St Michael, who ranks among the seven archangels, is also one of the three angels mentioned by name in the Scriptures.
St Michael is spoken of four times in the Scriptures:
Because of the victory, St Michael is revered in Catholic tradition and liturgy as the protector of the Church, as once he was regarded as the protector of the Israelites. In the Eastern Church, St Michael is placed over all the angels, as prince of the Seraphim.
He is usually represented in a sword and banner. His feast day is 29 September.
Pope Leo XIII decreed that after all masses the following prayer should be recited to protect the Church from the sins of Modernism. This requirement was made optional in the 1960s.
Saint Michael, the Archangel,
Defend us in the hour of battle,
keep us safe from the wickedness and snares of the Devil,
May God restrain him, we humbly pray,
and do thou, O Prince of the Heavenly Host,
By the power of God, cast Satan down into Hell,
and with him all the evil spirits
who wander through the world for the ruin of souls.
Many continue to recite this prayer at the conclusion of the Rosary, and in times of great temptation.
