That is so wrong in so many ways. The Sabbath he is referring to is the one He blessed, sanctified and hallowed, the one he told us to remember and keep holy.
Who is
US? Exodus 20:2 - I am the Lord your God, who brought
YOU out of the land of Egypt, out of the house of bondage. The Israelites.
Moses gives the reason the sabbath was given to the
nation of Israel: “Remember that you were slaves in Egypt and that the Lord your God brought YOU out of there with a mighty hand and an outstretched arm. Therefore, the Lord your God has commanded YOU to observe the Sabbath day.” (Deuteronomy 5:15)
Sabbath observance was a
sign between God and Israel: “The
Israelites are to observe the Sabbath, celebrating it for the generations to come as a lasting covenant. It will be a
sign between me and the Israelites forever, for in six days the Lord made the heavens and the earth, and on the seventh day he abstained from work and rested.” (Exodus 31:16-17)
Your statement on Sabbatarians is obdured, you presume way too much. and again, he is telling us that the sabbath will be observed. your last statement, I have no idea what you're saying, that has to be the most far-reaching thing I have ever heard. The Ten Commandments are not part of the old mosaic Law and the new covenant did not abolish Gods Law just the Law of Moses.
The law of Moses does include the Ten Commandments since the Ten Commandments are major set of laws within the Law of Moses.
Nehemiah 9:14 - So, You made known to them Your holy
sabbath, and laid down for them
commandments, statutes and
law,
Through Your servant Moses.
1 Kings 2:3 - Keep the charge of the Lord your God, to walk in His ways, to keep His statutes, His
commandments, His ordinances, and His testimonies,
according to what is written in the Law of Moses, that you may succeed in all that you do and wherever you turn.
Matthew 12:5 - Or have you not read
in the Law, that
on the Sabbath the priests in the temple
break the Sabbath and are innocent?
Matthew 22:36 - “Teacher, which is the great
commandment in the law?” 37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ 38 This is the first and great commandment. 39 And the second is like it: ‘You shall love your neighbor as yourself.’ 40
On these two commandments hang all the Law and the Prophets.”
In James 2:15-16, the example of a "work" that James gives is: "If a brother or sister is naked and destitute of daily food, and one of you says to them, "Depart in peace, be warmed and filled," but you do not give them the things which are needed for the body, what does it profit?" To give a brother or sister these things needed for the body would certainly be a "good work" yet to neglect such a brother or sister and not give them the things needed for the body is to
break the second great commandment "love your neighbor as yourself" (Matthew 22:39)
as found written in the law of Moses. (Leviticus 19:18)
James 2:11 - For He who said, “Do not commit adultery,” also said, “Do not murder.” Now
if you do not commit adultery, but you do murder, you have become a
transgressor of the law.
I have news for you. 2 Corinthians 3:6 - who also made us sufficient as ministers of the
new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. 7 But if the
ministry of death, written and engraved on stones, was glorious, so that the children of Israel could not look steadily at the face of Moses because of the glory of his countenance, which glory was passing away, 8 how will the ministry of the Spirit not be more glorious? 9
For if the ministry of condemnation had glory, the ministry of righteousness exceeds much more in glory.
Once again, it started with the protestant reformation when the Gentile believers wanted to separate themselves from the Jews because they were being persecuted by the Romans, so the changed there day of worship from the Sabbath to Sunday. (Notice that they where observing the true Sabbath and they changed it, not God.)
Next was the King / Emperor Constine who worshiped the Sun. (Is where we get the term Sunday) Constine made the first law for mandatory Sunday worship, and actually forbid most Sabbath keeping.
Then came the Roman Catholic church who has formed Sunday worship into what it is today. They even say that the Sabbath hasn't been changed by scripture and that there is no bases for Sunday observance except by the authority of the Church.
I am not buying into your SDA propaganda.
