None at all. Being a religious Christian in Europe is mostly about accepting the general values of Judeo-Christian tradition and not being overtly atheist. Almost no one goes to church or observes any religious traditions at all, yet most people claim to be Christians. As long as someone doesn't badmouth Jesus nor claims that religion is "opium for the masses", they pass for Christian in EU.
