The Bible describes God showing Moses his 'backside', which a number of actual scholars interpret as including his butt.
Not sure about farts in the Bible, but there's stories about rape, incest, at one point a description of men with 'emission like donkeys', ie, huge cum loads from big dicks.
They seem to never learn that if you try to ban 'pornographic' text, you'll have to ban the Bible as well.
