Wrong. God made the Sinai covenant with Israel, colloquially (though incorrectly) referred to as "the Jews".
Wrong. They are part of the Sinai covenant, which is the "first" covenant referred to in Hebrews 8:13.
"So when the Jews went out of the synagogue, the
Gentiles begged that these words might be preached to them the next Sabbath..." (Acts 13:42)
Q: God set only one specific day apart from the rest and blessed it, sanctified it and hallowed it. Which day would that be?
"1. In the beginning was the Word, and the Word was with God, and the Word was God. 2. The same was in the beginning with God." (John 1:1-2) The Ten Commandments were with us at Creation, "Abraham obeyed My voice and kept My charge, My commandments, My statutes, and MY laws." (Genesis 26:5) God established the 4th Commandment on the 7th day of creation. "Remember the Sabbath and keep it holy..." (Exodus 20:2-17 & Deut 5:6-21) and there are more.
The Ten Commandments were given to Moses by God, Moses did not write them, He was to give the Law to the people nothing more.
Jesus is our sacrificial lamb, and that's why we're not under the old mosaic laws, "Think not that I am come to destroy the law, or the prophets. I am not come to destroy but to fulfil. (Matt 5:17) We always have and always will be under Gods Commandments and Laws, even on the New Earth, "...and from one sabbath to another, shall all flesh come to worship before me, saith the Lord." (Isaiah 66:23)
Q: Do most Christians even know the history of Sunday worship or just follow along blindly?
*The Protestant reformation, *Constine and Sun worship, *The Roman Catholic Church.
Look up the Sabbath at BibbleTools.org, love you, always seek the truth & Gog speed Danny.
You stated,"
The requirements of Sabbath observance have been transferred to the first day of the week (the Christian Sabbath)." Show me this in the Bible, there has never been a transference of The True Sabbath to Sunday except by the Roman Catholic Church. and even they say that is not by any Scripture but by their own authority. From Creation God said he set one specific day apart from the rest and blessed it sanctified if and hallowed it, that day would be the 7th day of the week not the first. *The Protestant reformation, *Constine and Sun worship, *The Roman Catholic Church, all had to do with the Sunday worship that is observed today, it has nothing to do with Scripture. Organized Sunday worship is not Biblical, it is a counterfeit, a golden calf.
"He that saith, I know him, and keepeth not his Commandments, is a liar and the truth is not in him." (1 John 2:4)
Q: Is tradition greater than Scripture?
