I just thought that a movie that includes a reference to Lot and to father-daughter incest ought to at least reference the Bible quote about exactly that.
Whether it's paintings, poems, movies, stories, or sermons, they always leave this part out.
Bible-quoters who use the thing to justify themselves have it down to a fine art, quoting the bits that make them seem validated and avoiding the bits that are inconvenient to them.
But the Bible isn't even close to being thematically consistent; it's a hodge-podge. The first half of the Old Testament was written for and among desert nomads, and is mostly about trying to survive in a harsh environment, which dictates everything from the food they do or do not eat and the clothes they wear and how they wear them, to rules of behaviour meant to keep a bloodline viable. Their god was a god of war -- jealous, territorial, vindictive and quick to anger -- who unsurprisingly talked a lot about smiting their enemies and demanding obsessive, almost genocidal obedience.
That we spin high-faluting moral tenets out of their struggle not to be obliterated, and turn those into rules for being "good", is farcical at best.
You might very well think that. I couldn't possibly comment.
