Happy is the man who has found wisdom. Even more happy is the man who lives in wisdom, for he perceives its abundance. There are three ways for wisdom or prudence to abound in you: if you confess your sins, if you give thanks and praise, and if your speech is edifying. Man believes with his heart and so he is justified. He confesses with his lips and so he is saved. In the beginning of his speech the just man is his own accuser, next he gives glory to God, and thirdly, if his wisdom extends that far, he edifies his neighbour.
Saint Bernard, abbot
