Cerinthus (Κήρινθος), a heresiarch, who lived in the time of the apostle John, towards the end of the first and at the beginning of the second century. The accounts of the ancients and the opinions of modern writers are equally at variance with respect to him. He was a Jew by nation and religion, who, after having studied in the schools of Alexandria, appeared in Palestine, and spread his errors chiefly in Asia Minor. Our sources of information as to his doctrines are Irenaeus, adv. Haer. 1:26; Eusebius, Hist. Eccl. 3:28; 7:25; Epiphanius, Haer. 28; and Theodoret, Fab. Haer. 2:3 (Opp. tom. 3). Epiphanius makes him to have been one of those Jews who, in their zeal for the law of Moses, troubled the Church of Antioch by insisting on the necessity of the legal ceremonies for the Gentile converts; but in this he is probably mistaken. The account of Irenaeus is that he appeared about the year 88, and was known to St. John, who wrote his Gospel in refutation of his errors. Irenaus, on the authority of Polycarp, narrates that the apostle John, when at Ephesus, going on a certain day to the bath, and finding Cerinthus within, fled from the building, saying, "Let us even be gone, lest the bath should fall to pieces, Cerinthus, that enemy of the truth, being within." Eusebius (3:28), quoting from the presbyter Caius, states that Cerinthus put forth some Revelations, written by himself, as it were by some great apostle, filled with the most monstrous narrations, which he pretended to have received from angels.
As to his peculiar tenets, also, "there is great difference of opinion. Some consider his system to be pure Gnosticism; others a compound of Gnosticism, Judaism, and Christianity. Irenaeus says, 'Cerinthus taught that the world was not made by the supreme God, but by a certain power (Demiurge) separate from Him, and below Him, and ignorant of Him. Jesus he supposed not to be born of a virgin, but to be the son of Joseph and Mary, born altogether as other men are; but he excelled all men in virtue, knowledge, and wisdom. At His baptism, the Christ came down upon Him, from God who is over all, in the shape of a dove; and then He declared to the world the unknown Father, and wrought miracles. At the end, the Christ left Jesus, and Jesus suffered and rose again, but the Christ, being spiritual, was impassible.' Epiphanius says nearly the same, but asserts that Cerinthus taught that the world was made by angels, and that he opposed the apostles in Judaea. It appears that Cerinthus considered Christ an ordinary man, born in the usual way, and devoid of miraculous powers, but distinguished from the rest of the Jews by possessing superior wisdom, so that He was worthy to be chosen as the Messiah; that he knew nothing of his high dignity till it was revealed to Him in His baptism by John, when He was consecrated to the Messiahship, and furnished with the necessary powers for the fulfillment of His office by the descent of the supreme Logos or Spirit from the heavens, which hung over Him like a dove, and at length entered into His heart; that He was then raised to the dignity of the Son of God, began to perform miracles, and even angels were now taught by His revelations; that redemption could not be effected by His sufferings. Jesus, in union with the mighty Spirit of God, could not suffer, but must triumph over all His enemies. The very fact of suffering was assumled to be a proof that the Spirit of God, which had been previously united to Him, was now separated from Him, and had returned to the Father. The sufferings were of the man Jesus, now left to himself. Cerinthus denied also the resurrection of Christ. He adhered in part to Judaism, and considered the Mosaic law binding on Christians. He taught that the righteous would enjoy a paradise of delights in Palestine, and that the man Jesus, through the power of the Logos again coming upon him, as the Messiah, would reign a thousand years" (Farrar, Ecclesiastes Dict. s.v.). It is supposed that Cerinthus and his doctrines are alluded to in John's Gospel. The system of Cerinthus seems to combine Ebionitism with Gnosticism, and the Judaeo-Christian millenarianism.
