Well, I do not know nothing about Catholic part of Europe, but there was a man named Martin Luther who lived between 1483 and 1546. The whole point (or cover story at least) of European protestant movement (in contrast to the English one) was to make the word of God accessible to the people (i.e. remove the Church monopoly of scripture reading).

Printing press was already invented in 1440 to print all the bibles necessary.
