In the “Anne Frank” example, I’d rather trust Jesus to forgive me for lying to protect a person(s) from being killed by a tyrannical State or a criminal.
I also hope and pray that I will be forgiven for the times I’ve told my mother, who is in hospice, that I’m ok and her grandchildren are in good health. She has always been a worrier, and I see it merciful in saving her from other worries.
These are the only two exceptions I have in my rejection of what was called “situational ethics” back in college philosophical discussions in the late 60s.
Good point about lying to your mother in hospice. I agree it is an act of mercy under those circumstances.
Also, I remember reading that a Rabbi said it is permissible to tell a bride she is beautiful even if she is not.
