" If they love their children parents must, sparingly and carefully perhaps but nonetheless actively, confront and criticize them from time to time, just as they must allow their children to confront and criticize themselves in turn. Similarly, loving spouses must repeatedly confront each other if the marriage relationship is to serve the function of promoting the spiritual growth of the partners. "
