The Creative Process: Something Else About Faith

I'm not a religious person.

I know, I know. You all must be shocked by that news. I'm sure that most good, wholesome, God-fearing people spend their Labor Day talking about tentacle porn, vending machines with used underwear, and assorted other "goodies."

But yes, it's true. I'm not a religious person.

So, the problem becomes a thorny one when I decide that one of the potential scripts bouncing around my head has some perhaps very strong religious overtones.

The question - how does a non-religious person suddenly acquaint themselves enough with the Bible to make their story believable?

Or the subquestion - much like in Almost Famous when the kid asks "Do you have to be sad to write a sad song? Do you have to be in love to write a love song?"... my question becomes "Do you have to be religious to write about religion?"

Thoughts?
