You did not comment on the Colossians text which speaks on the sabbath keeping, plus the fact that it is never mentioned in the NT that Christians are to keep the Sabbath. In fact, also remember that James and the leaders when sending the people and the letter to the Gentiles in Acts 15:22-29
Then it pleased the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas, namely, Judas who was also named Barsabas, and Silas, leading men among the brethren.23 They wrote this letter by them:The apostles, the elders, and the brethren,To the brethren who are of the Gentiles in Antioch, Syria, and Cilicia: Greetings. 24 Since we have heard that some who went out from us have troubled you with words, unsettling your souls, saying, “You must be circumcised and keep the law —to whom we gave no such commandment— 25 it seemed good to us, being assembled with one accord, to send chosen men to you with our beloved Barnabas and Paul, 26 men who have risked their lives for the name of our Lord Jesus Christ. 27 We have therefore sent Judas and Silas, who will also report the same things by word of mouth. 28 For it seemed good to the Holy Spirit, and to us, to lay upon you no greater burden than these necessary things: 29 that you abstain from things offered to idols, from blood, from things strangled, and from sexual immorality. If you keep yourselves from these, you will do well.Then it pleased the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas, namely, Judas who was also named Barsabas, and Silas, leading men among the brethren.
If it seemed with the Holy Spirit and all the church leaders not to mention any other things that the Gentiles needed to add, it should be good enough for anyone who is concerned about the matters, whatever they may be concerning keeping any of the law. The passage in Colossians 2 was really clear also. But scripture does say whatever is not of faith is sin, so if it bothers anyone, they should do as their faith lead's them, but then obey the text in Colossians that it only applies to them and others that may feel the same way.
New Testament Evidence:
YahuShua (Jesus) The Messiah Honored the Sabbath
YahuShua (Jesus) The Messiah and His disciples kept the Sabbath as commanded in the 4th commandment. YahuShua (Jesus) not only kept all of the commandments, but told us they will be kept forever, and that not even one of these commandments will pass away. As a person choosing to follow YahuShua (Jesus). His ways become our ways. The examples He gave us throughout His ministry on earth should also be kept today, without question. The New Testament gives us numerous examples of YahuShua (Jesus) honoring the Sabbath day:
Matthew 12:10-12 ~ It is Good to do Good on the Sabbath
(10) And behold, there was a man which had his hand withered. And they asked Him, saying, Is it lawful to heal on the Sabbath days? That they might accuse Him. (11) And He said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the Sabbath day, will he not lay hold of it, and lift it out? (12) How much then is a man better than a sheep? Wherefore it is lawful to do well on the Sabbath days.
Matthew 24:20-21 ~ The Sabbath Should Be Kept Even in the Last Days
(20) But pray ye that your flight be not in the winter, neither on the Sabbath day. (21) For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. (In this verse, Jesus is referring to the last days.)
New Testament Evidence:
Jesus Christ Honored the Sabbath
Mark 2:23-28 ~ Jesus is Lord of the Sabbath; The Fulfillment of Personal Needs is Allowed on the Sabbath (eating, sleeping, etc.)
(23) And it came to pass, that He went through the corn fields on the Sabbath day; and His disciples began, as they went, to pluck the ears of corn. (24) And the Pharisees said unto Him, Behold, why do they on the Sabbath day that which is not lawful? (25) And He said unto them, Have ye never read what David did, when he had need, and was an hungered, he, and they that were with him? (26) How he went into the house of God in the days of Abiathar the high priest, and did eat the shewbread, which is not lawful to eat but for the priests, and gave also to them which were with him? (27) And He said unto them, The Sabbath was made for man, and not man for the Sabbath. (28) Therefore the Son of Man is Lord also of the Sabbath.
Luke 4:16 ~ Jesus Taught On The Sabbath
And He came to Nazareth, where He had been brought up. And, as His custom was, He went into the synagogue on the Sabbath day, and stood up for to read.
Mark 3:1-5 ~ Jesus Helped Others on the Sabbath
(1) And He entered again into the synagogue, and there was a man there which has a withered hand. (2) And they watched Him, whether He would heal Him on the Sabbath day, that they might accuse Him. (3) And He saith unto the man which had the withered hand, Stand forth. (4) And He saith unto them, Is it lawful to do good on the Sabbath days, or to do evil? To save life, or to kill? But they held their peace. (5) And when He had looked round about on them with anger, being grieved for the hardness of their hearts, He saith unto the man, Stretch forth thine hand. And he stretched it out. And his hand was restored whole as the other.
Luke 23:55-56 ~ Jesus.. Disciples Rested and Kept the Sabbath, Even During Jesus’ Death, As He Also Kept the Sabbath Even in Death

Acts 13:14 ~ Christ’s Apostles Kept the Sabbath
But when they departed form Perga, they came to Antioch in Pisidia, and went into the synagogue on the Sabbath day, and sat down.
James 2:10-11 ~ In Breaking One of the Commandments, We Transgress the Whole Law
(10) For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. (11) For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the Law.
Luke 16:17 ~ The Law, the Ten Commandments, Will Never Pass Away
And it is easier for heaven and earth to pass, than one tittle of the Law to fail.
[Note: Jesus is saying it is easier for the skies (heaven) and earth to fade or be destroyed than even one point or word of the Law of God to be changed or destroyed. They are written as it were, in ..everlasting stone… The Ten Commandments stand forever; only the laws found in ordinances have passed away, having been nailed to the cross with Jesus. – Colossians 2:14]
New Testament Evidence:
Jesus Christ Honored the Sabbath, Even in Death
There are only eight references in the Bible to the first day of the week, none of them referring to the Sabbath (five of them refer to the day when the tomb was found empty). Jesus rose from the dead Saturday evening, having rested on the Sabbath, the last day of the week.
The Biblical Chronology of Jesus Christ’s Crucifixion and Resurrection
Tuesday: YahuShua (Jesus) The Messiah, ate an evening Passover meal with His disciples (at the beginning of Nisan 14*, biblical reckoning) and instituted the New Covenant symbols (Matthew 26:26-28). YahuShua (Jesus) was then betrayed by Judas, arrested and during the night brought before the high priest.
Wednesday: YahuShua (Jesus) was crucified and died around 3 p.m. (Matthew 27:46-50). This was the preparation day for the annual, not weekly, Sabbath, which began at sunset (Mark 15:42; Luke 23:54; John 19:31). YahuShua (Jesus) body was placed in the tomb just before sunset (Matthew 27:57-60).
Thursday: This was the high-day Sabbath, the first day of Unleavened Bread (John 19:31; Leviticus 23:4-7). It is described as the day after the ..Day of Preparation.. (Matthew 27:62).
Friday: The high-day Sabbath now past, the women bought and prepared spices for anointing Jesus.. body before resting on the weekly Sabbath day, which began at Friday sunset (Mark 16:1; Luke 23:56).
Saturday: The women rested on the weekly Sabbath, according to the Fourth Commandment (Luke 23:56; Exodus 20:8-11).YahuShua (Jesus) rose near sunset, exactly three days and three nights after burial, fulfilling the sign of Jonah and authenticating the sign He gave of His messiah-ship.
Sunday: The women brought the prepared spices early in the morning while it was still dark (Luke 24:1; John 20:1), finding that YahuShua (Jesus) had already risen (Matthew 28:1-6; Mark 16:2-6; Luke 24:2-3; John 20:1). He did not rise on Sunday morning, but near sunset the day before.
* Nisan is the first month of the civil year and the seventh month (eighth, in leap year) of the ecclesiastical year on the Hebrew calendar. **Also note that a Biblical day was from sunset to sunset.
