Christ came to enlighten those who lived in darkness, overshadowed by death, and to guide their feet into the way of peace. Do you ask what darkness? Whatever is present in our intellect, in our will, or in our memory that is not God, or which has not its source in God; that is to say, whatever in us is not for God’s sake, is a barrier between God and the soul— it is darkness.
–John Justus Landsburg (1489-1539)
