For those too lazy to look it up themselves, here's the Wikipedia page on it:
http://en.wikipedia.org/wiki/Wesleyan_QuadrilateralNow, as to my opinion, based on the wiki's description it's just the usual nonsense:
The shape isn't one in which all of the items are equal, the shape is one in which the scriptures take precedent above all else. If something is in contradiction with scriptures, it's wrong. That's the basis of the whole thing. You don't use reason to see that the scriptures are true, you assume they are true to begin with, and as such you might as well throw reason out the window.
