May the Cross of Christ guard, protect and deliver you.

May the Cross of the Son of God,

which is mightier than all the hosts of satan

and more glorious than all the hosts of heaven,

abide with you 
in your going out and your coming in.

By day and night, 
at morning and at evening, 

at all times and in all places 
may it protect and defend you.

From the wrath of evildoers,

from the assaults of evil spirits

from foes visible and invisible

from the snares of the devil,

from all passions that beguile the soul and body:

May the Cross of Christ 
guard, protect and deliver you. 
Amen.
