From the Book of Common Prayer:
Gracious Father, we pray for your holy catholic Church. Fill it
with all truth, in all truth with all peace. Where it is corrupt,
purify it; where it is in error, direct it; where in any thing it is
amiss, reform it. Where it is right, strengthen it; where it is in
want, provide for it; where it is divided, reunite it; for the sake
of Jesus Christ thy Son our Savior. Amen. (BCP)
