Patriarch and Council Father
Eutychius occupied the see of Constantinople at a turbulent moment in the Christological controversies of the sixth century. His first patriarchate coincided with Justinian's effort to reconcile divided parties through the condemnation of the Three Chapters, the writings associated with Theodore of Mopsuestia, Theodoret of Cyrus, and Ibas of Edessa. As presiding bishop of the Second Council of Constantinople in 553, Eutychius stood at the center of this work, sharing the first place in the assembly that produced the council's decrees.
His tenure also saw the consecration of the rebuilt Hagia Sophia in 562, the great church of the imperial capital, marking a high point of his early years as patriarch.
