Whether Luther was this or that really is of no importance. He was inevitable though, had it not been him it would have been someone else.
The printing press would soon make Bibles and books widely available and the reader could judge the failure of the Catholic church for themselves and whether Luther’s reforms represented true reform or simply a shift in power.
That’s true. Luther is just a convenient scapegoat. Someone for the RC’s to direct their hate towards. Unless he’s being their hero for some reason or other.
