What about the cattle, the servants, and the strangers that were visiting...were they Israelites? No. What of the Gentiles who were joined to Israel by adopting the Israelites' God as their own? Were they to keep Sabbath? Yes.
In Isaiah 56:2, we read that foreigners were to "join themselves to the Lord;" and "love the name of the Lord;" and "be his servants;" and "take hold of God's covenant." The OLD COVENANT. But to do this they had to be circumcised, for God said: "No foreigner uncircumcised in heart and uncircumcised in flesh, of all the foreigners who are among the sons of Israel, shall enter My sanctuary." (Ezekiel 44:9) When Gentiles thus "joined themselves to the Lord" they CEASED BEING GENTILES and became proselytes to the Jewish religion. They kept the Sabbath AS JEWISH PROSELYTES, NOT as Gentiles.
But WHERE ARE GENTILES as Gentiles ever commanded to keep the Sabbath? Furthermore, if the Sabbath was of universal application, why were the Gentiles called "strangers?" The apostle Paul, speaking of the Gentiles during the Jewish age, says they were "strangers from the covenants of promise, having no hope, and without God in the world?" (Ephesians 2:12)
And when God gave the Sabbath commandment at Sinai, why did he make it binding ONLY on "the stranger that is within your gates?" (Exodus 20:10) Where is the passage that proves the Sabbath was binding on the Gentile OUTSIDE the gates? All this shows the Sabbath was NOT universally applied. If it had been, there would have been no "strangers from the covenants of promise."
What of Gentiles in the NT era who are joined to Christ along with Jewish Cristian converts? Are we now not all Israel?
Not in a physical sense and not under the old covenant. Jew and Gentile alike who believe the gospel are united together into ONE BODY, the body of Christ. (Ephesians 1:13; 3:6; 1 Corinthians 12:13)
If we are to keep Sabbath i the new earth (see Isa.66) then where's the logic in dispensing with it today? Because that is what you are doing.
Where is it stated in Isaiah 66 that we are to keep the weekly sabbath day under the law in the new earth? Isaiah 66:22-23 simply teaches that from month to month and from week to week, God’s people will worship Him. In the new heaven and the new earth, we read there will have no need of the sun or moon, there will be no night there, but one perpetual day and the glory of God will illuminate it. (Revelation 21:23-25) How then could there be a cycle of seven days that would allow for literally keeping the weekly sabbath day under the law? The Isaiah passage simply means that God’s people will perpetually worship Him in contrast to keeping the weekly sabbath day under the law.
Furthermore, if one insists on sabbath observances based on Isaiah 66:23, then one also needs to observe new moons as well. Yet from what I hear, Sabbatarians don’t observe new moons, which is inconsistent. New moons require night, hence sabbatarians have night in heaven, yet there is no day and night cycles in heaven. You cannot have "new moon to new moon" or "sabbath days" without day and night, so the argument is moot.
Will there be Levitical priests in the new heaven? If Isaiah 66:23 teaches that we will keep the sabbath day in the new heaven, then it also teaches in Isaiah 66:21 that the Levitical priests will be in the new heaven, because it is also mentioned. What happened to the Levitical priesthood under the new covenant terms? Priesthood changed so did the law. Hebrews 7:12 - For when the priesthood is changed, the law must be changed also. *The old and new covenants do not mix.*
There is no explicit instruction anywhere in scripture, including Colossians 2, where the weekly Sabbath is said to be dispensed with.
There is no explicit instruction anywhere in the New Testament where the sabbath is commanded to be kept by the Church. In Colossians 2:16-17, we read - Therefore, no one is to act as your judge in regard to food and drink, or in respect to a festival or a new moon, or a
Sabbath day— things which are only a shadow of what is to come; but the substance belongs to Christ. Yet you act as my judge.
That is an invention of your own making, and historically began with the apostate church and compromising believers in the 2nd and 3rd centuries, and made ecclesiastical law by Rome in the 4th. If you reject Sabbath, you are appeasing Rome.
Typical SDA straw man argument. Seventh-day Adventists are so obsessed with the sabbath day that they teach the ludicrous doctrine that the near the end of time the "mark of the best" of Revelation 14 will be placed upon those who worship on Sunday instead of Saturday.
