Welcome to Gaia! ::

Even within organized christianity, there are several different views on Satan as a being: The Tempter, The Punisher, The Rebel, The Lawbreaker(of God's law) and The Most Abhorrent Being in existence. However, in practice, Satan actually mostly seem to fulfil the role of The Scapegoat, always getting blamed for EVERYTHING BAD.

Due to this, I have concluded that "Satan" do not exist as such, it is merely a literal strawman that is filled with whatever abnormalties that one consider to be unforgiveable, to be attacked and killed or burnt to ashes for the sake of maintaining one's own "purity".

...And as for Satan being able to convince the world that "he" does not exist, I just say that that is not a power that Satan has, that is the power that GOD has.

As for "pushing narratives" .....
* finally reads the link, or parts of it *
...my God, I am not surprised that the name "Satan" proves to be yet another case of "One People's God is another People's Satan or Devil".
It is the same throughout history ....
I'm not sure if the author of that article goes too far or not, though.

......but jeezzzz, are the comments afterwards occasionally flame material, so best to avoid those.
