——>Thus according to your hermeneutic, all instances of law-keeping in the NT means that all such are commanded.
Luke makes it clear that the 4th commandment/literal and physical observance of the 7th-day-Sabbath, is a binding moral commandment, even after the death of Christ, making it clear that His 10 commandment law was certainly not nailed to the cross. It stands then, as it does today exactly as written by the finger of preincarnate Jesus Christ.
As clear as mud you mean. The premise that recorded instances of law-keeping in the NT means does not that all such are commanded. Meanwhile,
THE NINE "MORAL" COMMANDS OF THE 10 COMMANDMENTS ARE REITERATED in the New Testament:
1). To worship the Lord God only (1st commandment): no less than 50 times
2). Idolatry (2nd commandment): condemned 12 times
3). Profanity (3rd commandment): condemned 4 times
4). Honoring parents (5th commandment) is taught 6 times
5). Murder (6th commandment) condemned 6 times
6). Adultery (7th commandment) condemned 12 times
7). Theft (8th commandment) condemned 4 times
8). False Witness (9th commandment) condemned 4 times
9). Covetousness (10th commandment) condemned 9 times
* see references here *Why is it that the duty to keep the Seventh day as Sabbath [as a command enjoined for believers under the N.C., versus simply recording acting as under the Old] is not mentioned ONCE in the New Testament?
WHEN THE NEW TESTAMENT LISTS SINS, SABBATH BREAKING IS CONSPICUOUSLY ABSENT:
In Mark 7:21-22 13 sins are listed. Jesus did not mention breaking the Sabbath.
In Romans 1:29-32 20 sins are listed and not one of them is Sabbath breaking.
In Galatians 5:19-21 a list of 15 sins are given,
In 2 Timothy 3:1-4 there's a list of 18 sins, but not once is Sabbath breaking mentioned!
WHY IS IT THAT NOWHERE IN THE NEW TESTAMENT IS IT TAUGHT THAT THE FOURTH COMMANDMENT MUST BE OBSERVED?
-Why is it that nowhere in the New Testament is failure to keep the Sabbath day condemned as sin?
-Why is the fourth commandment itself not repeated even ONCE in the New Testament?
-If the Sabbath keeping is so important for a disciple of Christ, why was it not mentioned in His sermon on the Mount or in ANY of His teachings?
-Why didn't Jesus command Sabbath keeping?
-Why didn't any of the Apostles command Sabbath keeping?
-Why didn't the Jerusalem counsel command Sabbath keeping or condemn Sabbath breaking? (Acts 15)
Some answer that the Jews already knew about the Sabbath so it was taken for granted that they would continue to keep it, but then why were the other nine commandments reiterated? Would they not be taken for granted as well? It would also seem that with so many Gentiles coming into the Church, that if keeping the Sabbath was so important there would be instruction in the New Testament Epistles somewhere concerning it. There are instructions for them concerning morality, ethics, worship, Church order and family lifestyle. Why would something as important as Sabbath keeping be ignored? Circumcision, which predates the Law and the Sabbath commandment was an issue in the New Testament Church and is addressed repeatedly in the New Testament Epistles and by the Jerusalem Counsel.
Sabbath keepers argue that it is the example of Jesus that gives us the reason for keeping the Sabbath. "He kept the Sabbath, so I must keep the Sabbath. Jesus is my example," they say. Well this kind of reasoning is flawed because it only chooses Jesus' Sabbath keeping and rejects the rest of His Jewish lifestyle. Jesus also kept Kosher laws. He kept the Passover, Sukkot, Hanukkah, and worshipped in the temple.
