Patriarch Macedonius II of Constantinople

“Macedonius declared, when desired by the Emperor Anastasius to condemn the Council of Chalcedon, that ‘such a step without an Ecumenical Synod presided over by the Pope of Rome is impossible.’ ” (Macedonius, Patriarch of Constantinople, Patr. Graec. 108: 360a [A.D. 466–516]).
