In the marriage covenant, a man and woman form
an intimate communion of life and love with each other.
-Catechism of the Catholic Church
O God, you have forged the covenant of marriage
as a sweet yoke of harmony
and an unbreakable bond of peace,
so that the chaste and fruitful love of holy Matrimony
may serve to increase the children you adopt as your own.
-Nuptial Mass
