FAITH THE PARTNER OF CHARITY
Neither charity alone nor faith alone can produce good works, any more than a husband alone or a wife alone can have offspring. The truths of faith not only illuminate charity, but qualify it, too; and, moreover, they nourish it. A man, then, who has charity and not truths of faith, is like one walking in a garden in the night-time, snatching fruit from the trees without knowing whether it is of a good or evil use.
