages [almost certainly a reference to remarrying after divorce or perhaps even widowhood, which Tertullian, who became a Montanist, opposed], alleges the law of God in defense of lust [likely same reference], and yet despises it in respect of his art.

He has inhibited discussion by designating admonition as the method of dealing with a heretic- and the first method, too, because he is not a Christian. This is so that he would not seem to require correction again and again and before two or three witnesses as though he were a Christian. He ought to be corrected for the very reason that he is not to be disputed with. In addition, this is said because a controversy over the Scriptures can, clearly, produce no other effect than help to upset either the stomach or the brain.
