LIFE IN CHRIST
THE TEN COMMANDMENTS
"YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF"
THE NINTH COMMANDMENT
You shall not covet your neighbor's house; you shall not covet your neighbor's wife, or his
manservant, or his maidservant, or his ox, or his ass, or anything that is your neighbor's.299
Every one who looks at a woman lustfully has already committed adultery with her in his
2514 St. John distinguishes three kinds of covetousness or concupiscence: lust of the flesh, lust of the
eyes, and pride of life.301 In the Catholic catechetical tradition, the ninth commandment forbids carnal
concupiscence; the tenth forbids coveting another's goods.
2515 Etymologically, "concupiscence" can refer to any intense form of human desire. Christian
theology has given it a particular meaning: the movement of the sensitive appetite contrary to the
operation of the human reason. The apostle St. Paul identifies it with the rebellion of the "flesh"
against the "spirit."302 Concupiscence stems from the disobedience of the first sin. It unsettles man's
moral faculties and, without being in itself an offense, inclines man to commit sins.303
2516 Because man is a composite being, spirit and body, there already exists a certain tension in him; a
certain struggle of tendencies between "spirit" and "flesh" develops. But in fact this struggle belongs to
the heritage of sin. It is a consequence of sin and at the same time a confirmation of it. It is part of the
daily experience of the spiritual battle:
For the Apostle it is not a matter of despising and condemning the body which with the spiritual
soul constitutes man's nature and personal subjectivity. Rather, he is concerned with the
morally good or bad works, or better, the permanent dispositions - virtues and vices - which are
the fruit of submission (in the first case) or of resistance (in the second case) to the saving
action of the Holy Spirit. For this reason the Apostle writes: "If we live by the Spirit, let us also
walk by the Spirit."304
I. PURIFICATION OF THE HEART
2517 The heart is the seat of moral personality: "Out of the heart come evil thoughts, murder,
adultery, fornication. . . . "305 The struggle against carnal covetousness entails purifying the heart and
Remain simple and innocent, and you will be like little children who do not know the evil that
destroys man's life.306
2518 The sixth beatitude proclaims, "Blessed are the pure in heart, for they shall see God."307 "Pure in
heart" refers to those who have attuned their intellects and wills to the demands of God's holiness,
chiefly in three areas: charity;308 chastity or sexual rectitude;309 love of truth and orthodoxy of faith.310
There is a connection between purity of heart, of body, and of faith:
The faithful must believe the articles of the Creed "so that by believing they may obey God, by
obeying may live well, by living well may purify their hearts, and with pure hearts may
understand what they believe."311
2519 The "pure in heart" are promised that they will see God face to face and be like him.312 Purity of
heart is the precondition of the vision of God. Even now it enables us to see according to God, to
accept others as "neighbors"; it lets us perceive the human body - ours and our neighbor's - as a
temple of the Holy Spirit, a manifestation of divine beauty.
II. THE BATTLE FOR PURITY
2520 Baptism confers on its recipient the grace of purification from all sins. But the baptized must
continue to struggle against concupiscence of the flesh and disordered desires. With God's grace he
- by the virtue and gift of chastity, for chastity lets us love with upright and undivided heart;
- by purity of intention which consists in seeking the true end of man: with simplicity of vision, the
baptized person seeks to find and to fulfill God's will in everything;313
- by purity of vision, external and internal; by discipline of feelings and imagination; by refusing all
complicity in impure thoughts that incline us to turn aside from the path of God's commandments:
"Appearance arouses yearning in fools";314
- by prayer:
I thought that continence arose from one's own powers, which I did not recognize in myself. I
was foolish enough not to know . . . that no one can be continent unless you grant it. For you
would surely have granted it if my inner groaning had reached your ears and I with firm faith
had cast my cares on you.315
2521 Purity requires modesty, an integral part of temperance. Modesty protects the intimate center of
the person. It means refusing to unveil what should remain hidden. It is ordered to chastity to whose
sensitivity it bears witness. It guides how one looks at others and behaves toward them in conformity
with the dignity of persons and their solidarity.
2522 Modesty protects the mystery of persons and their love. It encourages patience and moderation
in loving relationships; it requires that the conditions for the definitive giving and commitment of man
and woman to one another be fulfilled. Modesty is decency. It inspires one's choice of clothing. It
keeps silence or reserve where there is evident risk of unhealthy curiosity. It is discreet.
2523 There is a modesty of the feelings as well as of the body. It protests, for example, against the
voyeuristic explorations of the human body in certain advertisements, or against the solicitations of
certain media that go too far in the exhibition of intimate things. Modesty inspires a way of life which
makes it possible to resist the allurements of fashion and the pressures of prevailing ideologies.
2524 The forms taken by modesty vary from one culture to another. Everywhere, however, modesty
exists as an intuition of the spiritual dignity proper to man. It is born with the awakening consciousness
of being a subject. Teaching modesty to children and adolescents means awakening in them respect
for the human person.
2525 Christian purity requires a purification of the social climate. It requires of the communications
media that their presentations show concern for respect and restraint. Purity of heart brings freedom
from widespread eroticism and avoids entertainment inclined to voyeurism and illusion.
2526 So called moral permissiveness rests on an erroneous conception of human freedom; the
necessary precondition for the development of true freedom is to let oneself be educated in the moral
law. Those in charge of education can reasonably be expected to give young people instruction
respectful of the truth, the qualities of the heart, and the moral and spiritual dignity of man.
2527 "The Good News of Christ continually renews the life and culture of fallen man; it combats and
removes the error and evil which flow from the ever-present attraction of sin. It never ceases to purify
and elevate the morality of peoples. It takes the spiritual qualities and endowments of every age and
nation, and with supernatural riches it causes them to blossom, as it were, from within; it fortifies,
completes, and restores them in Christ."316
2528 "Everyone who looks at a woman lustfully has already committed adultery with her in his heart"
2529 The ninth commandment warns against lust or carnal concupiscence.
2530 The struggle against carnal lust involves purifying the heart and practicing temperance.
2531 Purity of heart will enable us to see God: it enables us even now to see things according to God.
2532 Purification of the heart demands prayer, the practice of chastity, purity of intention and of
2533 Purity of heart requires the modesty which is patience, decency, and discretion. Modesty
protects the intimate center of the person.
