The Mosaic account of the creation and fall of man was treated with profane derision by the Gnostics, who would not listen with patience to the repose of the Deity after six days’ labour, to the rib of Adam, the garden of Eden, the trees of life and of knowledge, the speaking serpent, the forbidden fruit, and the condemnation pronounced against human kind for the venial offence of their first progenitors. The God of Israel was impiously represented by the Gnostics as a being liable to passion and to error, capricious in his favour, implacable in his resentment, meanly jealous of his superstitious worship, and confining his partial providence to a single people and to this transitory life. In such a character they could discover none of the features of the wise and omnipotent father of the universe. They allowed that the religion of the Jews was somewhat less criminal than the idolatry of the Gentiles; but it was their fundamental doctrine that the Christ whom they adored as the first and brightest emanation of the Deity appeared upon earth to rescue mankind from their various errors, and to reveal a new system of truth and perfection. The most learned of the fathers, by a very singular condescension, have imprudently admitted the sophistry of the Gnostics. Acknowledging that the literal sense is repugnant to every principle of faith as well as reason, they deem themselves secure and invulnerable behind the ample veil of allegory, which they carefully spread over every tender part of the Mosaic dispensation.
