AH.com theology crew shows up for this-
were Lutheranism and Calvinism particularly distinct in terms of the depth and maturity of theology compared to prior movements such as the Hussites and the Lollards and the Waldensians and what have you?
The biggest difference was that the printing press was already there, so Lutheran ideas spread much more quickly.
Theologically, they were distinct from the previous movements - consider e.g. the Three or Five Solae, which weren`t there in the earlier reformation -, but not necessarily by depth and maturity in theology. One could say that Luther and Zwingli were really shallow in comparison to the theological discourse that preceded them, just think of Cusanus` complex, philosophically deep and politically relevant theology.
Lutheranism is pretty plain, and it is decidedly politically bland, in comparison to all the aforementioned movements. Maybe that was the key to its success: it was not such a socially dangerous tool to latch on to for the rebellious princes and the autonomy-seeking city states.
