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 us from all unreasoblge danger; 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.
