I posted an excerpt of this last week; here's the whole thing.
Let us pray.
Eternal God, creator and preserver of all life, author of salvation, and giver of all grace: Look with favor upon the world you have made, and for which your Son gave his life, and especially upon this man and woman whom you make one flesh in Holy Matrimony. Amen.
Give them wisdom and devotion in the ordering of their common life, that each may be to the other
a strength in need, a counselor in perplexity, a comfort in sorrow, and a companion in joy. Amen.
Grant that their wills may be knit together in your will, and their spirits in your Spirit, that they may grow in love and peace with you and one another all the days of their life. Amen.
Give them grace, when they hurt each other, to recognize and acknowledge their fault, and to seek each other's forgiveness and yours. Amen.
Make their life together a sign of Christ's love in this sinful and broken world, that unity may overcome estrangement, forgiveness heal guilt, and joy conquer despair. Amen.
Bestow on them, if it is your will, the gift and heritage of children, and the grace to bring them up to know you, to love you, and to serve you. Amen.
Give them such fulfillment of their mutual affection that they may reach out in love and concern for others. Amen.
