It has been supposed that Muhammad derived many of his notions concerning Christianity from Gnosticism, and that it is to the numerous gnostic sects the Koran alludes when it reproaches the Christians with having "split up their religion into parties." But for Muhammad thus to have confounded Gnosticism with Christianity itself, its prevalence in Arabia must have been far more universal than we have any reason to believe it really was. In fact, we have no historical authority for supposing that the doctrines of these heretics were taught or professed in Arabia at all. It is certain, on the other hand, that the Basilidans, Valentinians, and other gnostic sects had either died out, or been reabsorbed into the orthodox Church, towards the middle of the fifth century, and had disappeared from Egypt before the sixth. It is nevertheless possible that the gnostic doctrine concerning the Crucifixion was adopted by Muhammad as likely to reconcile the Jews to Islam, as a religion embracing both Judaism and Christianity, if they might believe that Jesus had not been put to death, and thus find the stumbling-block of the atonement removed out of their path. The Jews would in this case have simply been called upon to believe in Jesus as being what the Koran represents him, a holy teacher, who, like the patriarch Enoch or the prophet Elijah, had been miraculously taken from the earth. But, in all other respects, the sober and matter-of-fact statements of the Koran relative to the family and history of Jesus, are altogether opposed to the wild and fantastic doctrines of Gnostic emanations, and especially to the manner in which they supposed Jesus, at his Baptism, to have been brought into union with a higher nature. It is quite clear that Muhammad borrowed in several points from the doctrines of the Ebionites, Essenes, and Sabeites. Epiphanius (H‘r. x.) describes the notions of the Ebionites of Nabath‘a, Moabitis, and Basanitis with regard to Adam and Jesus, almost in the very words of Sura iii. 52. He tells us that they observed circumcision, were opposed to celibacy, forbad turning to the sunrise, but enjoined Jerusalem as their Kebla (as did Muhammad during twelve years), that they prescribed (as did the Sabeites), washings, very similar to those enjoined in the Koran, and allowed oaths (by certain natural objects, as clouds, signs of the Zodiac, oil, the winds, etc.), which we find adopted in the Koran. These points of contact with Islam, knowing as we do Muhammad's eclecticism, can hardly be accidental.
