“That the Roman church has never erred; nor will it err to all eternity, the Scripture bearing witness.”

“That he alone may use the imperial insignia.”

“It is the custom of the Roman Church which I unworthily serve with the help of God, to tolerate some things, to turn a blind eye to others...”

“I have loved justice and hated iniquity; therefore I die in exile.”

“Cursed be the man who holds back his sword from blood.”

“That the Roman pontiff alone can with right be called universal.”

“That it may be permitted to him to depose emperors.”

“That he himself may be judged by no one.”

“Who does not know that kings and rulers took their beginning from those who, being ignorant of God, put themselves above their fellows by pride, plunder, treachery, and murder...”

“Let the kings of the earth and all their princes know and fear, how great you are, and that there is no God but you.”

“We desire to show to the world with a clear demonstration that it is not by our own presumption that we have entered upon this contest, but that we are defending the cause of God and of our mother the church.”

“For to me it is a token of the greatest love to tell a man the things that are for his own salvation.”

“If any one shall have received a bishopric or an abbacy from the hand of any lay person, let him not be regarded as a bishop or abbot.”
