Photian Schism: What Happened

Between 863 and 867 AD, a bitter dispute broke out between the Pope in Rome and the Patriarch of Constantinople, known as the Photian Schism. It centered on Photios, one of the most learned scholars of the Byzantine Empire, who was appointed Patriarch of Constantinople in 858 after the emperor Michael III removed the previous patriarch, Ignatius. Supporters of Ignatius appealed to Pope Nicholas I, who declared Photios's appointment invalid in 863. Photios responded by condemning the Pope and criticizing Western practices, including the Latin addition of the word filioque, meaning and the Son, to the Nicene Creed. Rivalry over missionary work among the Bulgarians, who were being courted by both churches, made tensions worse. In 867, a council in Constantinople declared the Pope deposed. The dispute was eventually settled, and Photios was later reconciled with Rome, but it revealed deep differences in authority, doctrine and practice between the Eastern and Western churches. These tensions continued to grow over the next two centuries and contributed to the Great Schism of 1054.
