How would you represent "religion" in an icon, neutrally?
I am involved in a web application where items in a list have a category. Each category of an item is shown through the use of an expressive icon. One of the categories is religion.
My coworker, a graphic designer, is at a loss on how he would represent religion in a logo "neutrally". Some of the items may be associated with Christianity, Islam, Buddhism, etc. so a religion-specific icon would not work and may be potentially offensive.
So, is there a way we can represent it in a different way?
What about an icon depicting a set of praying hands?
Edit: It seems that Civilization 4 uses something similar: Check out the seventh icon in the row of icons in the top-right corner of this screenshot, below "PM".
Most airports I've seen that have a multi-faith room use, if not just text, some human figure in what you could call a prayer position:
