The chapter is devoted to the tenure of Methodius as the Patriarch of Constantinople (843–847) and the difficulties he faced in re-organizing the situation of the church after the re-establishment of Orthodoxy, concerning the overthrow of the iconoclast bishops and their replacement by orthodox ones, the opposition of the Studite monks to him and his policy, which resulted in open attack after the transfer of the relics of Theodore the Studite, in January 845, known as the Studite Schism, which led to the subsequent banishment of the Studite leaders Naucratius and Athanasius in 846. The symbol of the Patriarch’s triumph over the Studites was the famous Synodicon of Orthodoxy, composed to commemorate the anniversary of the restoration of the cult of the icons, in February 847, which condemned not only all former heresies, but also all that had been written and said against the saint Patriarchs Tarasius and Nicerphorus, a provision aimed directly against the Studites.
