Middle East Council of Churches
The Middle East Council of Churches (MECC) was inaugurated in May 1974 at its First General Assembly in Nicosia, Cyprus, and now has its headquarters in Beirut, Lebanon. Initially it consisted of three "families" of Christian Churches in the Middle East, the Eastern Orthodox Churches, the Oriental Orthodox Churches and the Evangelical Churches, which were joined in 1990 by the Catholic Churches of the region.
