This is foolishness. Just because Luther did evolve his beliefs gradually, does not imply anything about the corrupt Roman Church, then and now, being anything close to right. The fact that they impose dogmatic and non-biblical ideas such as the Assumption of Mary, the Immaculate Conception of Mary, Indulgence at all, Purgatory at all, etc, indicate that they wrong. That Luther realised this gradually is indication that he is human. Simple.
