The Archangel Michael, whose name means 'who is as God', is generally considered to be the foremost of the seven archangels and the leader of the Host of Heaven. He derives originally from the Chaldeans by who he was worshiped as something of a god. He is the chief of the order of virtues, Prince of the presence, angel of repentance, righteousness, mercy and sanctification: also ruler of the 4th Heaven, tutelary sar (angelic prince). He is the prince who defended the Israelites and later, it was claimed, the Christian Church, when as guardian he may be called on (sometimes with Gabriel) to defend church doors against the evil angels. According to the Book of Revelations, Michael and his angels' are described as fighting the dragon and his angels. Hence, Michael is often shown fighting or overcoming a dragon armed with spear or sword as God's Warrior.
