Interesting Dialogs

It's a bit dated, but this report on efforts to unite 'the two families of the Orthodox Church' is very interesting. Apparently the Council of Chalcedon, perhaps due to politicized maneuvers, created a split in the late 5th century. The Coptic Orthodox Church, however, maintains that it never believed in Monophysitism. Also found this interesting list of reports about official dialogs with other brethren. The list does not seem to include the Join Declaration on the Doctrine of Justification by the Lutheran World Federation and the Catholic Church.
