You don't know what you're talking about. The passages you quoted from Luke and Hebrews are the fulfillment of Jeremiah's prophecy. The only difference between the old covenant and the new is that the former was written in stone and the latter was written in the hearts (minds) of those who live by Jesus' example.
Quoting from the ISR:
“And יהושע said to him, ‘You shall love יהוה your Elohim with all your heart, and with all your being, and with all your mind.’ This is the first and great command. And the second is like it, ‘You shall love your neighbour as yourself.’ On these two commands hang all the Torah and the Prophets.” Matthew 22:37-40
Loving God with all heart, being, and mind requires keeping His commandments.
“And He said to him, “Why do you call Me good? No one is good except One – Elohim. But if you wish to enter into life, guard the commands.” Matthew 19:17
“If you love Me, you shall guard My commands.” John 14:15
“יהושע answered him, “If anyone loves Me, he shall guard My Word. And My Father shall love him, and We shall come to him and make Our stay with him. “He who does not love Me does not guard My Words. And the Word which you hear is not Mine but of the Father Who sent Me.” John 14:23-24
“And by this we know that we know Him, if we guard His commands. The one who says, “I know Him,” and does not guard His commands, is a liar, and the truth is not in him. But whoever guards His Word, truly the love of Elohim has been perfected in him. By this we know that we are in Him.” 1 John 2:3-5
“Blessed are those doing His commands, so that the authority shall be theirs unto the tree of life, and to enter through the gates into the city.” Revelation 22:14
Pay attention:
“Do not think that I came to destroy the Torah or the Prophets. I did not come to destroy but to complete. “For truly, I say to you, till the heaven and the earth pass away, one jot or one tittle shall by no means pass from the Torah till all be done.” Matthew 5:17-18
Have heaven and earth passed away yet?
"Whoever, then, breaks one of the least of these commands, and teaches men so, shall be called least in the reign of the heavens; but whoever does and teaches them, he shall be called great in the reign of the heavens" Matthew 5:19
Oops!
And יהושע said to him, ‘You shall love יהוה your Elohim with all your heart, and with all your being, and with all your mind.’ This is the first and great command. And the second is like it, ‘You shall love your neighbour as yourself.’ On these two commands hang all the Torah and the Prophets.” Matthew 22:37-40
Here Jesus is not requiring the 661 laws of the Torah but all those laws can be kept in these two above.
At the council of Jerusalem, Barnabus and Paul plus the elders of the church at that time met about the issue of circumcision and Mosaic law. With the universal Christian message that it is not by the law (works) that we are saved but by grace (Acts 15:1-29)
7 After much discussion, Peter got up and addressed them: “Brothers, you know that some time ago God made a choice among you that the Gentiles might hear from my lips the message of the gospel and believe. 8 God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us. 9
He did not discriminate between us and them, for he purified their hearts
by faith. 10 Now then, why do you try to test God by putting on the necks of Gentiles a yoke that neither we nor our ancestors have been able to bear? 11 No!
We believe it is through the grace of our Lord Jesus that we are saved, just as they are.”
Acts 1:7=11
James agrees Gentiles are to be included with Jews and quotes scripture in verses 13-18
13 When they finished, James has described to us how God first intervened to choose a people for his name from the Gentiles. 15 The words of the prophets are in agreement with this, as it is written:
16 “‘After this I will return
and rebuild David’s fallen tent.
Its ruins I will rebuild,
and I will restore it,
17 that the rest of mankind may seek the Lord,
even all the Gentiles who bear my name,
says the Lord, who does these things
18 things known from long ago.
Once the decision was made by the counsel to drop Mosaic law for the gentiles, a letter was sent to the Gentile believers in Antioch, Syria, and Cilicia:
Verses 27-29
27 Therefore we are sending Judas and Silas to confirm by word of mouth what we are writing. 28 It seemed good to the Holy Spirit and to us
not to burden you with anything beyond the following requirements: 29 You are to abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. You will do well to avoid these things.
Mosaic law was no longer required for gentiles. Jews still kept it. Gentile Christianity is what spread through the Empire, then Europe,Asia and the rest of the world. I'm Not familiar with Messianic Christianity. I don't know if it has always been there since ancient times or if it is new so I can't comment on Jewish Christianity.
For if those who are of the Law are heirs, faith is made void and the promise is nullified; for the Law brings about wrath, but where there is no law, there also is no violation. (Romans 4:14-15)
For the Law, since it has only a shadow of the good things to come and not the very form of things, can never, by the same sacrifices which they offer continually year by year, make perfect those who draw near. (Hebrews 10:1)
But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things, to which you desire to be enslaved all over again? (Galatians 4:9)
For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh, so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit. (Romans 8:3-4)
When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear. (Hebrews 8:13)
For, on the one hand, there is a setting aside of a former commandment because of its weakness and uselessness (for the Law made nothing perfect), and on the other hand there is a bringing in of a better hope, through which we draw near to God. (Hebrews 7:18-19)
Not that we are adequate in ourselves to consider anything as coming from ourselves, but our adequacy is from God, who also made us adequate as servants of a new covenant,
not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. But if the ministry of death, in letters engraved on stones, came with glory, so that the sons of Israel could not look intently at the face of Moses because of the glory of his face, fading as it was, how will the ministry of the Spirit fail to be even more with glory? (2 Corinthians 3:5-8)
For Christ is the end of the law for righteousness to everyone who believes. (Romans 10:4)
When you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions, having canceled out the certificate of debt consisting of decrees against us, which was hostile to us; and He has taken it out of the way, having nailed it to the cross. (Colossians 2:13-14)
For while we were in the flesh, the sinful passions, which were aroused by the Law, were at work in the members of our body to bear fruit for death. But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter. (Romans 7:5-6)
For, on the one hand, there is a setting aside of a former commandment because of its weakness and uselessness (for the Law made nothing perfect), and on the other hand there is a bringing in of a better hope, through which we draw near to God. (Hebrews 7:18-19)
Love does no wrong to a neighbor;
therefore love is the fulfillment of the law. (Romans 13:10)
And so on and so on it keeps going but I think you get the point.
I think getting back to the OP, we are all God's children under Christ. We have been redeemed together, we share in his mercy together and we share his message together. Our spirits have no flesh and we are spiritual beings. This flesh we have is merely clothing that will be shed in when we pass from this life.
However, fear not. With the advent of the internet, people with your ideals are getting together and pooling their resources and some establish their own communities where they can keep their purity. You just have to make sure to get new converts or the blood will get a little too pure if you know what I mean. Maybe some want it that way, I don't know but good luck with the whole master race thing. Sorry it has no Biblical foundation.
