Seán Manchester (from his writings) on prayers for protection:
(Saint Michael the Archangel, defend us in battle, be our protection against the malice and snares of the Devil. May God rebuke him we humbly pray; and do thou, O Prince of the Heavenly host, by the power of God, thrust into hell Satan and all evil spirits who wander through the world for the ruin of souls. Amen.)
Almighty God, heavenly Father, breathe Your Holy Spirit into the heart of this Your servant [NAME] and inspire [HIM/HER] with love for goodness and truth. May [HE/SHE], fearing only You, have no other fear; knowing Your compassion, be ever mindful of Your love; and serving You faithfully unto death, live eternally with You; through Jesus Christ our Lord. Amen.
O divinum Cor Iesu, praesta, quaesumus, animabus purgantibus requiem aeternam, morituris gratiam finalem, peccatoribus veram paenitentiam, paganis fidei lucem, nobis nostrisque omnibus tuam benedictionem. Tibi ergo, Cor Iesu piissimum, omnes has animas commendimus et pro ipsis tibi offerimus omnia merita sacri Cordis tui. Amen.
(O Lord Jesus Christ, who have said: Ask and you shall receive, seek and you shall find, knock and it shall be opened unto you; mercifully attend to our supplications, and grant us the gift of Your divine charity, that we may ever love You with our whole heart and with all our words and deeds, and may never cease from praising You. Amen.)
