Council of 867

The Council of 867 was an important religious gathering held in Constantinople to address issues within the Eastern Orthodox Church, particularly concerning heresies and church doctrine. It aimed to clarify and reinforce orthodox beliefs, especially against the Monothelite controversy, which questioned whether Christ had one or two wills. The council reaffirmed the church’s teachings that Christ has two complete natures—divine and human—and established guidelines to maintain doctrinal unity. This assembly helped strengthen church authority and provided clarity on Christ’s nature, influencing Christianity’s development in the Eastern Roman Empire.
