Lumen Christi’s mascot is the Archangel. The Catechism of the Catholic Church (334-336) states, “the whole life of the Church benefits from the mysterious and powerful help of angels. From its beginning until death, human life is surrounded by their watchful care and intercession. Besides each believer stands an angel as protector and shepherd leading him to life. Already here on earth the Christian life shares by faith in the blessed company of angels and men united in God”
St. Michael is the leader of all the angels and so earns the title, “Archangel.” He has four main responsibilities including combatting Satan, escorting the faithful to heaven at the hour of death, be a champion of all Christians, and finally to call all people from their life on Earth to heavenly judgment. Today, St. Michael is often called upon for protection. At Lumen, our students end our day in prayer to the angel above all other angels, St. Michael the Archangel.

Our School Prayer
Saint Michael the Archangel, defend us in battle,
be our protector against the wickedness 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,
Cast into hell, Satan and all the evil spirits
who prowl around the Earth seeking the ruins of souls.
