I have found the 2004 Book of Common Prayer of the Church of Ireland online in PDF format. The Irish outdid themselves. One of their liturgies is “A Late Evening Office,” from which I take the following prayer verbatim.
KRT
+++++++++++++++++++++++++++++++
Lord Almighty,
come and scatter the darkness of our hearts
by the light of your presence;
that we may know you
the Light of the world
and the one true God,
blessed this night and forevermore. Amen.
