The Germans

Along with Nietzsche ( whom I regard as the first deconstructor of liberalism - including liberal Christianity), these are the must read Germans...
I propose this as an alternate list to the "harmful" Germans.

Bonhoeffer was the best man of them all, with Leddihn and Rosenstock-Huessy closely following.
I include Barth for, at the least, his incredible influence on both Protestants and Catholics. Personally, Van Til's reading of him is a bit unfair, at best. Van Til's concern to defend a pre-apologetic "Christian Theism" lead him to insist upon a God-centered theology (his rhetorical choice of words) as opposed to man-centered Barthianism with its "God" which was "Wholly Other". A more sympathetic reading of Barth (and a Van Tillian reading of Van Til) might point out that Barth was concerned to defend the unknowability of God's essence (as opposed to His energies and His revelation and His Incarnation) as well as asking Van Til if "man" and "God" dichotomies were the best place to begin theology in a post-Incarnation world. This is not an endorsement in toto of Barth, or a blanket recommendation, just a suggestion that Barth deserves more recognition than he was received so far.

And of course, I would be remiss not to recommend this man:http://en.wikipedia.org/wiki/Goethe.
Read Faust. It ain't Job, but it's updated and humanized for people who can't make the imaginative effort to fathom the tragi-comedy of Job.
