Did you read that from your own set of gold plates?
Again, that is not what Scripture says.
The TRUTH is in the Church, guided by the Holy Spirit, to the end of time.
And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. Mat 6:18
I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. John 16:12-13
But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth. 1Tim 3:15
You mean this ecclesia & all its future generations until Messiah returns after the final trump?
Deut 4: 1 Now, O Israel, listen to the statutes and the judgments which I teach you to observe, that you may live, and go in and possess the land which the LORD God of your fathers is giving you. 2 You shall not add to the word which I command you, nor take from it, that you may keep the commandments of the LORD your God which I command you.
Deut 6 The Greatest Commandment
1 Now this is the commandment, and these are the statutes and judgments which the LORD your God has commanded to teach you, that you may observe them in the land which you are crossing over to possess, 2 that you may fear the LORD your God, to keep all His statutes and His commandments which I command you, you and your son and your grandson, all the days of your life, and that your days may be prolonged. 3 Therefore hear, O Israel, and be careful to observe it, that it may be well with you, and that you may multiply greatly as the LORD God of your fathers has promised youa land flowing with milk and honey.
4 Hear, O Israel: The LORD our God, the LORD is one! 5 You shall love the LORD your God with all your heart, with all your soul, and with all your strength.
6 And these words which I command you today shall be in your heart. 7 You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. 8 You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. 9 You shall write them on the doorposts of your house and on your gates.
Deut 29:14 I make this covenant and this oath, not with you alone, 15 but with him who stands here with us today before the LORD our God, as well as with him who is not here with us today (all future generations until Messiah returns)
Christianity is not Messiah's ecclesia however, a multitude of HIS children remain in Christian ecclesias out of blindness. Darn, there's that pesky blind in part thing sticking it's nose in our faces again.
Eph 4:11 Furthermore, he gave some people as emissaries, some as prophets, some as proclaimers of the Good News, and some as shepherds and teachers. 12 Their task is to equip God's people for the work of service that builds the body of the Messiah, 13 until we all arrive at the unity implied by trusting and knowing the Son of God, at full manhood, at the standard of maturity set by the Messiah's perfection. 14 We will then no longer be infants tossed about by the waves and blown along by every wind of teaching, at the mercy of people clever in devising ways to deceive...17 Therefore I say this - indeed, in union with the Lord I insist on it: do not live any longer as the pagans live, with their sterile ways of thinking. 18 Their intelligence has been shrouded in darkness, and they are estranged from the life of God, because of the ignorance in them, which in turn comes from resisting God's will...21 If you really listened to him and were instructed about him, then you learned that since what is in Yeshua is truth, 22 then, so far as your former way of life is concerned, you must strip off your old nature, because your old nature is thoroughly rotted by its deceptive desires; 23 and you must let your spirits and minds keep being renewed, 24 and clothe yourselves with the new nature created to be godly, which expresses itself in the righteousness and holiness that flow from the truth. 25 Therefore, stripping off falsehood, let everyone speak truth with his neighbor, because we are intimately related to each other as parts of a body.
Ignatius 110 A.D. wrote in his epistle to the Magnesians 9 " If they who were concerned in old things, arrived at a newness of hope, no longer observing the Sabbath, but living according to the Lords day, by which our life sprung from him and by his death (whom certain persons deny) we have been made his disciples, let us live according to Christianity."
Socrates Scholasticus, a church historian of the fifth century A.D., "For although almost all churches throughout the world celebrate the sacred mysteries [the Lord's Supper] on the sabbath of every week, yet the Christians of Alexandria and at Rome, on account of some ancient tradition, have ceased to do this."
"On the venerable Day of the Sun(Sunday) let the magistrates and people residing in cities rest, and let all workshops be closed. In the country, however, persons engaged in agriculture may freely and lawfully continue their pursuits; because it often happens that another day is not so suitable for grain-sowing or for vine-planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost. (Given the 7th day of March, Crispus and Constantine being consuls each of them for the second time [A.D. 321].)
"When the question relative to the sacred festival of Easter arose, it was universally thought that it would be convenient that all should keep the feast on one day; for what could be more beautiful and more desirable than to see this festival, through which we receive the hope of immortality celebrated by all with one accord and in the same manner? It was declared to be particularly unworthy for this, the holiest of festivals to follow the customs (the calculation) of the Jews, who had soiled their hand with the most fearful of crimes, and whose minds were blinded in rejecting their custom, we may transmit to our descendants the legitimate mode of celebrating Easter; which we have observed from the time of the Saviour's passion (according to the day of the week).
We ought not therefore to have anything in common with the Jews, for the Savior has shown us another way; our worship following a more legitimate and more convenient course (the order of the days of the week): And consequently In unanimously adopting this mode, we desire, dearest brethren to separate ourselves [Eusebius, Vita ConsL, Lib 11118-20)]
It was not YHVH's children who separated themselves from YHVH, it was Christendom who chose a different path for conveniences sake in order to please pagans & add their body count to its membership. The house of Judah may still be blinded as to YHVH the Messiah who walked among us as a man named Yah'shua, but they are and have always been in covenant.
Romans 11:25 For, brothers, I want you to understand this truth which God formerly concealed but has now revealed, so that you won't imagine you know more than you actually do. It is that stoniness, to a degree, has come upon Isra'el(house of Judah), until the Gentile world enters in its fullness
It is not for man to bring the house of Judah out of blindness, that task strictly belongs to Messiah who is YHVH.
May the use of YHVH's words & Christian historians, that are not taken out of context, be pleasing to HIM. God Bless
