The point of the video - the bible is as good a source of information on the topic of LOVE, as any ancient desert scribblings. Sure, taken on its own, 1 Cor 13:4-7 is very nice, but not as nice as other descriptions of love that human beings have come up with. And anyway - would you take advice about love from someone whose biography revealed them to be an appallingly UNLOVING character in the first place?
The bible demolishes itself as a useful source for anything, other than an anthropological study in the history of metaphysical wonderings, superstition, ignorance, and delusion. When you read the words on the pages of the bible, what you actually see is horror, fear, violence, anger, rage, jealousy (fuck it, I think jealousy is a pretty low emotion/characteristic), pettiness, death, fear, - the very worst of human nature.
Just because there are a couple of nice sentences scattered throughout it to doesn't make up for the bulk of it being so revolting.
