Protection in this life and to be conducted to the presence of God in Heaven
From the Novena to St. Michael the Archangel
Sacred Scripture: Revelation 12:7-12
Meditation for Day 9
The Angels, the lowest and nearest choir to humanity, are our constant companions in the spiritual life; through their intercession, we ask St. Michael to guard us now and conduct us safely into God's presence at the hour of death. The Church's liturgy for the dead long invoked St. Michael as the bearer of souls into holy light — May Michael, the standard-bearer, lead them into holy light. Revelation celebrates the victory of heaven: Now the salvation and the power and the kingdom of our God and the authority of his Christ have come (Rev 12:10). As this novena ends on the eve of his feast, entrust your whole life — and your death — into the hands of this great Prince, and ask him to stand beside you in that final hour.Daily Novena Prayer (recited every day)
Closing Prayer
O glorious prince St. Michael, chief and commander of the heavenly hosts, guardian of souls, vanquisher of rebel spirits, servant in the house of the Divine King and our admirable conductor, you who shine with excellence and superhuman virtue deliver us from all evil, who turn to you with confidence and enable us by your gracious protection to serve God more and more faithfully every day. Pray for us, O glorious St. Michael, Prince of the Church of Jesus Christ, that we may be made worthy of His promises. Almighty and Everlasting God, Who, by a prodigy of goodness and a merciful desire for the salvation of all men, has appointed the most glorious Archangel St. Michael Prince of Your Church, make us worthy, we ask You, to be delivered from all our enemies, that none of them may harass us at the hour of death, but that we may be conducted by him into Your Presence. This we ask through the merits of Jesus Christ Our Lord. Amen.
Concluding prayers: Many novena traditions add one Our Father, one Hail Mary, and one Glory Be at the close of each day's prayer.
