I was thinking more about this, and about how some prayers are poetry in and of themselves, if you slough away the heavy chains of association with man's religious prejudices.
Raised a Roman Catholic, my childhood was sprinkled with learning and 'reciting' prayers. I wondered what poem I could rescue from a selection of prayers that I know so well. I chose seven: the 'Our Father', the 'Creed', the 'St Patrick's Breastplate', a 'Guardian Angel' prayer, the 'Salve Regina', Psalm 23 ('The Lord is my Shepherd') and the 'Act of Contrition'. To be consistent I took the text from here.
you are the banished
Almighty guide descended
eyes of earth toward evil resolve.
In the darkest valley of temptation
a quiet stranger
sighs,
dies.
Spirit me to forgiveness
beside rose waters,
beneath the light of grace,
behind gracious power;
restore me to hope
above buried heaven
near a hallowed presence
through days of mercy;
lead me to believe
that the worthy shall lead,
that a god shall comfort,
that tears for a mother and father
are tears of an angel,
that to walk above waters
is communion with earth
and that when life and light are done
I shall come
in from exile.
