The Book of Revelation paints the scene:
"Now war arose in heaven, Michael and his angels fighting against the dragon..." (Revelation 12:7).
Catholic tradition tells us that the dragon was none other than Lucifer—once the brightest of all angels. When God asked the angels to serve, Lucifer rebelled. His response: Non serviam!—"I will not serve".
At that moment, Michael, whose name means "Who is like God?", stood up. He wasn’t the most powerful angel. In fact, tradition says he was of a lower rank. But he was the most loyal. His cry—Quis ut Deus? ("Who is like God?")—was a direct rebuke to Lucifer’s pride. No one is like God. And so began the battle that cast Lucifer and his followers from heaven.
Serviam is Latin for "I will serve." Catholic tradition claims that this was Michael’s answer to Lucifer’s rebellion. It’s not found word-for-word in Scripture, but its spirit runs through the entire biblical story.
"Serviam" is more than an answer; it’s a pledge. It means choosing God’s will over our own pride. It means humility, trust, and courage. As one writer put it, "The Archangel Michael loyally defended God with his cry of 'Serviam' and vanquished Lucifer to Hell with all his demons".
A priest in Chicago tells this story:
As a young seminarian, he was haunted by doubts and spiritual dryness. One morning, after repeating "Serviam" under his breath, he felt a sudden peace. Years later, he taught his parishioners to do the same—whenever faced with temptation or discouragement, say, "Serviam!" and recall St. Michael’s courage.
The Ursuline Sisters, whose schools worldwide bear the motto "Serviam," have inspired countless students to serve God and neighbor. For them, every act of kindness echoes Michael’s ancient stand.
Many Catholics begin their day with a simple "Serviam" as a morning offering:
"Lord, today I will serve. Help me to love and serve you faithfully."
When temptation strikes, saying "Serviam" is a quick and powerful reminder of who we are and whose we are. It’s a way to reorient our hearts toward God, just as Michael did in heaven.
"Serviam, Lord!"
—Catholic tradition, echoing St. Michael.
Prayer to St. Michael
St. 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 thou, O Prince of the Heavenly Hosts,
by the power of God,
cast into Hell Satan, and all the evil spirits,
who prowl about the world seeking the ruin of souls. Amen.
Although the words "Serviam" and "Non serviam" are not found directly in the Bible, they are central to Catholic teaching about the angels’ rebellion. The story is rooted in Revelation 12, which describes the war in heaven, and in centuries of Christian tradition.
Michael’s role as a protector appears throughout history. He is invoked in times of trouble, painted in churches and cathedrals, and remembered every September 29th on the Feast of the Archangels.
Modern Catholics face new battles—pride, selfishness, despair. The motto "Serviam" is not just about resisting evil, but about actively choosing God, over and over, in every small act of love, every sacrifice, every moment of faith.
When we say "Serviam," we join St. Michael—not in some distant celestial battle, but in daily life: at work, at home, in church, on the street. His cry—"Who is like God?"—becomes our own.
The story of St. Michael and Lucifer isn’t just an ancient legend. It’s a mirror for every Christian. The choice between pride and service, rebellion and surrender, is made in countless small ways, every day.
Every time we say "Serviam," we stand with Michael, choosing faith over pride, and service over rebellion.
"Serviam, Lord!" May this be our cry, today and always.
