Most russians (and other ethnicities living here) are atheists. I know a lot of guys who consider that they are belong to Orthodox Church but all of them visited to the church only one or to times in their life and they all dont know any prayers and all of them never keep the fast. There are a lot of tatars and bashkirs here in the Urals, they mostly class themself with Muslims but everything I wrote befor about Orthodox Church is right for them too. I know the only two church fetes that selebrates here - Easter and Kurban-Bairam.
