The specific passages I'd like Luther to explain (no beer for me, thanks) from the viewpoint of his philosophy are listed in my 20, along with reasons why Luther does not understand them.
I would say a man that can not present the gospel is in no position to judge the correctness of the teachings of Luther.
Paul addressed that very thing
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
