Michael is an archangel in the religions of Judaism, Christianity, and Islam. To Catholics, Eastern Orthodox Christians, Anglicans, and Lutherans he is called "Saint Michael the Archangel and Saint Michael". In other Protestant churches, he is referred to as Archangel Michael. The name Michael means 'who is like God?'., he is described as the protector of Israel and leader of the armies of God against Satan. Michael is perhaps best known for his victory over the dragon, which is told in the Revelation to John.
"And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, and prevailed not; neither was their place found any more in heaven" (Rev. 12:7).
As recounted by the Revelation of Saint John, at the end of the world war will break at between Heaven and Hell, between good and evil. As the commander of the Army of God, Archangel Michael leads the other angels in the fight against evil, represented in this picture by a seven-headed dragon. Each of the dragon's heads represents one of the seven deadly sins.
Michael is therefore regarded as the protector of Christians from the devil, particularly those at the hour of death. Sanctuaries to Michael were built by Christians in the 4th century, when he was first seen as a healing angel.
