OK, well...first I've heard this version. Shows there's scholarship to prove just about anything I suppose. I will say that what the writer wrote doesn't wholly dismiss the story, just the unlikelihood, noting Luther didn't want to provoke his superiors. I suspect at that point in time, provoking his superiors was precisely what he had in mind...it would have been mine. And yes, he sided with the nobles...that's what kept him alive and out of reach of the Pope's minions, who were on the hunt and ready to grab Luther and drag him back to the Vatican, pretty much "dead or alive." After the 95 theses (nailed or not), Luther had a bounty on his head and was no longer safe to preside over the local church. He was allowed refuge in the castle of an influential nobleman who sheltered him and allowed him to continue his studies. As I recall this nobleman was the same man who brokered the meeting with the Vatican officials for a debate...which Luther won handily. All of this was sensational news at the time, printed out and distributed to a wide audience much like we have tabloid news now, but all that was very novel and new at the time. In a way, Luther was the rock star of his day.
