Luther and Lewis

And thus the Christian Church has held her own from the beginning until now amid innumerable false spirits which have been from the beginning and may still come. And yet she goes on standing firmly by her Baptism, Lord’s Supper, Gospel, Christ, the Ten Commandments, and true and pure prayer, and thus she judges and separates herself from all false teaching which is opposed to her—yes, even though the devil should become an angel of light and as a beautiful and radiant figure should present himself as God.—Martin Luther, on Jn xiv, xv

[Screwtape to Wormwood] If any faint suspicion of your existence begins to arise in his mind, suggest to him a picture of something in red tights, and persuade him that since he cannot believe in that (it is an old textbook method of confusing them) he therefore cannot believe in you.—C. S. Lewis, Business of Heaven, p. 260.
