The teachings of the Catholic Church on marriage might be summarized in the following points:
Weekly Meditation: Vowed Fidelity to One Another
The Catholic Church teaches that marriage is a permanent and lifelong union between a man and a woman. It’s something done for the benefit of each person, but it’s also directed to the common good of the human community. The sacrament of marriage takes this human commitment and makes it the focus of God’s ongoing renewal of human life through the ministry of Christ and Christ’s body, the Church. When two Christians give their lives to one another, they become a living example of how God is redeeming the world. The love that grows in marriage shows us the love that God has for the whole world.
The sacrament of marriage is how women and men follow Jesus in the context of world and family. The married life is a source of God’s gift of friendship and blessing, not just for its own sake, but for the sake of the world. Marriage is fruitful: it generates love and reconciliation and peace and growth. It does this by providing daily opportunities for pleasure, for gratitude, for enjoyment; but also opportunities for conflict, suffering, and hard work. As a way of following Jesus, marriage invites us to participate in Christ’s journey to the cross for the sake of our resurrection. Marriage makes us better people, not just in the home, but out in the world.
Marriage is the life that follows when two people live in the vows of lifelong fidelity that they promised one another. The joys and sufferings of marriage, when they take place within personal and permanent fidelity, become a clear image of how God restores creation. In this way, married people again are an icon of God's faithfulness to his people and Christ's love for his church. The sacrament of marriage comes in to being when Christ's own faithfulness is recognized and celebrated within the faithfulness of the spouses.
