8. Use sacramentals
Correct use of sacramentals can be very effective in the fight against the devil, particularly, for example, the brown scapular, St. Benedict’s medal, and holy water
9. Call on St. Michael the Archangel
In our battle against Satan, we should use every weapon. God chose St. Michael the Archangel as a faithful angel, prince of the heavenly army, to cast into hell Lucifer and the other rebellious angels. St. Michael, whose name means “Who is like God?” is as powerful today as he was then.
