Christian marriage, or Holy Matrimony, is a lifelong covenant between one man and one woman, uniting them in self-giving love, joy, and faithfulness. It is ordained by God for the procreation and spiritual nurture of children, the sanctification of husband and wife, the mutual support of their common life, and the flourishing of family, church, and society. Husband and wife enter into this covenant by exchanging vows before God and in the presence of witnesses.
