Well the point on topic is Sabbath keeping was Jewish Law.
I prefer just to revisit Hebrews 4:9, though the term "rediscovered" might be appropriate in how it is being used, lol.
Hebrews 4:9
King James Version (KJV)
9 There remaineth therefore a rest to the people of God.
The "rest" here has nothing to do with the Sabbath of the Law.
The Sabbath was alien to gentiles so much James had to explain it to them.
James makes no mention of the Sabbath, he addresses whether Gentiles had to keep the Law in general.
The short answer is no, because both Jew and Gentile are saved by grace through faith...
...not through works:
Hebrews 4
King James Version (KJV)
9 There remaineth therefore a rest to the people of God.
10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
The point the writer is making is that those who fell in the Wilderness did not enter into the rest promised them because they were unbelievers, and likewise, those who do not believe in the writer's day will likewise not enter into the Rest which was foretold by Scripture (first in the promise given them by God as they were in the Wilderness, then through David, which again his point being...that wasn't the ultimate rest of Prophecy).
John 7
23“If a man receives circumcision on
the Sabbath so that the
Law of Moses will not be broken, are you angry with Me because I made an entire man well on
the Sabbath?
Acts 15
1Some men came down from Judea and
began teaching the brethren, “Unless you are circumcised according to the
custom of Moses, you cannot be saved.”
Christ's point is that the Priests...worked on the Sabbath. Yet His detractors condemned Him for healing a man.
Again, this has nothing to do with what the Writer of Hebrews is conveying to us.
There is a reason Jesus calls circumcision on sabbath Law of Moses rather then Law of Abraham.
There is a reason the Judaizers call it according to the custom of Moses.
The custom of Moses is what is at stake here. And part of the custom of Moses is the Sabbath keeping.
It is "the Law of Moses," which is not what the Covenant of Law was. Moses did not establish the Covenant, God did. Similarly Christ stated "You have heard it said," which distinguishes what is written from what is said, or...oral tradition and the doctrines of men.
Circumcision predates the Covenant of Law, so we get into a little more complicated issue, I feel. Think about it, one could argue that because it predates the Law (which was abrogated in light of the establishment of the New Covenant)...it should still be carried out.
But again, this is not relevant to the passage in view. The attempt to use this passage to undergird legalism is absurd.
Acts 15
28“For it seemed good to the Holy Spirit and to us to lay upon you no greater burden than these essentials:
29that you abstain from things sacrificed to idols and from blood and from things strangled and from fornication; if you keep yourselves free from such things, you will do well. Farewell.”
You think they would have mentioned the essential burden of Sabbath keeping.
Why?
If you notice, James does not say "If you do these things you will be saved," but, "...you will do well."
In view is interaction between Gentiles and Jews, a volatile issue in this day, and we can see that adherence to the Law earned Peter the title of Hypocrite (Galatians 2:9-14). They, the Gentiles, would do well in this interaction if they did not offend the sensibilities of people who had their entire lives lived under Law. Secondly, there is no command for a Jew to throw off his heritage. If a Jew decided he would still not eat unclean animals, that was his right. If he decided to observe Passover, that was his right.
The problem was with the Judaizers telling Gentiles they must adhere to the Law in order to be saved.
And that is in conflict with the Gospel of Christ.
I would be impressed to see this. With all phones, TV's, cable, internet, electricity, water all turned off as to not cause others to work ect.
Christ made it clear that to do good on the Sabbath, even if it appeared to be "work," was the will of God. That was, in fact, the point of the Law altogether. That men would love God and love their fellow man as God loves them.
But we go back to what the Writer of Hebrews states and see that when one enters into the Rest promised by God there is a completion of "works."
Hebrews 4
King James Version (KJV)
9 There remaineth therefore a rest to the people of God.
10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
Again, to try to use this as a proof-text for Sabbath Keeping defiles this Chapter and Book, and stands in direct contradiction with what Paul taught here:
Colossians 2:16
King James Version (KJV)
16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
God bless.
