“Books of apostates, heretics, schismatics, and all other writers defending heresy or schism or in any attacking the foundations of religion, are altogether prohibited.”

Heresy! God gave man a brain and free will, only by allowing him the tool of doubt will he see the truth of God. To ad to this copy and paste from the other Pope; who is God's chief messenger to play God anyway? Read and Write what you wish, what do I care. I agree with Pain and Jefferson fear no truth and Reason is the best weapon against erronius statements.

"As you have the power, sir, to do some service to letters, I implore you not to clip the wings of our writers so closely, nor turn into barndoor fowls those who, allowed a start, might become eagles; reasonable liberty permits the mind to soar--slavery makes it creep." -- Voltaire [A Letter To A First Commissioner]

The pope should censor himself.
