Why do I have to disclose religious faith to get health insurance?

I like many people have to look for new health insurance from time to time (thanks, republicans).  I recently was contacted by a “cost sharing” company called alitieri (sp?) and on the way to signing up I was required to answer questions about whether I believed in GOD, would I keep my health as GOD intended and some other religion related question.  What does this have to do with paying for health care?  Anyone had this company?
