Acacius of Constantinople

Acacius of Constantinople served as the patriarch of Constantinople from four hundred seventy-two to four hundred eighty-nine. He was a prominent figure in the Eastern Orthodox Church, recognized as one of the first prelates in the region. His tenure was marked by his ambitious involvement in the Chalcedonian controversy, which sought to address the theological divisions within Christianity.

Despite his intentions to heal these divisions, Acacius's efforts led to the Acacian schism, resulting in his condemnation by the Chalcedonian churches. His controversial actions included advising the Byzantine emperor Zeno to issue the Henotikon Edict in four hundred eighty-two. This edict condemned Nestorius of Constantinople and Eutyches, accepted the Twelve Chapters of Cyril of Alexandria, and notably ignored the Chalcedonian Definition.

The Henotikon was intended to resolve the conflicts surrounding the Council of Chalcedon, but it ultimately failed to achieve its goal. Pope Felix III viewed Acacius's disregard for Chalcedon and his predecessor, Pope Leo I, as a significant affront to the prestige of the Holy See. This led to Acacius being condemned and deposed by Pope Felix III, an action that Acacius met with contempt, resulting in a schism that persisted beyond his death.

The schism continued throughout the tumultuous reign of the Byzantine emperor Anastasius I Dicorus and was only resolved by emperor Justin I under Pope Hormisdas in five hundred nineteen. In the Coptic Orthodox Church, Acacius is celebrated for his contributions, with the Departure of St. Acacius, Patriarch of Constantinople, commemorated on the thirtieth of the Coptic month of Hathor.
