One more edit: Paul actually agrees with James when says something like "if I have all the faith to move mountains, but no love..."
Not only that, but he also specifies that he is speaking especially of the works of the law, if I am not mistaken.
Nevertheless, I do believe there is a deeper meaning, and I'll reference the Holy Prophet Elijah: "For all of our righteousness is as filthy rags".
I suggest that we address this directly to the source of our salvation, Jesus Christ: "He committed no sin, and no deceit was found in his mouth." Yet if he wasn't saved according to the Mosaic Law (which is not to suggest that he transgressed it), according to what law then was he saved? Is it even proper to suggest that he was somehow "saved" from something, who "committed no sin, and no decit was found in his mouth"?
