I am a Deist, and there are no Deist churches.
Hmmm... this brings a new poll question to mind.
I don't go to church to worship God, I get plenty of that on my own personal time. I go to church to hear the insight and teachings of other men and women I respect, and to hear their interpretation of the Divine Scriptures. I happen to be fortunate enough to attend a church where that description (Divine Scriptures) ranges from the Bible, to the Dhammapada, to the Bhagavad Gita, to the Tao Te Ching, to Rumi, and beyond.
I actually LOVE going to church, and never miss it these days.
In Germany, many masons don't belong to a church, and in my eyes that is a problem, because in our largest GL, religious neutrality changed into anti-clericalizm and a refusal of any organized faith.
My GL has a gite high percentage of church members, as we are a christian order, even in blue lodge.
