That's not actually true. There are plenty of atheist priests as it's a job just like any other. More to the point if you survey the worlds religions you don't actually find much consensus of any kind. Just ask a shinto priest how the world was created and compare that with the native Australia dream time. http://en.wikipedia.org/wiki/Dreamtime Even more enlightening 'God' as a concept aka a supreme higher power does not even translate into every language.

PS: Restrict it to christian priests and you still don't really find consensus. "More than 80 per cent were happy with the idea that God the Father created the world." http://www.telegraph.co.uk/news/uknews/1403106/One-third-of-...
