"I have said over and over again that I have used McGrath to show that Luther's interpretation is novel and that gives a reason to reject the Protestant's view on justification."
Note the double standard. When the same historical standard is applied to certain Roman Catholic dogmas, like Mary’s Bodily Assumption, Purgatory, Indulgences, etc., this same historical standard is swept under the rug and hidden. One has to seriously question why a standard that Catholic apologists hold Protestants to is not likewise applied to their own beliefs. Wade through the corridors of church history and search for the threads of all Roman Catholic dogma. One falls flat of linking many of them back to the early church, or in some instances, even the Bible.
