“The vocation to marriage is written in the very nature of man and woman as they came from the hand of the Creator.” “The sacrament of Matrimony…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.” CCC Part II, Art. VII
