At the First Diet of Speyer, every member of the Empire is
instructed in how they should respond to the Edict of Worms, being
told that their conduct in relation to this injunction must be able
to answer to God and his Imperial Majesty. However, the subsequent
disagreement between Charles V and the Pope prevents him from
enforcing the Edict.
