An old friend of mine from Rochester, a pastor with a PhD in Physics named George, creates a mock dialogue between the believer and the skeptic. A great summary of the different defense postures of the Christian when discussing religion with skeptics. Of interest to me (because I never thought of them before) was his criticism of the typical skeptic refusal of a null hypothesis and doing a test that falsifies their hypothesis of God’s non-existence. That is a way to turn the burden of proof to the skeptic.
I also liked the straw-man criticism of the typical “how could a ‘good’ God do bad thing xyz…†skeptical criticism of Christianity. How often have I heard the argument that God is “evil” from a worldview where there is no God. I have always believed that good criticism must borrow the worldview of the the other in order to be effective.
