The following prayer for engaged couples is taken from Before “I Do”, a Catholic marriage preparation program booklet. 

Lord, send out your Spirit
and renew the face of the earth.
Father, Jesus gave his life
because he loved deeply and completely.
May our love for one another
be all encompassing and all consuming.
Make our love be pleasurable.
Make it be as creative as it is stable,
as passionate as it is respectful,
as gentle as it is strong,
so that all who know us will see in our
love the hand of you, our creator.
If and when we are blessed with children,
may they thrive in the passionate and energizing love
that has its beginning in the love you have for the world
and all its peoples.
We ask this through, Jesus, our Lord and brother.
Amen.
