Thank you for prividing informations!

If you know, do you know why martin luther was divided from catholic church?

Did you read the Wikipedia article on the 95 theses? That's where your answer is.

OK I will read it!

Growing literacy among the people:

Neither of these things happened quickly, but both were long-term effects of Luther's protests and the dawn of the printing press.

Why Did Martin luther, Zwingli and John CAlvin succeed in forming their own churches when others failed?
