Council of Chalcedon

The Council of Chalcedon was a church council held from October 8 to November 1, AD 451, at Chalcedon. The council is numbered as the fourth ecumenical council by the Catholic Church, the Eastern Orthodox Church, and most Protestants. Oriental Orthodoxy Churches do not agree with the conduct and the proceedings of the Council, commonly calling it "Chalcedon, the Ominous".

Quotes

 * God wants us to love him eternally with our whole hearts – not in such a way as to injure or weaken our earthly love, but to provide a kind of cantus firmus to which the other melodies of life provide the counterpoint. ...

The two are ‘undivided and yet distinct’, in the words of the Chalcedonian Definition, like Christ in his divine and human natures.
 * Dietrich Bonhoeffer, Letters and Papers from Prison (1967), p. 303
