And all those princes wanted to be free of the restrictions the Church set on their power and Luther gave them the opening.
If the princes wanted to be free of the control of the church that demonstrates that the church sought control of the princes. The church established orthodoxy or legitimacy and if the church denied them legitimacy they could use Luther to do away with that practice or they could submit to the idea that the church was the source of legitimate authority.
Thomas Jefferson moved the prerogative to resist that power to confer legitimacy one step further to the people.
Who can blame them in light of th4e abuse of power the Catholic church was engaged in at the time?
Where did Jesus ever establish the church to be a dictatorial governing body over ALL men wielding political power?
