It's a great achievement for the country where atheism was the official state religion for more than 70 years. They appreciate Christian moral values but do not follow them. Russians are more aware of horoscopes than the Bible.Church service in Russia can be attended any day of the week and performed every day 2 or 3 times (early morning at 3 a.m., then at 8 a.m. People usually attend the church just to "light a candle" and quickly pray.Russian saying is, "One is not a soldier in the battlefield".In Russia, one still needs to know people in power to make things work.This is why they maintain more friendships than an average westerner.They often have to rely on their friends to help them out.
Also attending performances in a company is always much more fun, which contributed to the popularity of theatres.
They do it to ask for something to happen (a business deal, an exam) or to remember a close person who is dead.
People do not have to be a member of the church to do it and they do not have monthly contributions to the church.
Intellectually, Russians are interesting people to talk to and enjoy deep subjects.
Philosophy is still a mandatory subject when you study for a degree and one of the 3 compulsory subjects for Ph D qualifying exam (the other 2 are foreign language and the specialty itself).
