In January 1920, the Ecumenical Patriarchate issued an encyclical – “Unto all the Churches of Christ Wheresoever They Be” – which has played a key role in the history of the ecumenical movement and the engagement of the Orthodox Church in it. The document was prepared by a group of theologians of the Ecumenical Patriarchate headed by Metropolitan Germanos (Strenopoulos). At the time of its publication, it had an official English version; however, it is usually referenced according to its later revised translation, undertaken in 1959 by W. A. Visser ’t Hooft. A significant difference is that the 1920 translation did not include what has come to be seen as the central feature of the 1920 encyclical: that is, the proposal to create a “League of Churches.” The article explores whether the revision is a more accurate translation of the Greek original or rather an interpretation of the encyclical that enshrines in the text its key concept – which was, however, not contained in the original document.
