Photinus was a Galatian, who became Bishop of Sirmium (Mitrovitz in Slavonia) in the fourth century. He taught that Jesus Christ did not exist before His mother Mary, but was begotten of her by Joseph. The man Jesus, of a reasonable soul and human flesh subsisting, was enlightened and guided by the influence of the Logos, or Divine Reason, whereby He became the Son of God, preeminent over all other prophets and teachers.
