The thing everyone is missing is the holiness of the day. Made holy before sin, and mandated to be kept holy by those to whom it was given... That is mankind. It is still holy. Not holy in and of itself, but holy because of the blessing placed upon it, and the presence of God within it. Remembering to keep it holy is incumbent upon every child of God, Jew or Gentile, as a recognition and confession that He alone is the Creator of all things, and Redeemer of all men.
“9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: 10 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy. ”
1 Peter 2:9-10 KJV

Who is Peter addressing here? The same people Jesus is addressing here...
You really believe that God, through His Son, hadn't entered into covenant with you and I?
“26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body. 27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; 28 For this is my blood of the new testament, which is shed for many for the remission of sins. ”

Now read Hebrews 9.
Now try and convince all the readers that God hasn't made a covenant with His church.
I think you are just throwing stuff out there in the hope some of it sticks. Like your previous scriptures that say nothing at all of any change to the Ten Commandments, and make no reference to the Sabbath as having been changed in nature, cancelled, or made optional.
I really do not think you are totally convinced yourself of your position, but too proud to admit it, having no real evidence that Jesus or the disciples or the apostles or the early church made any inspired change to the observance of the Sabbath.
Think for a moment or two. Please explain why the early church suffered no condemnation from the Jews for abandoning the Sabbath.
