Clement of Alexandria : Now it is adultery, if one, abandoning the ecclesiastical and true knowledge, and the persuasion respecting God, accedes to false and incongruous opinion, either by deifying any created object, or by making an idol of anything that exists not, so as to overstep, or rather step from, knowledge. And to the Gnostic false opinion is foreign, as the true belongs to him, and is allied with him. Wherefore the noble apostle calls one of the kinds of fornication, idolatry, in following the prophet, who says: "[My people] hath committed fornication with stock and stone. They have said to the stock, Thou art my father; and to the stone, Thou hast begotten me." — The Stromata Book 6 Jerome : So that poisoning and sorcery might not appear to be condoned in the New Testament, they are included among the works of the flesh. This happens when people love and are loved through magical arts. — EPISTLE TO THE Galatians 3.5.19-21 Jerome : It often happens that dissensions arise in the interpretation of Scripture, from which heresies, here numbered among the works of the flesh, boil over. For if "the wisdom of the flesh is at enmity with God" (and all false doctrines, being repugnant to God, are at enmity), heresies also, being at enmity with God, are consequently included among the works of the flesh. — EPISTLE TO THE Galatians 3.5.19-21 Oecumenius : "enmities." The unjust. For there are also just enmities, those arising from faithfulness. For he says that if it were possible for you to be at peace with all people, it is clear that there are times when this is not possible. "jealousy." For one must not be jealous, but rejoice with those who rejoice, and weep with those who weep. "rivalries." As in quarrels arising from conflict. — Commentary on Galatians Tertullian : On this point, however, we dwell no longer, since it is the same Paul who, in his Epistle to the Galatians, counts "heresies" among "the sins of the flesh," who also intimates to Titus, that "a man who is a heretic" must be "rejected after the first admonition," on the ground that "he that is such is perverted, and committeth sin, as a self-condemned man. — The Prescription Against Heretics Theodoret of Cyrus : Now it is clear that idolatry and sorcery and things of that kind belong not to the flesh but to the soul. In fact it is not the flesh that he is condemning but the wayward mind. — EPISTLE TO THE Galatians 5.19-21
