Catholics generally view St. Michael the Archangel as the leader of God’s army. He is commonly described in Catholic tradition as the prince or commander of the heavenly host, especially in spiritual battle.

Quick note

This is the standard Catholic answer:

  • St. Michael = leader of the army of God.
  • He is especially associated with defending against evil and serving as a protector of the Church.

Why Michael

Catholic sources and devotional tradition connect Michael with the battle in heaven and his role as a defender of God’s people. His name is often understood as expressing loyalty to God, which fits that role.

TL;DR: The archangel is Michael.
