In 595, the controversy was again rife about the title of Ecumenical Patriarch. Gregory wrote to his legate Sabinianus forbidding him to communicate with John. In the case of a presbyter named Athanasius, accused of being to some extent a Manichean, and condemned as such, Gregory tried to show that the accuser was himself a Pelagian, and that by the carelessness, ignorance, or fault of John IV, the Nestorian council of Ephesus had actually been mistaken for the Orthodox Council of Ephesus.
