I play golf with a one time Minister in a Protestant Church who after many years took off the collar and went forth into the business world. He became very successful. He also kept his faith. We often discuss religion, me as an atheist and him as a believer. Yesterday we were trying to figure out why more and more people are describing themselves as 'none' when asked about their beliefs. I feel the internet and its ability to open peoples eyes to so many points of view is responsible. He believes that the great scientific discoveries of the last few decades, especially in physics and cosmology are responsible. I think we are both correct to a certain extent.
No matter what we think the latest Pew Surveys show that people believe less and less in the dogma of the different religions. That doesn't mean they aren't spiritual, just that they don't believe in the stories and fables surrounding religion. I think this trend will continue but there will always be believers.
