Q. What is the sacrament of Matrimony?

A. The Sacrament of Matrimony is the Sacrament that unites a Christian man and woman in lawful marriage. 1

The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament. 2
