I was born in Greece and I attended primary and two years of high school before my family moved to Australia at the age of 12. I was an average student at best!
Upon arrival to Australia, I completely ignored Greek and focussed on English. I only practised Greek when we spoke at home. In my mid-thirties I turned back to the Church. I would say my level of Greek is still no better than that of a 12 year old.
Since turning back, I've never felt that my lack of understanding of the language of the DL is a problem. Have I wished that I could understand more/all? Sure, but to turn to my priest and say that I can't come because I don’t understand, is such a distortion of the truth that its almost an outright lie.
What a lot of the forum members would not know is that Greeks in Greece get exposed to many of the 'flavours' of the Greek languages through the school, media, family and traditions. It is not as if these old forms of Greek are alien to us. If _I_ can read the Gospels with little trouble, ignorant as I am, how much more the Greek natives who have completed Greek middle school + high school (grades 7-12)?
I find it strange that in this day and age when the general population of Greece is educated, school is compulsory and funded by government (books and all), that there are people who use this as an excuse. Even more strange that Church bishops accept this excuse.
What should our grandfathers and mothers say then, when most of them were almost illiterate? My younger brother, even less educated than me, has never once said that language is a problem. His wife, a Romanian Orthodox with a surprising good command of modern Greek, attends Church and she's never complained. Work, sure. But the language, this is reaching I think.
I am not saying that the Church should turn these people away or ignore their 'concern' but to make such large scale changes to the DL, for a minority (numbers anyone?), is not necessary and would be very damaging I think. I particularly liked the idea of another poster who mentioned of the Latin mass in a side by side format. That I believe is the way the Church should move.
As for Greeks outside Greece, there is little to none of the exposure that I mentioned above. In fact, the sooner the Greek Churches outside Greece start using English or whatever the native language is, the better.
