To repeat, this simply doesn't sound like the reformers, who were all considerably educated men. All of them would affirm the biblical principle of study. These few I've pulled out are indicative of heartburn I have with a lot on the above list. I consider them caricatures (at very best) of what I believe.
To all three: Fair enough. In fact, I have often been astonished by how convoluted and filtered through complex rules of hermeneutics the Protestant reading of the Bible is.
The rhetoric of Bible perspicuity still makes rounds in some circles though, does it not? At least historically that was a major part of Luther's theological revolution.
