7. There was a certain man, Noetus[2] by name, by birth a Smyrnæan. He introduced a heresy from the opinions of Heraclitus. Of which [Noetus], a certain man named Epigonus becomes the minister and pupil, and on his arrival at Rome sowed broadcast the godless doctrine. Whose teaching Cleomenes, by life and manners alien to the Church, confirmed, when he had become his disciple.[3] [Sidenote: p. 426.] At that time Zephyrinus, an ignorant and greedy man, thought that he ruled the Church, and, persuaded by the gain offered, gave leave to those coming to him to learn of Cleomenes.[4] And himself also being in time beguiled, ran into the same errors, his fellow-counsellor and comrade in this wickedness being Callistus, whose life and the heresy invented by him, I shall shortly set forth. The school of these successive [teachers] continued to grow stronger and increased through the help given to it by Zephyrinus and Callistus. Yet we never yielded, but many times withstood them to the face, refuted them, and compelled them perforce to confess the truth. They being ashamed for a season, and being brought by the truth to confession, before long returned to wallowing in the same mire.[5] 8. But since we have pointed out the genealogical succession of these [men], it appears left to us to set forth their evil mode of teaching their doctrines. The opinions of Heraclitus the Obscure being first explained, we shall then make evident the parts of [their doctrines] which are [Sidenote: p. 427.] Heraclitan, but which, perhaps, the present chiefs of the heresy do not know to be those of the Obscure, but think to be those of Christ. Should they meet with these [words], they might, thus being put to shame, cease from their godless blasphemy.[6] And although the teachings of Heraclitus have been before expounded by us in this [our] _Philosophumena_,[7] yet it seems expedient to repeat them now, so that by their closer refutation, those who think they are disciples of Christ may be plainly taught that they are not His, but are those of the Obscure.
