Confusedly or Confusingly

I've just been reading an excerpt from Rowan Williams on Maurice Wiles at Michael Jensen's blogging parson.

MJ tells us to note that Williams says doctrine (or something) is ofetn very variously and very confusedly articulated in our primary documents (such as Scripture).

The word I am duly noting here is confusedly.

Note that it is not confusingly (which would tell us about Williams: that the Bible confuses him) but confusedly (which tells us about the authors, human and divine ?, that they were confused).

Williams may be able to hold on to some sort of idea of the authority of the Bible, but he has lost its perspicuity or clarity, so for my money for all practical purposes he has given up on the functional authority of Scripture.

What is his practical substitute, I wonder?

Maybe the Revd Mr Jensen can enlighten us?

I doubt Williams can.
