The two different versions of the 10 commandments are actually just essentially summaries of the "book of the covenant" which are the 613 different commandments. So that constitutes "the law". And then there are teachings of the prophets, and so the "law and the prophets" is all of it as a whole. What I strongly feel that Jesus was instructing was that getting hung up on the "letter of the law", misses the "spirit of the law", or the basic intent. It's to get us to look at the attitudes of the heart, the "inside of the cup", as opposed to focusing on the externals. This is what differentiates the "new covenant" from the "old covenant".
So when you have those worrying about did I do the 4th commandment right, or the 36th commandment, or the 421st commandment correctly, they are focusing in the wrong place. It's really not about not mixing two types of cloth that God actually cares about. But to the legalist, they imagine that is what matters.
I have come to realize through this discussion that the entire difference in understanding boils down to the nature of how we understand what love is. Those that are legalists see love as something earned or deserved. You have to obey God, for God to give his love to you and accept you. To those under Grace, they see love as unconditional. Which does not mean lawlessness in the least. It means that one follows the ways of God, because they experience that Love from God through Grace, undeserved, unearned. It is through humility that they are raised, and when raised, they act from a place of love in their hearts. And from that place of love inside that cup, the entire spirit or intent of the law and prophets is fulfilled, namely to Love: God and Others, though the Love that comes from God, to them, and through them, to the world.
This is the dividing line. This is the watershed point, where entire different understandings of the nature of God and ourselves and the world, and our interpretations of scripture part ways. One goes to the west coast, the other to the east coast to different oceans. The legalist hears unconditional love as lawlessness and a lack of discipline, or God sparing the belt. That is how it is presented in discussions, again and again in this thread. That betrays a lack of experience of what it is, and the only thing that can be related to is a parent who doesn't beat their children to get them to obey them and deserve their love which is conditional upon living up to that parents expectations.
It is truly like the Matrix. You cannot be told what unconditional love is. You have to experience it for yourself to know what it is.
I think this cartoon perfectly captures this contrast I am pointing out here:

I tend to agree with what you said but unfortunately most of it is probably not the sort of thing that is going to convince @3rdAngel,,,,,,,,,,,, if there even is such anything that will convince him. He has done his homework and studied the scriptures with the help of God it seems (and probably with the help of literature from a 7th day Sabbath group also) and he does not seem to realise or want to admit any errors we can point out to him or any inconsistencies or assumptions. We see assumptions that "Commands of God" must mean "the 10 Commandments" and he does not see that.
