O Almighty and merciful God, who hast commissioned Thy angels to guide and protect us, command them to be our assiduous companions from our setting out until our return; to clothe us with their invisible protection; to keep from us all danger of collision, of fire, of explosion, of fall and bruises, and finally, having preserved us from all evil, and especially from sin, to guide us to our heavenly home. Through Jesus Christ, our Lord. Amen.
