This sterling silver St. Michael medal measures 3/4" in diameter and comes with a 30" black linen cord.
 
Saint Michael the Archangel isn't a saint, but rather he is an angel, and the leader of all angels and of the army of God.  
The title "Archangel" means, that he is above all the others in rank.
St. Michael has four main responsibilities: The first is to combat Satan.
The second is to escort the faithful to heaven at their hour of death.
The third is to be a champion of all Christians, and the Church itself.
And the fourth is to call men from life on Earth to their heavenly judgment.
Very little is known about St Michael other than what is recorded in scriptures.
In Daniel, St. Michael is mentioned as one who helped Daniel, and is mentioned with regard to the end times of the world when he will stand for the "children of thy people."
In the Epistle of St. Jude, St. Michael is said to guard the tombs of Moses and Eve and has contended with Satan over the body of Moses.
In Revelation, St. Michael and his angels, do battle with the dragon.
Today, St. Michel is invoked for protection, especially from lethal enemies.
He is also known as the patron of soldiers, police and doctors.
