The Foolishness of God is an in-depth look at Martin Luther’s stance on the role of reason within Christianity. What does the Bible teach about human reason? Does reason have the ability to judge the Bible? Is Christianity intellectually defendable? The author works to clear up confusion over Luther’s concept of reason. It would be difficult to find a better description of Luther’s view of reason than the one provided by the author: “It is not Christianity that needs to be made reasonable. It is reason that needs to be made Christian.”
