Editing Theodore the Studite (section)

===Conflict with Nikephoros===
Emperor Nikephoros soon requested that his new patriarch rehabilitate the priest Joseph, who had officiated at the wedding of Constantine and Theodote, possibly because Joseph had aided in the peaceful resolution of the revolt of [[Bardanes Tourkos]]. In 806, the Patriarch Nikephoros convened a [[synod]] to address the case, at which Theodore was present. The Synod decided to readmit Joseph to the priesthood, a decision to which Theodore did not at the time object.<ref>{{harvnb|Pratsch|1998|pp=147–149}}.</ref>

Therefore, relations between the Studite Abbot and the Patriarch appear to have been initially untroubled, an impression which is reinforced by the choice (806/807) of Theodore's brother, Joseph, as Archbishop of Thessaloniki.<ref>{{harvnb|Pratsch|1998|pp=151–153}}.</ref> However, soon after this ordination, perhaps in 808, Theodore began to express his unwillingness to associate with the rehabilitated priest Joseph, or for that matter with anyone else who knowingly associated with him, as he held the rehabilitation to be uncanonical. As in the first dispute over the priest Joseph, the extension of this refusal beyond Joseph to those who associated with him included implicitly the patriarch and the emperor himself.<ref>{{harvnb|Pratsch|1998|pp=153–157}}.</ref>

Early in 808, Theodoros offered in a series of letters to explain his position to the emperor, and furthermore to perform the customary [[proskynesis]] at his feet, which offer Nikephoros declined, instead setting off for the summer military campaign.<ref>{{harvnb|Pratsch|1998|pp=159–161}}.</ref> In the winter of the same year, Theodore's brother Joseph visited him in Constantinople, but refused to attend the Christmas mass in Hagia Sophia, at which the emperor, the patriarch, and the priest Joseph would have been present. As a result, he was stripped of his archbishopric.<ref>{{harvnb|Pratsch|1998|pp=162–163}}.</ref> At around the same time a small military division was dispatched to the Stoudios Monastery to arrest Theodore, Joseph, and Platon.<ref>{{harvnb|Pratsch|1998|p=167}}.</ref> A synod was then held in January of 809, at which Theodore and his followers were anathematized as schismatic.<ref>{{harvnb|Pratsch|1998|pp=170–171}}.</ref> Theodore, Joseph, and Platon were thereafter banished to the [[Princes' Islands]]: Theodore to [[Heybeliada|Chalke]], Joseph to [[Kınalıada|Prote]], and Platon to [[Sivriada|Oxeia]].<ref>{{harvnb|Pratsch|1998|p=173}}.</ref>

Theodore maintained an extensive literary activity in exile, writing numerous letters to correspondents including his brother, various Studite monks, influential family members, and even [[Pope Leo III]]. He also continued to compose catechisms for the Studite congregation, as well as a number of poems.<ref>{{harvnb|Pratsch|1998|pp=175–176}}.</ref>
