Atticus supported the Macedonian heresy (i.e., the Holy Spirit is not God), opposed Saint John Chrysostom, and worked against him at the Council of Oak in 405. When John was exiled from Constantinople, Atticus assumed the bishopric in 406. He eventually realized his error, repented his opposition, and submitted to Pope Innocent I‘s rulings. He remained as bishop, but a virtuous and orthodox one, and an opponent of heretics.
