They say unto him, Rabbi, this woman was taken in adultery, in the very act. Now Moses in the law commanded us, that such should be stoned: but what sayest thou? This they said, tempting him, … they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
In other words, unless completely perfect, one is imperfect. This is a different sort of measure than is used in assigning blame in a car crash, or in torts.
Those would take the total sum of damage and fractionally assign responsibility to each party. Allow me the licence to define the “Jesus norm” as above.
It would say that one is either responsible or not responsible.
So if I hurt you at all, I’m equally as responsible as everybody else who hurt you for making you whole again.
