Wonderful Saintly Founder
of the eloquent Order of Preachers
and friend of Saint Francis of Assisi,
you were a fiery defender of the Faith
and a fighter against the darkness of heresy.
You resembled a great star that shone
close to the world and pointed to the Light
which was Christ.
Help astronomers to study the stars
and admire their wonderful Maker,
proclaiming: "Give glory to God in the highest."

Amen.
