Douglas Wilson interacted with Christopher Hitches on a number of occasion leading ultimately to this documentary. Over at this blog in 2009 he spent some time adding to his interactions. Here is an example:
Christopher said somewhere that extraordinary claims require extraordinary proof. This is quite true, but Christopher misses the point of it. He thinks the resurrection is the extraordinary claim, when actually it is the extraordinary proof. You should not listen to a man who claims to be God (the extraordinary claim) unless He does something like come back from the dead. The resurrection is God’s declaration that Jesus is the Son of God (Rom. 1:4), and when we preach the resurrection, as we are charged to do, we are preaching the proof, not something that needs to be proven. God adds to the proof by anointing all such faithful preaching with His power, testifying to the testimony. It is the power of the Spirit that will convert the world by this means.
