Gennadius. Lives of Illustrious Men 14

Audentius, bishop of Spain, wrote a book against the Manicheans, Sabellians and Arians and very particularly against the Photinians who are now called Bonosiacians. This book he entitled On faith against heretics, and in it he showed the Son to have been coeternal with the Father and that He did not receive the beginning of his deity from God the Father, at the time when conceived by the act of God, he was born of the Virgin Mary his mother in true humanity.
