Should I have a doscussion with my parent's Church pastor?

If you are looking for an intellectual debate, I would say the chances of that are extremely low. You're most likely to get deflections and bumhole rationalizations. I'd bet money you know way more than him.

But who knows, maybe he's a really liberal Christian who has actually learned a bit objectively about his religion and his book. Most of them don't know the history of their book, in fact they are grossly misinformed. I guess it could be worth a try, as long as you don't have too high expectations.
