May 8 Feast of the Apparition of St. Michael (victory)
While St. Michaels' Feast Day is September 29, the feast of the Apparition of Saint Michael on May 8 commemorates the 6th century appearance of the archangel on Mount Gargano near Manfredonia in southern Italy. A church was built in his honor at the site. Medals or holy cards with 'relics' of Michael are probably rock chips from the cave where he appeared or pieces of cloth that have touched it.
Almighty God, Saint Michael led the army of angels
that defeated Satan and the demons when they rebelled against You. Because his
name means "Who is like God," Pope Saint Gregory the Great said,
"Whenever some act of wondrous power must be performed, Michael is sent,
so that his action and his name may make it clear that no one can do what God
does by his superior power." I ask Saint Michael to lead an army of
angels in my defense whenever I am being seduced by Satan's wiles or crushed
by the weight of his evil power. You, O Lord, are always victorious in my
life! Saint Michael, pray for me. Amen.
