Marketing 101: Create a need, then fill it.
Works with religion, too.
Nothing new under the sun and all is vanity.
Plus:
A man, a child of God, came among the people with a message of Truth.
So, they turn him into a God, and twist the Message, and add all sorts of things to it, tools of fear (what a revelation).
The Sermon on the Mount. The man tells you to find the Father.
At the Nicene Council they destroyed scrolls, eyewitness accounts of this man's life.
They even have the gall to worship the murder weapon.
This evil is sick, and the innocent victims in the trillions over time.
