St. Michael medal with an image of St. Michael the Archangel on the back.
St. Michael is the patron saint of the military, police officers and law enforcement.
St. Michael is invoked for protection, especially from lethal enemies. He is also the patron of soldiers, police and doctors. St. Michael has four main responsibilities or offices, as we know from scripture and Christian tradition:
Combat Satan
Escort the faithful to heaven at their hour of death
Be a champion of all Christians, and the Church itself
Call men from life on Earth to their heavenly judgment.
