Luther was wrong then and he is wrong now.
Uh no, the sale of indulgences to replace repentance was what was wrong. Luther will be vindicated on Judgment Day but Catholic leadership not so much. @ 13 months from now will mark 500 years of freedom from the religious monopoly of the RCC. Hail Luther - sent to free mankind and allow the Word of God to flow throughout the world so that all may read the Gospel for themselves. Praise God!
