The “sin no more” line is from the ‘woman taken in adultery’. I haven’t talked about her, but she seems to be Mary Magdalene, whose story is having been possessed by demons.
To a Jewish sensibility, this might be read as ‘intercourse’ with a rival deity . . . especially when the real motivation in attacking her is attacking Jesus. He is the real target.
This story (as usual) is not about sex. There is no mention of Mary ever being married, and thinking of this as ‘adultery’ against an undisclosed spouse- who Jesus semi-forgives or something- seems bizarre.
What Christians trained in churches don’t realize is that ‘sin’ — to a Second Temple Jewish perspective — is the influence of a malign deity. Cue Miryam Brand.
