Was Luther right to protest about the heresy of the Roman Church

Hi urbandekay, Forgive me if I say anything inaccurate or incorrect, I'm just speaking from personal understanding picked up here and there over many years... I believe Luther was right to point out the errors of the human heirarchy of the Church that he could see. Simple justice demands that. But his solution, by expounding the philosophy of self-determination, was actually a gift to anyone who wanted to undermine God's Church on earth. "Divide & conquer", we might say. From what I've read, Luther himself lamented his error (the idea that each person determines their own moral code without need for deference to an external authority) on his deathbed. I agree the Catholic Church has always been subject to the corruption of human weakness and bureacracy, but that's an unfortunate risk of having God's institution staffed with human caretakers. It is God's institution nonetheless. I guess a compelling contrast to Luther's approach to corruption in the Church was that of Saint Francis of Assissi, a holy fellow who lived a life of poverty, and who the Church heirarchy was determined to excommunicate for daring to challenge their views. Saint Francis traveled a long distance by foot to Rome where he persuaded the Pope himself to change Church policies on various things. Of course, Saint Francis was a man of God, and was known to float around the tree tops and church steeples when deep in prayer, and was inspired to go talk to the Pope by God Himself. Which gets back to the point that the Church may get stuffed up periodically by its heirarchy of human caretakers, but it's God who ultimately calls the shots. I think Luther was a good man, and well intentioned, but what he started has snowballed over the centuries to cause great damage to the unity of God's Church and His people on earth.
