Thanks Jon, I’d only change one thing in your post. While Tetzel may have tried to imply that an indulgence could be sold, that error was condemned by the Church, Tetzel being disciplined for that, and some Catholics may have believed they where buying the indugences based on Tetzel’s erronous teachings, they could not, becasue a real indulgence could not be sold.

It would be the same as someone who rented an apartment and tried to sell it as a Condo. He could go through all the motions, even sign papers and take money for the apartment, but it would not be a real estate transaction, but an invalid and illegal contract.
