There are a number of Orthodox churches. The five largest ones are based in Constantinople, Alexandria, Antioch, Jerusalem and Moscow, in order of their precedence. Pope Francis had previously met with the first four. Patriarch Bartholomew of Constantinople (or Istanbul), the so-called first among equals of Eastern Orthodox Catholic Church in 2013. But the Russian patriarch has issues with the Catholic Church that the others do not have. Not surprisingly, these issues have both political AND ecclesiastical roots. And now, Pope Francis has just met with the last and final patriarch. This brings the whole orthodox communion, the second largest church in the world into fraternal and ecumenical dialogue with Rome. Do you think that soon the wound between them will be healed?
