Thanks for the Justin quotes, Paidion!
Have you read Michael L. Brown before, Neil? He’s a Jewish Christian author, and I like (some of) his work a lot (though he isn’t universalistic. Yet. 
)
Two relatively brief synopses of his Jewish/Christian work can be found here and here (on Amazon).
Those summarize and somewhat repackage his giant 10-year five-volume work on Jewish objections to Jesus starting here.

Scripture informs us as to the significance of the Law of Moses for those who believe in Christ: *Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. But after that faith is come, we are no longer under a schoolmaster. For ye are all the children of God by faith in Christ Jesus. *Galatians 3: 24-26. The Law of Moses teaches us that we are all unworthy to come into the presence of God without justification through the sacrifice of Jesus Christ for our sins. The Law of Moses, and all of Holy Scripture brings us to the knowledge of salvation through Christ.
The truth of what is written in Scripture is confirmed by a method of gematria which I have used and have explained in an attachment to my post on the thread "How should we treat and approach the Bible? In order to make the attachment to this post meaningful, one should read the attachment on that prior post. I realize that gematria is looked upon with great skepticism, especially with the unusual method which I have used, but the findings are quite remarkable.

I also agree with Cindy’s take on it. To the multitude (all versions of Messianic, Hebrew roots, Reformed Covenant Theologians, not to mention just about every evangelical pastor on the planet, and your everyday Christians) who have developed ingenious methods of “cherry picking” from the Law of Moses, I have one thing to say. You have only two choices, take the whole enchilada or accept the fact that in Christ you have died to the Law and are now joined to another suitor, the Lord Jesus Christ. Didn’t Jesus said that not one jot or tittle would be removed from the Law until all was fulfilled? Didn’t James write, “Whoever keeps the Law but fails in one point is guilty of all of it”? James 2:10 . The law was the covenant that God made with the nation of Israel. It had different aspects moral, civil, ceremonial, but it must stand or fall as one document. Read Paul’s argument in 2 Cor. chapter 3 or the whole book of Galatians or Hebrews and then make your argument.
Wasn’t Jesus talking about the prophecies concerning Himself that are found in the OT books known as “the law”? He said that Moses wrote about Him.
Gentiles were never under the Mosaic law, period. That was a Jewish thing entirely. And when Paul speaks of the law, that’s what he’s talking about. So sayeth NT Wright and others, in any case.
That’s exactly right Dave.
Just for consistency though I’d love to get a handle on Wright’s response then to such reactive retorts as… “oh, so none of it applies to us and hasn’t for the past 2000yrs!?” 
Are you saying you believe that the inspired portions of the law that pertained to Christ were “hidden” among the vain imaginings of this ancient people? I’m not accusing, only seeking clarification.
According to Jews, all Jews and Gentiles are to abide by the Noahide commandments. Which are:
And of course Jews are bound by ~ 613 more from Moses.
The Noahide commandments seem pretty fair to me though.
I think in the LOM there are moral laws which are eternal and ritual laws which were for Israel. IMO the Sabbath is a ritual law even though it is part of the 10 Commandments and as Hebrews says our rest is in Christ not any particular day.
Yes, and yet many/most Christians willingly put themselves under the curse of the law to some extent, because of their ongoing misunderstanding of the true nature of God, and of the need to divide the Scriptures by the Spirit, and not the letter.
I would argue that legalism—trying to serve God in the flesh instead of by the Spirit—began in mankind after eating from the Tree of the Knowledge of Good and Evil. So it is a bigger problem, a universal problem that has always reigned far beyond the eventual codified Law of Moses to the Israelites.
Legalism is very bewitching, and Paul tried to reason with the Galatian Christians (both Jews and gentiles) about it:
Galatians 3:1-3,10,13
1 You foolish Galatians! Who has bewitched you? Before your very eyes Jesus Christ was clearly portrayed as crucified.
2 I would like to learn just one thing from you: Did you receive the Spirit by the works of the law, or by believing what you heard?
3 Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the FLESH?
10 For all who rely on the works of the law are under a curse, as it is written: “Cursed is everyone who does not continue to do everything written in the Book of the Law.” [Deut. 27:26]
13 Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: “Cursed is everyone who is hung on a pole.” [Deut. 21:23]
(I believe legalism and its attendant curses are from the devil, not from our unchanging, gracious God of love.)
Right on, Dave. We are under no obligation to be under any aspect of the law, including the 10 commandments, especially the Sabbath.
Jesus Broke the Sabbath
John 5:18 Therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath, but also said that God was His Father, making Himself equal with God.
Justin Martyr’s Explanation of the Sabbath to the Jews in his "Dialogue With Trypho"
(Justin was a Christian who lived from (A.D.110 – 165)
Righteous Men of Old Kept No Sabbaths
… all those righteous men already mentioned [Abel, Enoch, Noah,] though they kept no Sabbaths, were pleasing to God; and after them Abraham with all his descendants until Moses… Chapter 19
…For if there was no need of circumcision before Abraham, or of the observance of Sabbaths, of feasts and sacrifices, before Moses; no more need is there of them now,…Chapter 23
Nature Does Not Observe Sabbath Days
Do you see that the elements are not idle, and keep no Sabbaths? Chapter 23
God Himself Does Not Observe the Sabbath Day
Think it not strange that we drink hot water on the Sabbaths, since God directs the government of the universe on this day equally as on all others… Chapter 29
The True Israelites Are Those Who Come to God Through Christ
For the true spiritual Israel, and descendants of Judah, Jacob, Isaac, and Abraham (who in uncircumcision was approved of and blessed by God on account of his faith, and called the father of many nations), are we who have been led to God through this crucified Christ, as shall be demonstrated while we proceed. Chapter 11 (near the end)
We Are Now Required To Keep Sabbath Daily By Resting From Sin and Working Righteousness
The new law requires you to keep perpetual sabbath, and you, because you are idle for one day, suppose you are pious, not discerning why this has been commanded you: and if you eat unleavened bread, you say the will of God has been fulfilled. The Lord our God does not take pleasure in such observances: if there is any perjured person or a thief among you, let him cease to be so; if any adulterer, let him repent; then he has kept the sweet and true sabbaths of God. If any one has impure hands, let him wash and be pure. Chapter 12 (at the end)
