"The human virtues are, I insist, the foundation for the supernatural ones. These in turn provide us with constant encouragement to behave as good human beings. In either case, it is not sufficient merely to want to have these virtues. We have to learn how to practise them. Discite benefacere, learn to do good. We need to make a habit of exercising each virtue, by actually being sincere, truthful, balanced, calm and patient... for love is proved by deeds and we cannot love God only by word, but 'with deeds and in truth'."
