"Catholic Encyclopedia: Pope Leo X"

“About the Taxa Camarae forgery”

“Give heed to the cause of the holy Roman Church, mother of all churches and teacher of the faith, whom you by the order of God, have consecrated by your blood. Against the Roman Church, you warned, lying teachers are rising, introducing ruinous sects, and drawing upon themselves speedy doom. Their tongues are fire, a restless evil, full of deadly poison. They have bitter zeal, contention in their hearts, and boast and lie against the truth.”

“Made thirty, we should make thirty-one”

“Since God has given us the papacy, let us enjoy it.”

“Leo X to Frederic, Elector of Saxony”

“Arise, O Lord, and judge your own cause. Remember your reproaches to those who are filled with foolishness all through the day. Listen to our prayers, for foxes have arisen seeking to destroy the vineyard whose winepress you alone have trod.”
