vv. 16-17 These are the things that you shall do: Speak the truth to one another, render in your gates judgments that are true and make for peace, do not devise evil in your hearts against one another, and love no false oath; for all these are things that I hate, says the Lord.
Here is a different "summary of the law" than we are used to, a little more elaborated, particularly on the "love your neighbor as yourself" side. In today's passage, God has just said what good he proposes to do to "the remnant." Then, he says, these are the things that you are to do.
It's a good list, one for which most of us can easily sign up. Doing the things on it, however, are quite a different matter. If we used this list as a tool for self-reflection before going to Confession, we would all have plenty to confess. In fact, that might be a good exercise before Christmas (you don't have to call and make an appointment for Confession but it would be perfectly fine if you did!).
How easy it is to get caught up in the world of unjust and unpeaceful judgments, of false promises and unhelpful, if not evil, schemes. God is pretty clear what he thinks about these things: I hate them. What about us?
