This is where we will disagree. I think it obvious from his other teachings that the Golden Rule wasnt all there was of the Law, but simply its over-riding purpose.
We disagree on something I didn't say? Huh?
That, if one loved God and loved others that the law itself would in turn be obeyed. 'Love in that context would mean more than just how we view the word 'love' because in loving God one would obey all his rules and commandments without question as an expression of that love.
Well, okay, I can see where you're coming from.
So, what happens if one's following all the 'rules and commandments' causes one to break the Golden Rule? There's a serious disconnect there, obviously.
[from this point on, 'you' is the impersonal 'you'. Not 'you', the specific person reading the post]
As far as I know, Jesus doesn't deal with it. Luckily, Paul does. He goes into more detail regarding the effects of following the Law. We've dealt with this before.
Galatians 5:22. The Fruit of the Spirit are good things.
If you're following the Law, and it's resulting in breaking the Golden Rule, and NOT resulting in the fruit ... well, it's not the Law. All it is is bad behaviour dressed up in justifications.
Some try to balance the weight of following the Golden Rule & obeying the other rules from God. Neither Paul nor Jesus give equal weight to those two things. Both of them say that it's more important that goodness come from your actions than a strict following of the Law. In other words, if your attempts to follow the law cause a breaking of the Golden Rule, or cause you to not generate the Fruit, you're "Doing it Wrong".
Now, Christians are warned that they'll be persecuted, and some Christians like to throw up their mistreatment as proof of this prophecy. But, if those Christians are being mistreated because they failed to follow the Golden Rule, then this is hardly the persecution they should be glorifying in. Anyone can be a jerk and end up being mistreated. It's hardly a talent or a sign of God's favour.
