Christ is among us!
Hehehe...first of all Turkey keeps on making promises, and that is their MO: promises, but no action, so unfortunately, I would not hold my breath for the opening of Halki Seminary any time soon. They have promised this before....Hopefully I am wrong.
Secondly, I lived in Greece for a while and I do not think that Greeks treat Muslims badly and beat them up! Infact, Greeks treat Muslims pretty well considering... Ofcourse, we need to remember that Greece suffered 400 years under the Ottoman Muslim overlord. The wounds of bishops being publically skewered and burned like animals, and such acts are still not completely healed. We need to remember that Islam does nothing to accomodate Christians. Ask any Middle Eastern Christian living there today. The philosophy of Islam is to bring all 'infidels' under their control.
As far as Constantinople/Istanbul, do not worry, the prophecies of holy monastics tell us that it will once again be Orthodox. Infact, according to the holy Elder Paissios (+1996) you will probably be alive to see a great war in that part of the world. Russia will bring Orthodoxy back to the Mother City, and because of the great war, Turkey will need to remove its soldiers and tanks from Cyprus to fight on the mainland...therefore, Cyprus will see the Turks finally leave!
