Yes, they do believe that. They believe that before Satan was cast out of heaven, Jesus was once named Michael and that he was the one who expelled the Devil from heaven. (Revelation 12:9-12)
There are many saints named Michael so you need to be specific.
There could be other saints named Michael, but THE Saint Michael is not a person, but an angel, so he didn't have a "life." His principle deed was defeating Satan and casting him out of heaven.
Michael the Archangel drove Satan and his followers out of Heaven.
He drove Satan and his fallen angels out of Heaven.
The Angel Michael has never been thrown out of heaven. You might be thinking of the angel Lucifer (Satan).
Saint Michael the Archangel is the leader of God's Army and was responsible for removing Satan and his rebelious followers from Heaven.
the devil himself was an arch angel until he challenged God because he wanted to have heaven as his own.Satan gathered other angels in heaven who felt the same as he did and challenged God to battle for heaven. God sent saint Michael and the rest of heavens angels to battle Satan and his "angels".saint Michael won the battle and drove Satan out of heaven and Satan fell down to hell along with all the "angels" that challenged God.
The archangel Michael has cast Satan from heaven down to the earth. Revelation 20:1-3 says an angel in heaven has a key to the abyss where Satan is held for 1,000 years. The resurrected Jesus seated at the right hand of God can be identified with these events.
Saint Michael never lived. He is an archangel, meaning that he lives in Heaven and kicks Satan out if he ever gets close.
Michael had a war with with an evil power.He was the war cry of the good angels in the battle fought in heaven against Satan and his followers.
Satan said farewell to Heaven when he challenged God.
