He was an opponent of union with Rome, in contrast to his predecessor John Beccus (1275-1282 A.D.). He was an ascetic and a prayerful person from his childhood. Beloved by his people, Athanasius provoked the displeasure of certain priests by his moral strictness. He withdrew to his monastery on Mount Ganos, where he labored even more austerely than before. The Lord Jesus Christ Himself appeared to him and scolded him gently for leaving his flock to the wolves. When he foretold the day of the earthquake in Constantinople, Emperor Andronicus reinstated him to the patriarchal throne against his will. After that, he again secretly withdrew to the ascetic life. He entered into rest at the age of one hundred. He was clairvoyant and a miracle-worker.
