And you missed reading my answer, perhaps entirely. The entire basis of the Roman Churh's basis of salvation was a fraud. There WAS nothing left to reform. What was "reformed" was the early and true church of antiquity, the apostolic church described with utter clarity in the Scriptures. When read by elect individuals the truth of salvation in Christ, alone, lept off the pages and ignited a fire not even Rome could extinguish (although they have tried). The Fire, who's origins reached back to the first centuries, once again caused the world to seek not Rome, but Jesus Christ and Him crucified, raised, and ascended to heaven. The truth is now even enticing Rubio and D'Souza.
But, there have always been chosen, real believers rejecting the Roman cult and embracing the truth, little flickers of light in every corner of the dark Roman world. But at the Reformation the return to the truth became a conflagration. Repent, Rome, if you can.
