O God, the author of peace and lover of concord, whose heart is glad when all your children live together in unity; we lift to you the grief of our hearts, hoping that you will not only comfort those hearts, but change them; that we may be the people you have created, and called us to be; through Jesus Christ our Lord. Amen.
