Saint Michael the Archangel, defend us in battle; be our protection against the wickedness and snares of the devil. May God rebuke him, we humbly pray; and do you, O Prince of the Heavenly Hosts, by the power of God, cast into hell satan and all the evil spirits who wander through the world seeking the ruin of souls. Amen.
"Put you on the armor of God, that you may be able to stand against the deceits of the devil. For we are not fighting against human beings but against the wicked spiritual forces in the heavenly world, the rulers, authorities, and cosmic powers of this dark age. Therefore take the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand." (Ephesians 6:11-13)
"For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord." (Romans 8:38-39)
"Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people."(Ephesians 6:14-18)
