Berillus the bishop.
Beryllus, 2473 bishop of Bostra in Arabia, after he had ruled the church gloriously 2474 for a little while, finally lapsed into the heresy which denies that Christ existed before the incarnation. Set right by Origen, he wrote various short works, especially letters, in which he thanks Origen. The letters of Origen to him, are also extant, and a dialogue between Origen and Beryllus as well, in which heresies are discussed. He was distinguished during the reign of Alexander, son of Mammaea, and Maximinus and Gordianus, who succeeded him in power.
