In Judaism unlike Christianity belief in original sin does not exist.I think the notion original sin is one of the most damaging aspects of Christianity,It was promulgated by St Augustine of Hippo on the grounds that a baby had touched a vagina and therefore was tainted.. this shows the Christian view on women and sexuality,Men would be tainted.This may explain celibacy and child abuse.Presumably touching a penis or anus was not as sinful as touching a vagina or breast.
Pushing this idea on the laity created fear/terror of mortal sin and hell.That’s another new creation that did not exist as far as I know in Judaism.Fear of sin can be used to control people.The priests had too much power but now we are more inclined to make up our own minds since the row over whether contraception is ever permissible.The Pope said it was wrong and few people were willing to obey.

So it seems I am mistaken in thinking it’s a Christian invention.I can see it amkes sense to label the first sin of Adam and Eve as the original sin.Thank you for letting me know.I always disliked te notion of original sin but wity=h the way the world…is now it seems like we do have a tendency to evil.Who knows what we’d do if if under duress.The people who are truly good may be killed like Dietrich Bonhoeffer for example.Where do they get their strength,I wonder/
Thoughtful post. Shame and blame are all too powerful weapons in the hands/minds of the unscrupulous. Next step it’s the Spanish Inquisition or equivalent. Hair-raising, and so unholy.
