Nor was this the doctrine and practice of one school only, which might be ignorant of philosophy; the cultivated minds of the Alexandrian Fathers, who are said to owe so much to Pagan science, certainly showed no gratitude or reverence towards their alleged instructors, but maintained the supremacy of Catholic Tradition. Clement[349:2] speaks of heretical teachers as perverting Scripture, and essaying the gate of heaven with a false key, not raising the veil, as he and his, by means of tradition from Christ, but digging through the Church's wall, and becoming mystagogues of misbelief; "for," he continues, "few words are enough to prove that they have formed their human assemblies later than the Catholic Church," and "from that previously existing and most true Church it is very clear that these later heresies, and others which have been since, are counterfeit and novel inventions."[350:1] "When the Marcionites, Valentinians, and the like," says Origen, "appeal to apocryphal works, they are saying, 'Christ is in the desert;' when to canonical Scripture, 'Lo, He is in the chambers;' but we must not depart from that first and ecclesiastical tradition, nor believe otherwise than as the Churches of God by succession have transmitted to us." And it is recorded of him in his youth, that he never could be brought to attend the prayers of a heretic who was in the house of his patroness, from abomination of his doctrine, "observing," adds Eusebius, "the rule of the Church." Eusebius too himself, unsatisfactory as is his own theology, cannot break from this fundamental rule; he ever speaks of the Gnostic teachers, the chief heretics of his period (at least before the rise of Arianism), in terms most expressive of abhorrence and disgust. 5. The African, Syrian, and Asian schools are additional witnesses; Tertullian at Carthage was strenuous for the dogmatic principle even after he had given up the traditional. The Fathers of Asia Minor, who excommunicated Noëtus, rehearse the Creed, and add, "We declare as we have learned;" the Fathers of Antioch, who depose Paul of Samosata, set down in writing the Creed from Scripture, "which," they say, "we received from the beginning, and have, by tradition and in custody, in the Catholic and Holy Church, until this day, by succession, as preached by the blessed Apostles, who were eye-witnesses and ministers of the Word."[350:2] 6.
