Luther and Lewis

He wants my whole heart; for the outward things, as the outward virtues, are only maid servants; he wants the wife herself. He demands, that I say from the bottom of my heart: I am thine. The union and the marriage are accomplished by faith, so that I rely fully and freely upon him, that he is mine. If I only have him, what can I desire more?—Martin Luther, Homily for Trinity 20 (CP V:232)

There are three things that spread the Christ-life to us: baptism, belief, and that mysterious action which different Christians call by different names—Holy Communion, the Mass, the Lord’s Supper. At least, those are the three ordinary methods.—C. S. Lewis, Business of Heaven, p. 267.
