The Sixth Ecumenical Council took place in Constantinople, under the auspices of Emperor Constantine IV, from 680 to 681. It was convened to resolve the theological disagreements that arose from different interpretations of the nature of Christ, specifically the controversy surrounding monotheletism, which argued that Christ had two natures but only one will, in contrast to dyotheletism, which asserted that Christ possessed two wills in accordance with his two natures—divine and human. This theological conflict was fueled by ongoing disputes over the nature of Christ that had been developing since the early church and had significant implications for the unity of the church in the Byzantine Empire and beyond.The council consisted of around 170 bishops, who gathered to affirm the dyothelete position, firmly opposing monotheletism, which had been endorsed by various parties including some political leaders within the Byzantine Empire. Important figures in the council included Bishop George of Constantinople, who played a crucial role in the deliberations. The 6th Council is particularly notable for condemning monotheletism and formally excommunicating its proponents, including Patriarch Macarius of Antioch. The council's decisions were encapsulated in the fifth and sixth sessions, where the definition of Christ's nature was articulated in a way intended to preserve the theological integrity and unity of the church.In summary, the Sixth Ecumenical Council was a pivotal moment in Christian history, as it sought to clarify doctrinal ambiguities and reinforce the dual nature of Christ in response to competing theological interpretations. Its outcome played a significant role in shaping the future of Byzantine Christianity and maintaining ecclesiastical authority in the face of political pressures.
