Jesus said that He was the Lord of the Sabbath and that He fulfilled the Law.
The disciples kept Domenica holy as is very clear in
Let no one, then, pass judgment on you in matters of food and drink or with regard to a festival or new moon or Sabbath (Col. 2:16)
The New Testament fulfilled the Law. Love God and your neighbour is reflected in the other commandments.
Ah yes, the go-to verse to desperately seek a loophole to get out of Gods Holy Law. There were holidays (holy days) then just as now. As a Christian are you mandated or forbidden to observe Christmas(?) or the Fourth of July? Or is it up to you? Emperors famously declared their birthdays or some war memorial a holiday. As far as the Sabbaths referred to here, there are two additional Sabbaths mentioned in the OT for the Israelite s to keep. Nothing much to see here. The Ten Commandments are a unit wrote by the Hand of God on stone signifying permanence. There is a copy in Heaven in the Ark of the heavenly Covenant.
Jesus kept the Sabbath. Are you greater than He or know more than He did(does)?
