It is an intimate union in which the spouses give themselves, as equal persons, completely and lovingly to one another. These biblical passages help us to appreciate God's plan for marriage.

For this reason a man shall leave his father and mother, and the two shall become one flesh'" (Mk 10:6-8). Jesus reiterates these teachings from Genesis, saying, "But from the beginning of creation, 'God made them male and female. God blesses the man and woman and commands them to "be fertile and multiply" (Gn 1:28). The man recognizes the woman as "bone of my bones and flesh of my flesh" (Gn 2:23).

A man "leaves his father and mother and clings to his wife, and the two of them become one body" (Gn 2:24).

Marriage,as instituted by God, is a faithful, exclusive, lifelong union of a man and a woman joined in an intimate community of life and love. We, the Catholic bishops of the United States, offer here some basic truths to assist people in understanding Catholic teaching about marriage and to enable them to promote marriage and its sacredness. This kind of reflection, using reason and faith, is an appropriate starting point and framework for the current debate. This situation challenges Catholics-and all who seek the truth-to think deeply about the meaning of marriage, its purposes, and its value to individuals, families, and society. A growing movement today favors making those relationships commonly called same-sex unions the legal equivalent of marriage.
