The chief assertion of religious morality is that white is a colour. Virtue is not the absence of vices or the avoidance of moral dangers; virtue is a vivid and separate thing, like pain or a particular smell.
Mercy does not mean not being cruel or sparing people revenge or punishment; it means a plain and positive thing like the sun, which one has either seen or not seen. Chastity does not mean abstention from sexual wrong; it means something flaming, like Joan of Arc. In a word, God paints in many colours; but He never paints so gorgeously, I had almost said so gaudily, as when He paints in white.
