What I was saying, is that the Law is one thing, and love is another.
I already presented an argument to the effect that love is a summation of the law and, as such, it makes no sense to see them as separate or to think you can be loving while acting contrary to the law (murder doesn't seem like a loving thing to do to me). I haven't seen your response to that (although maybe I posted that argument in a different thread).
What you are not realizing is that even though love your neighbor as yourself might fulfill the Law, it will not fulfill the new commandment of Jesus, which is to love one another even as He has loved us.
I don't buy the idea that these two laws are opposed to one another or that they are fundamentally different. Jesus provided the example of what true love looks like. The command in Leviticus wasn't intended to express a lower form of love, it just didn't have the perfect example of Jesus.
We, as Gentiles, were never a part of the covenant of which the Law is a part, and so we were never under the Law, because we were excluded by birth. But we have been made one with those people, the nation of Israel, by Jesus, that is, by His death, in which He removed the barrier between us and them, which was the Law.
If one follows the Law, they have no part in Christ.
As I read through the law I get the impression that the law is a reflection of God's moral character. As such, it isn't subjective in the sense that it is good for one group of persons to commit adultery but bad for others (or that homosexuals deserve death in some societies but not in others, but that opens a whole different can of worms and I'm not say that we, in America, should put them to death). God has one standard of morality and that standard applies to all persons.
Le 24:16 Whoever blasphemes the name of the LORD shall surely be put to death. All the congregation shall stone him. The sojourner as well as the native, when he blasphemes the Name, shall be put to death.
Le 24:22 You shall have the same rule for the sojourner and for the native, for I am the LORD your God.
Ex 12:49 There shall be one law for the native and for the stranger who sojourns among you.
Nu 15:15–16 For the assembly, there shall be one statute for you and for the stranger who sojourns with you, a statute forever throughout your generations. You and the sojourner shall be alike before the LORD. 16 One law and one rule shall be for you and for the stranger who sojourns with you.”
Nu 15:29 You shall have one law for him who does anything unintentionally, for him who is native among the people of Israel and for the stranger who sojourns among them.
Dt 4:5–6 See, I have taught you statutes and rules, as the LORD my God commanded me, that you should do them in the land that you are entering to take possession of it. 6 Keep them and do them, for that will be your wisdom and your understanding in the sight of the peoples, who, when they hear all these statutes, will say, ‘Surely this great nation is a wise and understanding people.’
Dt 5:12–14 ‎“‘Observe the Sabbath day, to keep it holy, as the LORD your God commanded you. 13 Six days you shall labor and do all your work, 14 but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, you or your son or your daughter or your male servant or your female servant, or your ox or your donkey or any of your livestock, or the sojourner who is within your gates, that your male servant and your female servant may rest as well as you.
It seems clear to me from these verses that God didn't just hold the Israelites to his moral standard. He did, however, enter into a unique covenant with them which made them especially responsible for his law: to whom much is given, much is required. The fact that we don't see Israelites putting a person to death who lives in another country is only because Israel didn't have jurisdiction over those other countries. It would be like saying that because America can't prosecute French people who illegally immigrate to England that therefore it must not be wrong for French people to illegally immigrate to England. Whenever it was possible, the authorities were to hold Jew and Gentile under the same law, because the same law applies to all.
