CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1770–1773

1770 Moral perfection consists in man's being moved to the good not by his will alone, but also by his sensitive appetite, as in the words of the psalm: "My heart and flesh sing for joy to the living God."
1771 The term "passions" refers to the affections or the feelings. By his emotions man intuits the good and suspects evil.
1772 The principal passions are love and hatred, desire and fear, joy, sadness, and anger.
1773 In the passions, as movements of the sensitive appetite, there is neither moral good nor evil. But insofar as they engage reason and will, there is moral good or evil in them.
