Found even more evidence of Waldron being a Christian. His book "Torture, Terror, and Trade-Offs" has a chapter in it entitled "What Can Christian Teaching Add to the Debate about Torture?" In that chapter are several comments indicating the author's Christianity. I'll share the following quote from it:

"The last point I will raise is one we need to approach with the greatest caution, but which can never be far from the mind of a Christian contemplating the issue of torture. Our Savior Christ, we know, was not just put to death; as we say in the creed, He suffered under Pontius Pilate."
