1. As the churches throughout the world were now shining like the most brilliant stars, and faith in our Saviour and Lord Jesus Christ was flourishing among the whole human race, the demon who hates everything that is good, and is always hostile to the truth, and most bitterly opposed to the salvation of man, turned all his arts against the Church. In the beginning he armed himself against it with external persecutions.
2. But now, being shut off from the use of such means, he devised all sorts of plans, and employed other methods in his conflict with the Church, using base and deceitful men as instruments for the ruin of souls and as ministers of destruction. Instigated by him, impostors and deceivers, assuming the name of our religion, brought to the depth of ruin such of the believers as they could win over, and at the same time, by means of the deeds which they practiced, turned away from the path which leads to the word of salvation those who were ignorant of the faith.
3. Accordingly there proceeded from that Menander, whom we have already mentioned as the successor of Simon, a certain serpent-like power, double-tongued and two-headed, which produced the leaders of two different heresies, Saturninus, an Antiochian by birth, and Basilides, an Alexandrian. The former of these established schools of godless heresy in Syria, the latter in Alexandria.
4. Irenæus states that the false teaching of Saturninus agreed in most respects with that of Menander, but that Basilides, under the pretext of unspeakable mysteries, invented monstrous fables, and carried the fictions of his impious heresy quite beyond bounds.
5. But as there were at that time a great many members of the Church who were fighting for the truth and defending apostolic and ecclesiastical doctrine with uncommon eloquence, so there were some also that furnished posterity through their writings with means of defense against the heresies to which we have referred.
6. Of these there has come down to us a most powerful refutation of Basilides by Agrippa Castor, one of the most renowned writers of that day, which shows the terrible imposture of the man.
7. While exposing his mysteries he says that Basilides wrote twenty-four books upon the Gospel, and that he invented prophets for himself named Barcabbas and Barcoph, and others that had no existence, and that he gave them barbarous names in order to amaze those who marvel at such things; that he taught also that the eating of meat offered to idols and the unguarded renunciation of the faith in times of persecution were matters of indifference; and that he enjoined upon his followers, like Pythagoras, a silence of five years.
8. Other similar things the above-mentioned writer has recorded concerning Basilides, and has ably exposed the error of his heresy.
9. Irenæus also writes that Carpocrates was a contemporary of these men, and that he was the father of another heresy, called the heresy of the Gnostics, who did not wish to transmit any longer the magic arts of Simon, as that one had done, in secret, but openly. For they boasted -- as of something great -- of love potions that were carefully prepared by them, and of certain demons that sent them dreams and lent them their protection, and of other similar agencies; and in accordance with these things they taught that it was necessary for those who wished to enter fully into their mysteries, or rather into their abominations, to practice all the worst kinds of wickedness, on the ground that they could escape the cosmic powers, as they called them, in no other way than by discharging their obligations to them all by infamous conduct.
10. Thus it came to pass that the malignant demon, making use of these ministers, on the one hand enslaved those that were so pitiably led astray by them to their own destruction, while on the other hand he furnished to the unbelieving heathen abundant opportunities for slandering the divine word, inasmuch as the reputation of these men brought infamy upon the whole race of Christians.
11. In this way, therefore, it came to pass that there was spread abroad in regard to us among the unbelievers of that age, the infamous and most absurd suspicion that we practiced unlawful commerce with mothers and sisters, and enjoyed impious feasts.
12. He did not, however, long succeed in these artifices, as the truth established itself and in time shone with great brilliancy.
13. For the machinations of its enemies were refuted by its power and speedily vanished. One new heresy arose after another, and the former ones always passed away, and now at one time, now at another, now in one way, now in other ways, were lost in ideas of various kinds and various forms. But the splendor of the catholic and only true Church, which is always the same, grew in magnitude and power, and reflected its piety and simplicity and freedom, and the modesty and purity of its inspired life and philosophy to every nation both of Greeks and of Barbarians.
14. At the same time the slanderous accusations which had been brought against the whole Church also vanished, and there remained our teaching alone, which has prevailed over all, and which is acknowledged to be superior to all in dignity and temperance, and in divine and philosophical doctrines. So that none of them now ventures to affix a base calumny upon our faith, or any such slander as our ancient enemies formerly delighted to utter.
15. Nevertheless, in those times the truth again called forth many champions who fought in its defense against the godless heresies, refuting them not only with oral, but also with written arguments.
