and direct our hearts
through Jesus Christ
in the unity of the Holy Spirit,
one God, now and for ever.
Amen.
The above is my reworking for my Book of Prayers in Common in which I seek to provide a set of collects with history and commentary.
Christians have been praying this collect, on the equivalent of the Seventh Sunday of Easter for at least 12 centuries. It has not been used much in post-Reformation churches, and after Vatican II it was moved to the Twenty-Ninth Sunday in Ordinary Time in the Roman Rite. But it still fits fine in its historic position.
