Russia is ripe for a religious revolution of some variety. God help us if the Muslims take over their culture. It will be a mess. Cagey Thanks for those words. The Christian tradition native to Russia needs to reinvent itself and become a viable vehicle for the rehabilitation of Russia.
Every religion adapts in some ways to current times and situations.
There is no reason, though, for any religion to change the tenets of its faith or its mode of worship to suit current fashions. If the Russian Orthodox Church changes now, when Orthodoxy hasn't changed in 2000 years, that would hardly be a propitious sign. I am unaware of anti-modernism being any kind of tenet of Orthodox Christianity, although there is certainly a strongly skeptical attitude within the Orthodox Church toward the modern world and the diseases of the soul it carries. The same is true of devout Catholics and Protestants, I dare say. I am no fan of Catholicism, but I would say that the Roman Church of the era of Leo XIII and Pius X was a far healthier place than the Roman Church of today.
