I was reading selections last night from a volume of C.S. Lewis’ letters and came across an interesting (and rather amusing) one to his brother on February 18, 1940. Apparently Lewis had recently encountered a group of zealous students of this newfangled theologian Karl Barth:

Did you fondly believe – I did – that where you got among Christians, there, at least, you would escape (as behind a wall from a keen wind) from the horrible ferocity and grimness of modern thought? Not a bit of it. I blundered into it all, imagining that I was the upholder of the old, stern doctrines against modern quasi-Christian slush: only to find that my “sterness” was their “slush.” They’ve all been reading a dreadful man called Karl Barth, who seems the right opposite number to Karl Marx. “Under judgment” is their great expression. They all talk like Covenanters or old Testament prophets. They don’t think human reason or human conscience of any value at all: they maintain, as stoutly as Calvin, that there’s no reason why God’s dealings should appear just (let alone, merciful) to us: and they maintain the doctrine that all our righteousness is filthy rags with a fierceness and sincerity which is like a blow in the face…

I don’t know if Lewis ever changed his opinion about Barth in light of the latter’s developed thought, but it’s interesting to see Lewis, the old-fashioned Christian humanist and upholder of reason in matters of faith and morals, clashing with the upstart “neo-orthodox” theology. Certainly “Barthians” of various stripes seem to dominate much of the field of academic theology nowadays, which makes you wonder where Lewis would fit in if he were still around. His critical approach to the Bible would not find favor with a lot of conservative evangelicals, but the high value he placed on human reason wouldn’t sit well with various neo-Barthian, “radically orthodox,” and post-liberal theologies.
