Well I am definitely not one of those Christians who think that everybody must be the same brand of Christianity as me..
Orthodox religion (Russian and Greek) are supposed to be the closest to the Original Chrisitianity from the first century. That makes it pretty interesting! Plus the churches of the orthodox religion are very impressive. (Compare with a Lutheran church, just a plain stone building with white walls inside -- not saints, icons or illustrations on the wall, usually.)
In Sweden the Church is run by the state, and all the bishops are appointed by the state. The state has been social democratic for almost 100 years, so the same is true for the Church. The result of this is that the sermons are ALWAYS about things like solidarity and justice, instead of biblical messages. Plus, it is always prioritising "politically correct" values over biblical values.. I.e. homosexuals can have their "union" blessed in church and plenty more very unbiblical practices. In my opinion they are seriously undermining their own credibility. How can anybody take them seriously when they always change their dogma and do things which are contradictory to the bible? I go to the Swedish church in London sometimes, but only for social reasons, not for religious reasons -- it's like a community meeting place more than a church.
