Shame and Guilt – where it comes from

I have a friend who swears that the program of shame and guilt comes from the Christian religion. Being Christian myself, I disagree with her, but can see how she would assume that based on what beliefs her parents passed down to her. I started to explain to her that our brains have a software program running called, “Something is wrong with me,” and that it is the primal brain’s way of protecting us.

I understand the need for the primal brain to protect us, but I would like more clarification on the emotions specifically of shame and guilt. I’m trying to get it from the podcasts, but would like to dial in my understanding even further.

Thank you!
