Like I said before, you can't pick and choose WHICH Jewish laws in the bible you are going to follow and which ones you aren't. If you are bound to the law, it's the WHOLE law.
So - do you eat only kosher foods? Do you keep all the Jewish holy days? Do you take rebellious teens to the town square and stone them? All those laws and many more are in the Torah and the Christian Old Testament.
THE NEW TESTAMENT AND THE FIRST DAY OF THE WEEK
What we need to do is look at what transpired on the first day of the week and then look at the scriptural evidence for the assembly on the first day in the New Testament.
1. Jesus rose from the dead on the first day of the week after the Sabbath (John 20:1). He was the first fruit until eternal life others were also raised Mt.27:53. the resurrection is the capstone of our faith and the proving of the new covenant. he was raised for our justification.
2. Jesus appeared to ten of His disciples on that first day of the week (John 20:19).
3. Jesus waited one week, and on the next first day of the week appeared to the eleven disciples (John 20:26).
4. The promised coming of the Holy Spirit was fulfilled on the first day of the week, the day of Pentecost he was sent, (Pentecost by law came on the first day of the week (Lev. 23:16).
5. On the first day of the week the first gospel sermon preached by an apostle on the death and resurrection of Jesus was by Peter (Acts 2:14).
6. On that first day of the week the three thousand converts were united into the New Testament covenant separating from Judaism (Acts 2:41). While at the first Pentecost 3,000 were slain on this day God reversed it and instead they were given eternal life. The law kills the new covenant gives life.
7. On that same first day of the week the rite of Christian baptism into the Name of the Father, Son, and Holy Spirit was administered for the first time (Acts 2:41).
8. At Troas Paul preached to the assembled Christians on the first day of the week
The only example of the Lord's supper being practiced on Sunday (Acts 20:6, 7). So did the churches of Galatia and Corinth.
9. Paul instructed the Christians at Corinth to make contributions on the first day of the week (I Cor. 16:2).Why did Paul specifically give orders to the church for this to be done on the "first day of the week." Offerings are a part of worship itself. Offerings are a part of our worship and since offerings took place on the first day of the week, wouldn't it make sense that worship also took place on the same day of the week. This is only day in the New Testament that commands Christians to give, they would have to be gathered to do so.
If Sunday was not an allowable day to worship or teach on then none of this would have occurred.
There is a biblical numerology in which 7 is the number of completion (of rest) the week is completed in 7 days. The number 8 is a symbol of new beginnings. Both days were used as In Ex.12. given at the same time.
No one ever changed the Sabbath day to SUNDAY
The Sabbath commemorated a finished creation with rest. The first day commemorates a finished redemption and a new work.
The Sabbath commemorates Israels deliverance from Egyptian slavery and God resting on the 7th day. The first day commemorates Christs resurrection, victory over death and eternal punishment . It gives hope that all who believe will also be resurrected from the dead.
The Sabbath is a day of rest and quiet. The first day is a day of worship and praise. Sabbath means rest, not Saturday! There were other Sabbaths given to Israel on other days. The Sabbath was made for man to rest, God was telling Israel to keep the rest, their focus was not a day.
They changed the Sabbath to Sunday
