This prayer has been written for Kate and Wills for their marriage and can be used by anyone getting married.

But when I read it out loud to Joan we both laughed at the phrase ‘strengthen their wills’. Wouldn’t resolve have been a better word’

From the article:-
It asks God to “look in favour on William and Catherine and all who are made one in marriage”.
The full text of the prayer reads: “God of all grace, friend and companion, look in favour on William and Catherine and all who are made one in marriage.
“In your love deepen their love and strengthen their wills to keep the promises they will make, that they may continue in life-long faithfulness to each other; through Jesus Christ our Lord. Amen.”

This prayer comes at the end of an article about Kate Middleton being confirmed in the CofE.
