Abstract: | Since its beginnings, the ecumenical movement has been influenced by the Orthodox Church, as seen, for example, in the 1920 Encyclical of the Ecumenical Patriarchate. Two convictions have underpinned the ecumenical commitment of the Orthodox Church: the need for better mutual understanding between churches and the desire of the Orthodox Church to witness to the truth in its ecumenical relations. There have been instances where the Orthodox Church has not been able to assert its views, and indeed its dialogue partners have come to decisions contrary to the principles of the Orthodox Church. However, this article will focus on the extent to which the Orthodox Church has been able to present its message and effectively influence developments, something that can be observed mainly in two areas: (i) the early church creedal tradition, specifically the Nicene Creed, and (ii) the liturgical heritage, particularly the relationship between baptism and chrismation. |
