Now the Lutheran church and Anglican church want full communion with Rome. ??? What? Unless something has drastically changed since I grew up (yeah, it's been quite a while since I attended a Luthern service), the Lutherns do not recognize the Pope as God's voice.
The pope's selling of indulgences was what triggered Luther's action, but his real desire was to bring about change or the end to the corruption which he saw within the papacy itself. But, by attacking the pope as viciously as he did Luther became a heretic instead of a reformer.
