St. Michael is perhaps the most invoked archangel. Depicted as a warrior wearing armor and brandishing a sword, he has a formidable presence in art and in the spiritual realm. He is known for his appearance in the Book of Revelation, leading God’s armies against Satan’s forces during the apocalyptic war in heaven. Many parishes will pray the St. Michael Prayer after Mass, a powerful invocation that calls on the archangel to “defend us in battle” and “be our protection against the wickedness and snares of the devil.” Find more prayers to St. Michael and the heavenly host in “St. Michael and the Angels: A Month with St. Michael and the Holy Angels” compiled by TAN Books.
