The Brits have always had a unique perspective on this. When visiting Westminster Abbey for the first time back in the '70s, I was amazed to find a particular within in the floor in a prominant position in England's National Church. It was Charles Darwin.
And some creationist type will come along and claim that the Church of England is Apostate or isn't really Christian, hence the explanation for finding a positive Chruch-Darwin connection.
I've been there, and I've seen it. I think (but don't really know) that Darwin always regarded himself as Christian. He studied for the ministry, and was certainly devout as a young man. He did seem to have some doubts late in life.
Those who are always popping into these threads to babble that eeee-villl-uuuuu-shun is the direct road to atheism, sodomy, mass murder, communism, etc. can never quite deal with the exemplary life of Darwin. Or the thousands of biology teachers, scientists, etc. who don't exhibit the "inevitable" consequences that the anti-evos imagine will follow from learning science.
Not that such things are evidence for or against Darwin's work. A scientific theory stands or falls on the evidence for or against the theory. Darwin's biography is irrelevant. But he seems to have been a worthy gentleman of his generation.
