(fl. c. A.D. 230), a prominent Christian teacher at Rome, who held Adoptianist (see ADOPTIANISM), or humanitarian views, of the same type as his elder contemporaries the Theodotians, though perhaps asserting more definitely than they the superiority of Christ to the prophets in respect of His supernatural birth and sinlessness. He was excommunicated by Zephyrinus, despite his remarkable claim that all that bishop's predecessors in the see of Rome had held the humanitarian position. (See also MONARCHIANISM.)
