CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1802–1806

1802 The Word of God is a light for our path. We must assimilate it in faith and prayer and put it into practice. This is how moral conscience is formed.
1803 "Whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is gracious, if there is any excellence, if there is anything worthy of praise, think about these things."

A virtue is an habitual and firm disposition to do the good. It allows the person not only to perform good acts, but to give the best of himself. The virtuous person tends toward the good with all his sensory and spiritual powers; he pursues the good and chooses it in concrete actions.

The goal of a virtuous life is to become like God.

1804 Human virtues are firm attitudes, stable dispositions, habitual perfections of intellect and will that govern our actions, order our passions, and guide our conduct according to reason and faith. They make possible ease, self-mastery, and joy in leading a morally good life. The virtuous man is he who freely practices the good.

The moral virtues are acquired by human effort. They are the fruit and seed of morally good acts; they dispose all the powers of the human being for communion with divine love.

1805 Four virtues play a pivotal role and accordingly are called "cardinal"; all the others are grouped around them. They are: prudence, justice, fortitude, and temperance. "If anyone loves righteousness, [Wisdom's] labors are virtues; for she teaches temperance and prudence, justice, and courage." These virtues are praised under other names in many passages of Scripture.
1806 Prudence is the virtue that disposes practical reason to discern our true good in every circumstance and to choose the right means of achieving it; "the prudent man looks where he is going." "Keep sane and sober for your prayers." Prudence is "right reason in action," writes St. Thomas Aquinas, following Aristotle. It is not to be confused with timidity or fear, nor with duplicity or dissimulation. It is called auriga virtutum (the charioteer of the virtues); it guides the other virtues by setting rule and measure. It is prudence that immediately guides the judgment of conscience. The prudent man determines and directs his conduct in accordance with this judgment. With the help of this virtue we apply moral principles to particular cases without error and overcome doubts about the good to achieve and the evil to avoid.
