The Sixth Ecumenical Council was

Commemorated on January 23

The Sixth Ecumenical Council was convened by the emperor Constantine Pogonatos (668-685) at Constantinople in the year 681 concerning the Monothelite heresy. At it were present 171 holy fathers, who affirmed the confession of faith concerning the two wills in Jesus Christ – the Divine and the human. Continuing the work, this Council was followed by another Council in the year 691 in the imperial palaces, called the Council of Trullo. At this Council was made an examination of practical matters as to their canonical propriety, and 102 rule-canons were established.
