Actually, we've established a few things.
We've already acknowledged that God's timing was ideal. The Reformation came at the time that the printing press showed up.
Second, this article is evidence of GREAT, EVIL CORRUPTION of that period. That corruption made the Reformation not just necessary, but also Godly.
Or did it come about because the printing press showed up?
Not only because the printing press made mass-produced Bibles possible, but perhaps more because it made mass-produced propaganda -- in the form of leaflets, tracts, posters, etc. -- possible.
The article is a pack of lies.
