In his death, Luther, by the grace of God, destroyed the papacy — even though they yet fail to recognize this today. For centuries, all Christians — even Emperors — had feared the supposed power of the pope, and then a German monk defied the entirety of the papacy, lawfully married a nun, raised Christian children, taught the faith over a course of decades, and died a peaceful, Christian death.
All the fury, rage, and malice of the popes could not bring Luther to an untimely or unnatural death. Instead, he died in his native land, secure in his faith and true in his confession. He left behind a legacy few others in the history of the Church could even approach, let alone match.
