Luther and Lewis

What we are discussing here is another kingdom, one which in no way weakens or annuls the other, namely, spiritual life and existence among Christians, where it is forbidden to judge and condemn another. The devil always mixes into such judging to do his work. He gives each individual a high estimate of himself.—Martin Luther AE 21:211

What are the key words of modern criticism? Creative, with its opposite derivative; spontaneity, with its opposite convention; freedom, contrasted with rules.—C. S. Lewis, Business of Heaven, p. 216
