For Catholics, the Sacrament of Marriage, or Holy Matrimony, is a public sign that one gives oneself totally to this other person. It is also a public statement about God: the loving union of husband and wife speaks of family values and also God's values.

God calls most men and women to the married vocation. This is a great honor and an immense challenge. To fulfill this marvelous calling we need Christ's help; we need his Spirit's power.

Marriage between a man and a woman is at the heart of God's design for creation. In the first creation story we find man and woman as the crown of God's good creation. "Then God said, 'Let us make humankind in our own image, according to our likeness; and let them have dominion over the fish of the sea, and over the birds of the air, and over the cattle, and over all the wild animals of the earth, and over every creeping thing that creeps upon the earth.' So God created humankind in his image, in the image of God he created them; male and female he created them" (Gen 1:26-27). Moreover, God "blessed" them and said, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth" (Gen 1:28). Here God revealed that marriage, sexuality, and family life are not meant to be just biological and evolutionary phenomenon, but are integral to his purposes, part of his plan for the human race created in his own image and likeness.
