It was likely that they should prefer it, for it began at the baptism, and this event it stated, or was thought to state, was the beginning of the Gospel; to Docetic minds an admission, an assertion rather, that all that preceded was of no importance; Jesus was but a man as are other men, till the plenitude of the Spirit descended on him. The early history might be matter of curiosity, but not of edification. That matter is evil is a doctrine which in the East has proved the fertile mother of heresies. Those infected with this idea—and it is an idea, like Predestinarianism, which, when once accepted and assimilated, pervades the whole tissue of belief and determines its form and complexion—could not acknowledge frankly and with conviction the dogma of the Incarnation. That God should have part with matter, was as opposed to their notions as a concord of light with darkness. Carried by the current setting strongly that way, they found themselves landed in Christianity. They set to work at once to mould Christianity in accordance with their theory of the inherent evil in matter. Christ, an emanation from the Pleroma, the highest, purest wave that swept from the inexhaustible fountain of Deity, might overshadow, but could not coalesce with, the human Jesus. The nativity and the death of our Lord were repugnant to their consciences. They evaded these facts by considering that he was born and died as man, but that the bright overshadowing cloud of the Divinity, of the Christ, reposed on him for a brief period only; it descended at the baptism, it withdrew before the passion. Such were the party—they were scarcely yet a sect—who used the Gospel of St. Peter. Was this Gospel a corrupted edition of St. Mark? Probably not. We have not much ground on which to base an opinion, but there is just sufficient to make it likely that such was not the case. To the Docetae, the nativity of our Lord was purely indifferent; it was not in their Gospel; that it was miraculous they would not allow. To admit that Christ was the Son of God when born of Mary, was to abandon their peculiar tenets. It was immaterial to them whether Jesus had brothers and sisters, or whether James and Jude were only his cousins. The Canonical Gospels speak of the brothers and sisters of Christ, and we are not told that they were not the children of Mary.(376) When the Memorabilia were committed to writing, there was no necessity for doing so. The relationship was known to every one. Catholics, maintaining the perpetual virginity of the mother of Jesus, asserted that they were children of Joseph by a former wife, or cousins. The Gospel of St. Peter declared them to be the children of Joseph by an earlier marriage. Origen says, “There are persons who assure us that the brothers of Jesus were the sons whom Joseph had by his first wife, before he married Mary. They base their opinion on either the Gospel entitled the Gospel of Peter, or on the Book of James (the Protevangelium).”(377)
