I don't know if I'm off-base, but I see this as an extension of the "Europinization" of Greece that has been a slow process since 1821. The heavy influence of Western Europe on the very different Greek people has changed the culture; at first slowly, with the seeds of European nationalism and such, but over time the influence of western social and political philosophy has changed the landscape of Greece tremendously.
Well, you're right in a way.
But not exactly.
The "europinization" of the country started a long time ago, with Kostas Simitis of the SocialDemocrat party, who also had a similar issue with the Archdiocese over the new CVs, that would not include the religious denomination of the person on them.
Well, that ended in a triumph of the Socialdemocrats. He had the chance to raise the issue then, as well.
Right now, the issue is being raised because the Metropolitans talk too much.
Just a few days ago, the former prime Minister, Kostas Simitis (the above), wrote a book about himself, that caused a lot of controversy, and along with it, the response of a metropolitan (the metropolitan of Mesogaia & Kalavrita) and the Archdiocese backing him up.
Ever since, the socialists are practically screaming for a Church-State separation, and the issue is evolving.
Yesterday, I was watching on TV a discussion in which people from various political parties, and representatives of the Church (a priest, a theologian & the metropolitan of Thessaloniki) took part. The idea I got was that those demanding Church-State separation were mostly demanding it, in order to silence the metropolitans, and this is also what the metropolitan pointed out, that this "demand" is targeted at the archdiocese
, although he intentionally
didn't mention by whom.
