If you read in the Chiesa Viva I posted, one of the tactics of the Freemasons was to do this:
15. Make the images of angels disappear. Why to hold between the feet the depictions of our enemies? Define them as myths or stories for a good night.
16. REPEALED (the authority of) The Exorcist to eject MINOR demons. Engage in this, even stating that the Devils do not exist, explain that it is only a literary device to define evil, because, without an opponent, the stories are not interesting. Consequently, people stop believing in hell, or deem that they, themselves, will never fall. Moreover, repeating them is more of the distance from God, believing that if there is a species of life on earth like that.
