Episcopal Ministry under Ottoman Rule
As bishop, Athanasius governed his metropolis during the hardships of the Ottoman occupation of the Peloponnese. The sources remember him as a shepherd attentive both to the worship of the Church and to the material sufferings of his people. He arranged for the repair and maintenance of churches and supported the monasteries of his region, which served as centers of education and charity.
He is credited with establishing schools for the training of priests and with waiving the customary episcopal fees, easing the burden on his flock. His charitable care extended to orphans, widows, the needy, the elderly, and the persecuted and aggrieved. He himself is described as living an ascetic life of fasting, vigil, and prayer.
