Chapter 3: THE SACRAMENTS AT THE SERVICE OF COMMUNION
The sacrament of Matrimony signifies the union of Christ and the Church. It gives spouses the grace to love each other with the love with which Christ has loved his Church; the grace of the sacrament thus perfects the human love of the spouses, strengthens their indissoluble unity, and sanctifies them on the way to eternal life (cf Council of Trent: DS 1799).
