Council of Hagia Sophia, Constantinople

1341 - Council of Haghia Sophia (Ninth Ecumenical) convened by Roman Emperor Andronicus III, presided over by Ecumenical Patriarch John Calecas, and attended by the Patriarchs of Alexandria, Antioch and Jerusalem, and several bishops and abbots, including St. Gregory Palamas. This council condemns Barlaam of Calabria, who believes the light of Mt. Tabor is created, and who criticizes the mystical Jesus Prayer as a supposed practice of the Bogomils, and charges it for not proclaiming Christ as God. Emperor Andronicus dies after the council's first session, and the second session is convened by de facto Roman Emperor John VI Cantacuzene, and presided over by Patriarch John Calecas. This council condemns Acindynus, who takes the opposite extreme to Barlaam of Calabria, believing that the light of Mt. Tabor is the divine essence itself, rather than God's uncreated grace and energy, distinct from His divine essence.
