And let's not forget Lucifer. A seemingly eternal being with a great deal of power, at the very least to manipulate. Lucifer is not God. And while he is called a fallen angel, imagine the look on a pagan's face when you tell them stories about Lucifer and then say
UNLIKE YOU WE ONLY HAVE ONE DEITY THAT'S PART OF WHY OUR RELIGION IS SUPERIOR.
Yah, right.
Pagan religions have a variety of entities with a variety of powers and lucifer/satan fits right in the family of trickster/bad gods and godesses.
And if you go to the Protestant churches, say in the Bible Belt, Lucifer/Satan takes on a very powerful role. He is breathing down all of our necks and we are all one step from falling into his clutches. God, on the other hand, is much more transcendant. You have to work to stay in contact with him. With Satan all you have to do is slack off on a Friday night
and he is right there to scoop you up.
Tell me those guys are monotheists.
