I agree you likely offend her with the God comment.
I quickly thought of several stories of my being bad in school since pre k.
You sound like you have been extremely good if this was as bad as you were which still has you upset all these years later.
The teacher calling is actually nice of her. She went out of her way. I got very little of that. Public school during the 70’s mostly. The times my mother got called I was so bad I was getting expelled. She withdrew me instead. I wasn’t punished, just not sent back because it was obvious I didn’t want to be there.
Your parents handled it very well. Why does this still upset you?
