up to David, did so according to the genealogy given in the Gospel of St. Mathew, and therefore they would not accept what was said respecting the miraculous conception, affirming that it was apocryphal, and in obvious contradiction to the genealogy in which our Saviour's line was traced up through Joseph, who, it would thus appear, was not his father. They are to be considered as the national or patriotic party. [Sidenote: Causes of the arrest of Jewish conversion.] Two causes seem to have been concerned in arresting the spread of conversion among the Jews: the first was their disappointment as respects the temporal power of the Messiah; the second, the prominence eventually given to the doctrine of the Trinity. Their jealousy of anything that might touch the national doctrine of the unity of God became almost a fanaticism. Judaic Christianity may be said to have virtually ended with the destruction of Jerusalem by the Romans; its last trace, however, was the dispute respecting Easter, which was terminated by the Council of Nicea. The conversion of the Jews had ceased before the reign of Constantine. [Sidenote: Gnostic Christianity.] The second form, Gnostic Christianity, had reached its full development within a century after the death of Christ; it maintained an active influence through the first four centuries, and gave birth, during that time, to many different subordinate sects. It consisted essentially in ingrafting Christianity upon Magianism. It made the Saviour an emanated intelligence, derived from the eternal, self-existing mind; this intelligence, and not the Man-Jesus, was the Christ, who thus, being an impassive phantom, afforded to Gnosticism no idea of an expiatory sacrifice, none of an atonement. It was arrested by the reappearance of pure Magianism in the Persian empire under Ardeschir Babhegan; not, however, without communicating to orthodox Christianity an impression far more profound than is commonly supposed, and one of which indelible traces may be perceived in our day.
