Protestants around the world today celebrate their distinction from the Roman Catholic Church proudly and regularly. Yet, how many actually know the history behind their separation? The old adage "you can't know where you are going until you know from where you came" may not ring true in every situation, but the sorrowful state of biblical orthodoxy in Protestant churches today demonstrates the value of this old proverb.
