So, the number of Christians of the major traditional denominations has dropped below a million of people. However, people in the Czech Republic are not entirely atheist. I am for instance not a practicing Christian but I believe in God. Not necessarily the God of the bible, but the notion that there is something bigger than the purely temporal.
The land is swarming with cults, like the one of Guru Jára, which I recently mentioned. Religion has been replaced by spirituality and your garden variety witchy stuff. I really wonder whether anyone researches new religious movements in the Czech Republic, somebody does, or maybe I should.
