Michael the Archangel
And war broke out in heaven.
Michael and his angels fought with the dragon;
and the dragon and his angels fought,
but they did not prevail,
nor was a place found for them in heaven any longer.
So the great dragon was cast out,
that serpent of old, called the Devil and Satan,
who deceives the whole world;
he was cast to the earth,
and his angels were cast out with him.
(Revelation 12; 7-12)
