Dear Sister in Christ Aydan:
There have been many responses to this thread, but I would like to take a few moments to clarify some things about Coptic Christianity.
First of all the term Copt, strictly used, refers to the indigenous inhabitants of Egypt, regardless of religion. It is commonly used to refer to Egyptian Christians.
Most (around 15 million worldwide) Egyptian Christians belong to the Coptic Orthodox Church. Somewhat fewer (300,000 or so) belong to the Greek Orthodox Patriarchate. Even fewer (less that 250,000 worldwide) belong to the Coptic Catholic Church. Of these only around 50,000 live outside of Egypt.
The official liturgical language of the Coptic Orthodox Church is Coptic. Coptic is the last form of the ancient Egyptian language which was spoken during Egypt’s Christian period. The language was suppressed in public life by the Moslem conquerors of Egypt, and is rarely spoken outside of Church anymore. Coptic uses an alphabet similar to the Greek, and is read from right to left, like Greek. It is not related to Arabic (or Turkish) at all.The Liturgy, and most Church publications also use Arabic extensively, and in countries of immigration the local language will be used as well.
There are no Coptic Churches (Catholic or Orthodox) operating in Turkey, nor are there any Coptic monasteries. The Syriac Orthodox Church Church has several very ancient Monasteries in Turkey. The Monks there wear headcoverings which look like black hoods with 12 white crosses on them, just like the Coptic Monks, so perhaps this is where the confusion arose. There are Coptic Monasteries outside of Egypt, in Europe, the US and I believe Australia as well as the Holy Land, but not Turkey. The Syriac monks use Syriac in their services, and Turkish as well because it is the local language. The Syriac Church was nearly exterminated in Turkey over the course of the 20th century, and today most Syriac Christians live elsewhere.
It should also be noted in the interest of historical accuracy, that the Turkish people (as opposed to people who happen to live in Turkey), migrated to Anatolia from Central Asia in the 11th Century and were already Moslem when they arrived. Most of the Saints from the area which is now Turkey were of other ethnic groups (Greek, Cappadocian, Assyrian, etc).
Hope this helps
