Of course - I don’t read your New World Translation.
As I wrote - Jesus was not a sabbatarian. On the contrary He was Lord of the Sabbath
Jesus rose from the dead “on the first day of the week.” Because it is the “first day,” the day of Christ’s Resurrection recalls the first creation. Because it is the “eighth day” following the sabbath, it symbolizes the new creation ushered in by Christ’s Resurrection. For Christians it has become the first of all days, the first of all feasts, the Lord’s Day (he kuriake hemera, dies dominica)
“Upon the first day of the weekσαββατων let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come” (1 Cor. 16:2 AV).
Now if you think Paul changed Christianity, do you reject the Pauline epistles?
Which means He rested (in death) on the Sabbath like a good Sabbatarian. He arose on the first day of the week after observance of the Sabbath but you use twisted pretzel logic to say He changed the day of worship mentioned in the Law. You say. What does the Bible (Jesus) say? Matt 5:17 “Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.
You say He changed it. He didn't. Do not embarrass yourself further. It's all there in the Bible for those willing to read and understand.
