Remember a few months ago when conservatives in America were banning books due to violence and sexual tones? Yeah someone submitted the bible and it unsurprising got banned due to numerous passages not just having such themes but glorifying them. If any book should not be around children due to sex and violence the bible should absolutely top that list. If you wanted to make a true to source material series on the Bible, getting it rated R would require serious cuts and revisions, and a totally accurate adaption would easily be NC-17
