FOURTH CENTURY. Presbyter of Alexandria. The first to sign the deposition of Arius in an encyclical of Alexander* of Alexandria about 321, Colluthus was accused by the latter of indiscretion by 324. A synod of Alexandria in the same year under Hosius deposed Ischyras, a presbyter ordained by Colluthus, and received him back into communion as a layman. By 339 an Egyptian synod affirmed that Colluthus had died as a presbyter and that his ordinations were invalid. No reason is apparent for his unauthorized ordinations. Later Philastrius (d. c.397), followed by Augustine, charged Colluthus with the heresy of denying that God made evil.
