What Judaism says
Jesus’ teachings are so unrealistic that his disciples themselves don’t even follow them. For example…
Matthew 5:38-40 “You have heard that it was said, ‘Eye for eye, and tooth for tooth. But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. And if anyone wants to sue you and take your shirt, hand over your coat as well.
Jesus was not talking about foregoing self-defense and letting people physically hurt you or your family.
