At each service daily, a prayer, or 'collect' is used from the Book of Common Prayer. The collect for this week, the seventh Sunday after Trinity is:
LORD of all power and might, who art the author and giver of all good things; Graft in our hearts the love of thy Name, increase in us true religion, nourish us with all goodness, and of thy great mercy keep us in the same; through Jesus Christ our Lord. Amen.
