Some background regarding the prayer:
The prayer to St. Michael originated with Pope Leo XIII in 1886. Legend has it that the Pope, following Holy Mass, received a vision in which he saw the great damage Satan would do to the Church and the world in the 20th century. Pope Leo XIII composed this prayer in response and added it to the Leonnine prayers to be recited after Low Mass, which were originally intended for the intentions of the defense of the temporal sovereignty of the Holy See.
