Catholic Catechism on Married Love

Catholics have a lot of things going for them. Sometimes they even say really beautiful things, like this bit from the Catechism, the authoritative book of Catholic teaching:

It can seem difficult, even impossible, to bind oneself for life to another human being. This makes it all the more important to proclaim the Good News that God loves us with a definitive and irrevocable love, that married couples share in this love, that it supports and sustains them, and that by their own faithfulness they can be witnesses to God’s faithful love. (Catechism of the Catholic Church, §1648)
