At each service daily, a prayer, or 'collect' is used from the Book of Common Prayer. The collect for this week the Third Sunday after Trinity is:
O LORD, we beseech thee mercifully to hear us; and grant that we, to whom though hast given an hearty desire to pray, may by thy mighty aid be defended and comforted in all dangers and adversities; through Jesus Christ our Lord. Amen.
