Dr. David Madison is part of a growing wave of openly atheist biblical scholars, and a signatory of The Manifesto for Secular Scriptural Scholarship and Religious Studies.
As a former believer, he knows how believers think. As an academically trained biblical scholar (PhD in Biblical Studies from Boston University), he knows how to detect the defects of apologetic arguments.
Dr. Madison now has published Ten Tough Problems in Christian Thought and Belief: A Minister-Turned-Atheist Shows Why you Should Ditch the Faith that provides a good survey of the basic problems with Christian belief. I highly recommend it.
Here is the published description.
“An all-powerful God who permits unspeakable horrors and sent a Son who threatened more to come, forever, to those who don’t believe in him. An inspired holy book that turns out to be full of archaic nonsense, moral failures, and contradictions. A world of disagreement not just between Christians and other religions, but within Christianity itself. Blood sacrifice and a tale of the walking dead as the very foundation of faith. These are just a few aspects of Ten very Tough Problems that David Madison describes in this wonderfully deep yet humorous dismantling of his former faith. Combining rigorous scholarship with engaging personal reflections and refreshing wit, he offers understanding and even some laughs while walking with readers past the gravestones of Christian thought and belief.”
