Orthodoxy as a state religion and the opinions expressed in this thread are two different things. Orthodoxy as a state religion does not (necessarily) imply enshrining the catechism into the law, as our enthusiastic convert would like.
Did I ever say that? I don't think I ever did...
In my honest opinion, we definitely do need to convert the whole world to Orthodoxy. This definitely doesn't mean that you convert by force.
It seems today that we aren't actively trying to evangelize in non-Orthodox nations. (of course, a few exceptions like Central America) It seems Orthodox Churches refuse to touch Western European nations, or even Islamic Nations. (or even Hindu/Buddhist ones)
From what I've seen, it seems that our Orthodox Churches even have "deals" with other Christian groups like the Roman Catholics where we agree not to actively proselytize in their countries. I say to heck with those deals (if they actually exist), they aren't bringing anyone to Orthodoxy.
Orthodoxy isn't about sitting on your bum thinking about just yourself and God. As St. Seraphim of Sarov says, "Acquire the Holy Spirit, and thousands around you will be saved."
When Noah was building the Ark, did he just sit around and refuse to warn others? Did he focus on only saving himself? No he didn't.
The Church is the Ark of Salvation, if people won't listen to her message, then that's their problem. But it is our job (with the help of the Lord) to bring as many people to the Ark as possible.
No one can deny that the world is not getting better, it's getting worse. The waters are rising fast, and many of us are drowning. If we are on the Ark, we need to help pull them aboard, not just sit around and stare at them while they drown, that is just sadistic.
As for the Church & State thing. As I said, I don't think it should occur in non-Orthodox majority states. But even so, it should be our job to make those countries Orthodox (or more Orthodox).
This anti-Church/State idea comes from the West, and more specifically from the United States, which is NOT a Christian nation, and many of it's ideals were more founded in deism than Christianity.
Should a nation founded by Freemasons and Deists be a model for Orthodox Christians? Or should we follow the model of nations/empires founded and run by Orthodox?
Regarding the whole issue of the government "enforcing" certain "laws"... You must recognize that in the Byzantine Empire, it was often the Emperor who called the Councils. If someone violated the canons or doctrines of the Church, the Church can excommunicate them, but it was the Empire that handed out further "punishment" which often included exile, which the Church couldn't do.
You also cannot use the argument that "a few bad apples makes the whole orchard rotten". Just because there were some Emperors that were evil doesn't make the whole idea of an Orthodox State wrong. That is just stupid. Using that argument, you could further argue that the Orthodox Church shouldn't have hierarchy because there are often evil and heterodox Bishops (and even Priests). It makes no sense to argue with that.
It is admirable that in Russia today, Orthodoxy HAS to be taught in the schools. They also encourage the teaching of Islam and Judaism. They can also teach about Roman Catholicism and others. But they are required to teach Orthodoxy to the students.
I think it is also good that the Patriarch of Moscow is an advisor to the President & Vice President. It is also good that both are seen regularly at Church services, and regularly with the Patriarch. Are they honest in their faith? We don't have any right to judge that. But it shows that Russia truly is Orthodox, and that Orthodoxy is truly the right faith, and others are not even close to equal with it.
In the Byzantine Empire, the Church & the State were close, but the Patriarch didn't (or wasn't supposed to) meddle in political affairs, and the Emperor wasn't supposed to meddle in Church affairs.
Are we declaring a jihad? No... Are we declaring war? No... Why is that? Because war has already been declared on us. The world wants to destroy us, and the world is commanded by it's master. To quote the famous Orthodox publication, we seek "Death to the World". We wish to slay the passions. The powers of evil are warring against us, and wish to annihilate us. They use violence, deceit, hatred, and many other methods (including secularism) against us to lead us away from God.
Of course, I think all of us know this, and I'm probably just preaching to the choir, but I'm trying to make a point here.
