Beryllus bishop of Bostra, in Arabia, 3d century. Our only definite knowledge of him is derived from a passage in Eusebius (Hist. Eccl. 6, 33), which says that he held that "our Lord did not exist, in the proper sense of existence, before he dwelt among men; neither had he a proper divinity, only that divinity which dwelt in him from the Father." Eusebius goes on to say that Origen, by discussion with Beryllus, brought him back to the faith. There has been much discussion of late as to the real nature of the heresy of Beryllus. See an article of Schleiermacher, translated in the Biblical Repository, 6, 14; see also Neander, Ch. History, 1, 593 sq.; Dorner, Doctrine of the Person of Christ, div. 1, vol. 2, p. 35.
