Bishops should despise this world and inspire others by their example to seek after heavenly things. But now you are corrupted by ambition beyond all the rest of mankind; and one of them not content with holding the first episcopal see in Germany has dared without my approval to claim my golden sceptre, which I carry to signify my royal will, in order that he might use it as his pastoral staff.
