Let us pray. O God, who allayed the flames of fire for three children: grant in your mercy; that the flame of vice may not consume us your servants. Direct, we beseech you, Lord, our actions by your inspirations and further them by your assistance: so that every word and work of ours may begin always from you and by you be likewise ended. Quench in us, we beseech you, Lord, the flame of vice, even as you enabled blessed Lawrence to overcome his fire of sufferings. Through Christ our Lord.
R. Amen.
