Heb 12, 16 No one be an immoral or profane person

(Heb 12, 16) No one be an immoral or profane person

[16] that no one be an immoral or profane person like Esau, who sold his birthright for a single meal.

(CCC 1852) There are a great many kinds of sins. Scripture provides several lists of them. The Letter to the Galatians contrasts the works of the flesh with the fruit of the Spirit: "Now the works of the flesh are plain: fornication, impurity, licentiousness, idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, factions, envy, drunkenness, carousing, and the like. I warn you, as I warned you before, that those who do such things shall not inherit the Kingdom of God" (Gal 5:19-21; cf. Rom 1:28-32; 1 Cor 9-10; Eph 5:3-5; Col 3:5-8; 1 Tim 9-10; 2 Tim 2-5). (CCC 2353) Fornication is carnal union between an unmarried man and an unmarried woman. It is gravely contrary to the dignity of persons and of human sexuality which is naturally ordered to the good of spouses and the generation and education of children. Moreover, it is a grave scandal when there is corruption of the young. (CCC 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 (Cf. FC 81). 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. (CCC 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" (CDF, Persona humana 7). 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) Cf. FC 80).
