ABSTRACT
Entering the new millennium, Greek Orthodox Churches and communities have gone through major difficulties and transformations in world politics. In less than a century the international and regional environment where these Churches used to operate has radically changed. The experience of multi-ethnic empires, Byzantine or Ottoman, was replaced by the advent of nationalism, nation-states and sometimes ethnic-sectarian strife. The regional character of the Churches has also been changing with the increase of the role of the diasporic Church.
