Martin Luther,
Concerning Christian Liberty; with Letter of Martin Luther to Pope Leo X
“ Therefore, Leo, my Father, beware of listening to those sirens who make you out to be not simply a man, but partly a god, so that you can command and require whatever you will. It will not happen so, nor will you prevail. You are the servant of servants, and more than any other man, in a most pitiable and perilous position. Let not those men deceive you who pretend that you are lord of the world; who will not allow any one to be a Christian without your authority; who babble of your having power over heaven, hell, and purgatory. ”
