From The Long Lost Friend:
Our dear Lord Jesus Christ going on a journey, saw a firebrand burning; it was Saint Lorenzo stretched out on a roast. He rendered him assistance and consolation; he lifted his divine hand and blessed the brand; he stopped it from spreading deeper and wider. Thus may the burning be blessed in the name of God the Father, Son and Holy Ghost. Amen.
