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."¹²⁰ Gen 2:24. All human generations proceed from this union.¹²¹ Cf. Gen 4:1-2, 25-26; 5:1.
