Ironically the church in Europe, especially northern Europe, seems to be nothing like as strong as it is in America. One reason for that could be that as the church here became part of the political establishment it became more exposed to open debate and to being tainted by political wrongs, and that killed a lot of its support. It may well be therefore that the separation is the thing which has kept the churches alive in America. Those theists who want to end the separation should perhaps remember the old saying. Be careful of what you wish for; you may just get it.
