That there were two different views among the Ebionites as to the birth of Christ is stated frequently by Origen (cf. e.g. Contra Cels. V. 61), but there was unanimity in the denial of his pre-existence and essential divinity, and this constituted the essence of the heresy in the eyes of the Fathers from Irenæus on. Irenæus, as remarked above (note 1), knows of no such difference as Eusebius here mentions: and that the denial of the supernatural birth even in the time of Origen was in fact ordinarily attributed to the Ebionites in general, without a distinction of the two classes, is seen by Origen’s words in his Hom. in Luc. XVII.
