"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'."
