If this resembles the poverty of Christ and St. Peter, it is a new sort of resemblance.
This is interconnected throughout the passage "he wears a triple crown, whereas the mightiest kings only wear one crown." The Pope is suppose to be the face of religion but he's so concerned with other things which are not the duties or responsibilities that Christ or St. Peter passed down.
Whenever there is any pretence of fighting the Turks, they send out some commission for collecting money, and often send out indulgences under the same pretext of fighting the Turks.
Church believes that just because the Germans allowed the Pope to claim income from them due to the protection of Christendom from the Turks that its a consist thing. Church is saying just because we want to protect our religion we need your money anytime a presence of fighting is upon us. Finally the Germans had enough later on turning to Lutherism.
After we have gained this, we will create thirty or forty cardinals on one day, and give one St. Michael’s Mount, 2near Bamberg, and likewise the see of Wurzburg, to which belong some rich benefices, until the churches and the cities are desolated; and then we shall say, We are the vicars of Christ, the shepherds of Christ’s flocks; those mad, drunken Germans must submit to it.
His frustration here is related to the power that Catholics were trying to gain by appointing all the cardinals. It costs excessive amounts of money to do this which created pressure on the people and took the focus away from religion. Luther felt this was unnecessary.
