First a union must occur, as described in Beyond Dialogue: The Quest for Eastern and Oriental Orthodox Unity Today, Rev John H Erickson, Dean Symposium on 1700th Anniversary of Christian Armenia The faith of the ancient councils - I Nicaea, I Constantinople, Ephesus, Chalcedon, II Constantinople, III Constantinople, II Nicaea - is consistent, whether one labels all seven or only the first three as ecumenical. But their terminology is not always consistent. I Nicaea, for example, used the words hypostasis and ousia as synonyms, while the later councils took great pains to distinguish them. So too, the anathemas of the ancient councils are not always consistent. Too often we have mistaken the “short-hand” of later periods for historical fact. The conclusion of the Joint Commission therefore is quite appropriate: “Both families agree that the lifting of anathemas and condemnations will be consummated on the basis that the Councils and fathers previously anathematized or condemned are not heretical” (1990 Chambesy Agreed Statement, para. 10). But will this happen any time in the foreseeable future?
