Unlike most other Christian Churches, Marriage in the Catholic Church is a sacrament and means much more than just a contract between a man and a women. Two non-Catholics cannot receive this Catholic sacrament.
The Catholic Church believes that God himself is the author of marriage and has created it for one man and one woman.
The spouses of a valid marriage:
• Create a bond, which by its very nature is perpetual and exclusive.
• Are strengthened and consecrated for the duties and the dignity of their state.
• Are sealed by God himself in their consent to mutually give and receive one another.
• Form a covenant that is integrated into God's covenant with man: "Authentic married love is caught up into divine love."
• Have their own special grace that:
. • Perfects the couple's love.
. • Strengthens their unity.
. • Helps one another to attain holiness in their married life.
. • Helps in welcoming and educating their children.
