Gen 2, 24 And the two of them become one body

(Gen 2, 24) And the two of them become one body

[24] That is why a man leaves his father and mother and clings to his wife, and the two of them become one body.

(CCC 1644) The love of the spouses requires, of its very nature, the unity and indissolubility of the spouses' community of persons, which embraces their entire life: "so they are no longer two, but one flesh" (Mt 19:6; cf. Gen 2:24). They "are called to grow continually in their communion through day-to-day fidelity to their marriage promise of total mutual self-giving" (FC 19). This human communion is confirmed, purified, and completed by communion in Jesus Christ, given through the sacrament of Matrimony. It is deepened by lives of the common faith and by the Eucharist received together. (CCC 2334) "In creating men 'male and female,' God gives man and woman an equal personal dignity" (FC 22; Cf. GS 49 § 2). "Man is a person, man and woman equally so, since both were created in the image and likeness of the personal God" (MD 6). (CCC 2335) Each of the two sexes is an image of the power and tenderness of God, with equal dignity though in a different way. The union of man and woman in marriage is a way of imitating in the flesh the Creator's generosity and fecundity: "Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh" (Gen 2:24). All human generations proceed from this union (Cf. Gen 4:1-2, 25-26; 5:1).
