If you believe Christians are obligated to observe the Sabbath by resting on the seventh day of the week, then you are free to your opinion--but your opinion on that matter doesn't change the fact that Sabbatarianism is restricted to certain areas in order to avoid clogging the system with Sabbath threads.
Suffice to say, the Christian Church, since the days of the Apostles, has confessed that Christians are under no compulsion to observe the Torah which had been given exclusively to the Jews as part of the covenant God made with them at Sinai. Which is why St. Paul says not to let anyone judge us concerning sabbaths, new moons, feasts, foods, and drink. Christians are not under the covenant which God made with the nation of Israel through Moses; we are under the covenant which is in Christ which is in His shed blood on the cross.
If I want to observe the Jewish Sabbath I'll convert to Judaism. But I have no intention on doing so, since I am a Christian.

I believe Christians are free to observe “Sabbaths’ Feast of Christ the Substance, eating and drinking of Him, the Nourishment (of Sabbaths) ministered”, “For if JESUS gave them Rest”—gave them Himself, Himself being “the Rest-of-God”, “God thus concerning the Seventh Day having spoken … by the Son … And God on the day The Seventh Day from ALL, HIS, WORKS, rested.” … “There THEREFORE, for the People of God remains (obligatory) Sabbath-Day-of-Rest.”
I am not free to an opinion of mine own. The Scriptures are binding on and over, my opinion or intention, as well as conscience.
Suffice to say, that Christians are under no compulsion to observe the Torah. Who said they are? Some deluded Sabbatharians maybe; no Christian believing Christ’s Resurrection “on the Sabbath”!
And who disclaimed the Torah had been given exclusively to the Jews as part of the covenant God made with them at Sinai? No Christian in his right senses!
Now Paul does not say not to <<let anyone judge us concerning sabbaths, new moons, feasts, foods, and drink.>> Every word is incorrect against what Paul actually wrote.
Nevertheless, even had Paul written what you are saying, so what?! <<Let not anyone judge us concerning sabbaths, new moons, feasts, foods, and drink>>! He or they judging you have no authority over you, Christians, “with regard to your eating or drinking of Sabbaths’ Feast”! Let them go jump in the lake; they have no say over you!
But sorry to differ with you, CryptoLutheran, but Christians are in truth under the same Covenant which God made with the nation of Israel through Moses. Christians are under the Only Covenant of Grace, <<which is in Christ which is in His shed blood on the cross>> and under which God saved the children of Israel. No one ever saved has ever been saved under or in or by or through another Covenant—another Gospel—another Saviour.
[I don’t know about Lutherans nowadays that they are returned to mamma Rome’s universal warm embrace.]
So you’re quite right, If you want to observe the Jewish Sabbath you'll have to convert to Judaism, because you won’t find it in the whole of the Bible. But I’m happy to hear you have no intention on doing so, since you are a Christian. Thank God.
