Catechism of the Catholic Church #1661:
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 their way to eternal life.
     If you would like to book a marriage service in the Church, then please contact the Parish Priest as early as possible (always at least 3 months beforehand), and ask for an appointment to discuss marriage preparation and practical arrangements
