My point is that it doesn’t matter whether the sabbath begins on Saturday or Sunday. If you want to put yourself under the sabbath law as God has given it to His people then to break it means death.
under the New Covenent Christians are not under the Old Covent law to keep them. And just as the Jews were unable to keep them, so are you.
You misunderstand the entire NT. Look at what Jesus and Paulo had roi say about traditions.
Mark 7: 1 THEN came together unto him the Pharisees, and certain of the scribes, which came from Jerusalem.
2
And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.
3
For the Pharisees, and all the Jews, except they wash their hands oft, eat not, holding the tradition of the elders.
4
And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brasen vessels, and of tables.
5 Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
6
He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8
For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
9
And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
10
For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
11
But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
12
And ye suffer him no more to do ought for his father or his mother;
13 Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
The Talmud which the Pharisees followed has hundreds of laws concerning hand washing, washing dishes, etc. They had thousands of laws governing every aspect of human behavior. There was nothing about life that was untouched. They also had hundreds of laws governing how to keep the Sabbath and accused Jesus of breaking the Sabbath when He healed people on Sabbath.
This is why Jesus called them hypocrites multiple times and told the people during the sermon on the mount that unless their righteousness exceeded the righteousness of the Pharisees they would never enter heaven.
Paul was a Pharisee. He went around killing and persecuting Christians before his conversion.
Galatians 1: 13 For ye have heard of my conversation in time past in the Jews’ religion, how that beyond measure I persecuted the church of God, and wasted it:
14 And profited in the Jews’ religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers.
Phillippians 3: 4 Though I might also have confidence in the flesh. If any other man thinketh that he hath whereof he might trust in the flesh, I more:
5
Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee;
6
Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
So does keeping the law of God cause a person to kill and persecute Christians? Was Paul blameless before the law of God? If not, to what law is he referring?
