Matt. 12:
11 And he said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift
it out?
12 How much then is a man better than a sheep? Wherefore
it is lawful to
do well on the sabbath days.
It would be hard to argue that
rejecting His Sabbath would be considered by Him as "doing well" or "Lawful" on His Holy Sabbath that He created for man, the He followed, as well as His Apostles.
There is no mention of changing His Sabbath in the New Covenant HE promised in Jer. 31. Only how God's Laws are administered and how Sins are forgiven. He said He would write HIS, God's, the Word which became Flesh's Laws on our heart. It is man who teaches He abolished them, He said He writes them on our hearts, presumably so we wouldn't forget them********Again.
