One of the great debates concerning religious truth questions was aired on the BBC in 1948. It pitted two intellectual giants: Bertrand Russell, one of the fathers of modern analytic philosophy, and Frederick Copleston, a Catholic priest who edited the best history of philosophy ever written. If memory serves, it was printed in John Hick's The Existence of God, which is where I originally read it.
One of the great statements of both the cosmological argument for the existence of God and of the moral argument can be found here--magnificently defended against one of the 20th century's great atheist philosophers. It always seemed to me that Copleston clearly bested Russell here. But you'll have to make your own assessment.
In any case, it's nice to see it on the web.
