“You have heard that it was said, ‘Eye for eye, and tooth for tooth.’[a] 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. If anyone forces you to go one mile, go with them two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you.
One of the problems Jesus followers have is Jesus’s fulfillment of the Old Testament. It’s not really a problem in itself, but it should end up impacting how we read the Old Testament, indeed how we read the entire Bible. If Jesus conquers in the way portrayed in the Old Testament, blasting his enemies, then that holds good today. We can justify such actions, and even try to Christianize them, put the name of Jesus somehow on them. But if Jesus’s way is the way of the cross involving loving our enemies, praying for them, and doing good to them, then we realize it just doesn’t work to engage in what is called a flat reading of the text, that is to think we can literally apply the Old Testament just the way it’s read. If Jesus didn’t, then as followers of Jesus, we shouldn’t do so either.
