The Anglican and Eastern Churches Association is a religious organization founded as the Eastern Church Association in 1864 by John Mason Neale and others and of which Athelstan Riley was a leading member. The purpose for which it was founded is to pray and work for the reunion of the Eastern Orthodox Churches and the Anglican Communion. In 1914 it adopted the present name when it merged with the Anglican and Eastern Orthodox Churches Union. According to tradition the merger was arranged at a meeting under a railway bridge in Lewisham between the Rev. H. J. Fynes-Clinton and the Rev. Canon J. A. Douglas. In 1933 there was a dispute between Fynes-Clinton and Fr Robert Corbould on one side and Athelstan Riley and Douglas on the other.
It publishes Koinonia: the journal of the Anglican and Eastern Churches Association; this continues E.C.N.L.
