Saint Michael in the Catholic Church

Saint Michael the Archangel is referenced in the Old Testament and has been part of Christian teachings since the earliest times. In Catholic writings and traditions, he acts as the defender of the Church and the opponent of Satan. He also assists people at the hour of death.

A widely used "Prayer to Saint Michael" was brought into official use by Pope Leo XIII in 1886 and was recommended by Pope John Paul II in 1994.
