On February 6/19, Bishop Ambrose of Philippi was received into the Church of the GOC of Greece under the Presidency of Archbishop Kallinikos, from the GOC under Archbishop Makarios.
A source familiar with the situation indicated that Bishop Ambrose had become discontent with the recent union between the GOC-M and the Holy Orthodox Church in North America (HOCNA). Recently, Metropolitan Christophoros of Mesagaias walled himself off from the GOC-M for the same reason and remains independent.
Further details will be posted as they become available.
