Today’s Catechism sections continue the discussion on offenses against marriage. Supporting material comes from the Apostolic Exhortation, “Familiaris Consortio”.

Other offenses against the dignity of marriage

2387 The predicament of a man who, desiring to convert to the Gospel, is obliged to repudiate one or more wives with whom he has shared years of conjugal life, is understandable. However polygamy is not in accord with the moral law." [Conjugal] communion is radically contradicted by polygamy; this, in fact, directly negates the plan of God which was revealed from the beginning, because it is contrary to the equal personal dignity of men and women who in matrimony give themselves with a love that is total and therefore unique and exclusive."179 The Christian who has previously lived in polygamy has a grave duty in justice to honor the obligations contracted in regard to his former wives and his children.

2388 Incest designates intimate relations between relatives or in-laws within a degree that prohibits marriage between them.180 St. Paul stigmatizes this especially grave offense: "It is actually reported that there is immorality among you . . . for a man is living with his father's wife.... In the name of the Lord Jesus ... you are to deliver this man to Satan for the destruction of the flesh...."181 Incest corrupts family relationships and marks a regression toward animality.

2389 Connected to incest is any sexual abuse perpetrated by adults on children or adolescents entrusted to their care. The offense is compounded by the scandalous harm done to the physical and moral integrity of the young, who will remain scarred by it all their lives; and the violation of responsibility for their upbringing.

2390 In a so-called free union, a man and a woman refuse to give juridical and public form to a liaison involving sexual intimacy.

The expression "free union" is fallacious: what can "union" mean when the partners make no commitment to one another, each exhibiting a lack of trust in the other, in himself, or in the future?

The expression covers a number of different situations: concubinage, rejection of marriage as such, or inability to make long-term commitments.182 All these situations offend against the dignity of marriage; they destroy the very idea of the family; they weaken the sense of fidelity. They are contrary to the moral law. The sexual act must take place exclusively within marriage. Outside of marriage it always constitutes a grave sin and excludes one from sacramental communion.

2391 Some today claim a "right to a trial marriage" where there is an intention of getting married later. However firm the purpose of those who engage in premature sexual relations may be, "the fact is that such liaisons can scarcely ensure mutual sincerity and fidelity in a relationship between a man and a woman, nor, especially, can they protect it from inconstancy of desires or whim."183 Carnal union is morally legitimate only when a definitive community of life between a man and woman has been established. Human love does not tolerate "trial marriages." It demands a total and definitive gift of persons to one another.184

IN BRIEF

2400 Adultery, divorce, polygamy, and free union are grave offenses against the dignity of marriage.

The Apostolic Exhortation “Familiaris Consortio” by Pope John Paul II discusses “trial marriages”.

a) Trial Marriages

80. A first example of an irregular situation is provided by what are called "trial marriages," which many people today would like to justify by attributing a certain value to them. But human reason leads one to see that they are unacceptable, by showing the unconvincing nature of carrying out an "experiment" with human beings, whose dignity demands that they should be always and solely the term of a self-giving love without limitations of time or of any other circumstance.

The Church, for her part, cannot admit such a kind of union, for further and original reasons which derive from faith. For, in the first place, the gift of the body in the sexual relationship is a real symbol of the giving of the whole person: such a giving, moreover, in the present state of things cannot take place with full truth without the concourse of the love of charity, given by Christ. In the second place, marriage between two baptized persons is a real symbol of the union of Christ and the Church, which is not a temporary or "trial" union but one which is eternally faithful. Therefore between two baptized persons there can exist only an indissoluble marriage.

Such a situation cannot usually be overcome unless the human person, from childhood, with the help of Christ's grace and without fear, has been trained to dominate concupiscence from the beginning and to establish relationships of genuine love with other people. This cannot be secured without a true education in genuine love and in the right use of sexuality, such as to introduce the human person in every aspect, and therefore the bodily aspect too, into the fullness of the mystery of Christ.

It will be very useful to investigate the causes of this phenomenon, including its psychological and sociological aspect, in order to find the proper remedy.
