> I can't think of any reason for why the church would invent a new dialect? <
I grew up and served in the Coptic Church. I attended thousands of liturgies, sermons, and studies. And I “knew” that prayers and hymns were in 2 languages: Arabic and Coptic. Then I moved to an area with no Coptic church and attended a Greek church for several months. I was overjoyed to find that they prayed similar prayers.
But my joy was mixed with anger because nobody in the Coptic Church ever told me that they actually used 3 languages: Arabic, Bohairic, and Greek. Nothing is wrong with using Greek in the liturgy. Indeed, it is beautiful. But to claim that Greek prayers and hymns are in Coptic language borders on plagiarism.
Since a significant proportion of Coptic liturgy is in Greek, and since the correct pronounciation of these prayers had been lost during the Arab rule, it made sense for the Coptic Church in the 19th century to learn from the Greeks how they pronounced their prayers and hymns. This seems like a worthy cause.
However, in the process, and this is my own understanding, the Bohairic portions of the liturgy also got Grecized, resulting in a backlash from adherents of the “old” pronunciation. I hope that the dispute involves only Bohairic prayers and not Greek prayers, as well. It would be a silly attempt and further plagiarism to use the “old” pronounciation for the Greek prayers.
> Sahidic was the most wide spread dialect starting from cairo to the edges of upper Egypt so if you want to write a book that most Egyptians will understand at that time, you should either write it in Sahidic or Greek <
Quite true. The New Testament was translated first to Sahidic. And, my understanding is that the Bohairic version uses Greek too often. Sahidic is the ancient Egyptian language. It is Sahidic that is taught in universities all over the world because there are many important documents written in it.
> speaking Sahidic is not very easy though, do we have any phonetic transcription of any Sahidic text? even in that case Sahidic is easy for people who speak the Sahidic dialect of Arabic <
I don’t speak Sahidic Arabic, and neither do all the scholars worldwide who study Sahidic Coptic. It may be impossible to know how exactly it was pronounced. But, in my humble opinion, we should do our best. The main step would be for Copts to realize the importance of Sahidic Coptic.
God bless you.
