This was the prayer for the morning prayers in Phyllis Tickle’s Divine Hours, originally in The Book of Common Prayer:
O God, you have taught me to keep all your commandments by loving you and
my neighbor: Grant me the grace of your Holy Spirit, that I may be devoted to
you with my whole heart, and united to others with pure affection; through
Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one
God, for ever and ever. Amen.?
