Commemoration of the Holy Fathers of the Sixth Ecumenical Council

The Sixth Ecumenical Council was convened by the emperor Constantine Pogonatos (668-685) at Constantinople in the year 681 to combat the Monothelite heresy. At it 171 holy Fathers were present, who affirmed the doctrine of two wills in Jesus Christ, the divine and the human.

This Council was followed by another Council in the year 691, called the Council in Trullo. This Council addressed certain practical matters, and 102 canons were promulgated.
