Could it be that the invention of the Gutenberg printing press and its production of the Bible placed the written Word of God into the hands of ALL normal reading people instead of the priests. All men then had the ability to know the will of God and follow it instead of the directions of men through the church.
That ability lead men to light and out of darkness which is real freedom!
That's an interesting theory. I kind of like it -- the idea of the Gutenberg printing press allowing many Christians to be able to bring in a deeper domestic Church environment into their homes.
Though I will say that Gutenberg didn't create the printing press to separate from Church authority given that he was a devout Catholic who expressed this notion.
Nevertheless, I think that's a great point and for the most part agree with it.
