Whether Orthodox Church belong or not is not issue, Council of Churchs is think tank, it not set Orthodox Dogma or Policy. Try doing bit of research before maliegning 300 million Christians with ignorance.
The National Council of Churches is more than a think tank. Research the history of the National Council of Churches. I'll include only one link that sheds a little light on this evil group.
Do a google on National Council of Churches and homosexuality and see what you get.
I'm happy if your church so far has resisted the acceptance and promotion of homosexuality but it doesn't change the basic fact that the NCC is very, very liberal.
