Christ said to take his yoke upon ourselves because his yoke is easy and the burden is light, Matt 11:29-30. So if you think Christ is keeping the Sabbath for you, he basically said join him.
I had told someone else in the comment before this one that the Sabbath is not a philosophy, empty deception, human tradition, or the spiritual forces of the
world.
Messiah did warn about doctrines of men and rebuked the scribes and the Pharisees for it. What do you think he would say to those who are doing the exact same thing?
Matt 15
3Jesus replied,
“And why do you break the command of God for the sake of your tradition? 4For God said, ‘Honor your father and mother’ and ‘Anyone who curses his father or mother must be put to death.’
5But you say that if anyone says to his father or mother, ‘Whatever you would have received from me is a gift devoted to God,’
6he need not honor his father or mother with it.
Thus you nullify the word of God for the sake of your tradition. 7You hypocrites! Isaiah prophesied correctly about you:
8‘These people honor Me with their lips,
but their hearts are far from Me.
9They worship Me in vain;
they teach as doctrine the precepts of men.’”
Matt 5
19So then, whoever breaks one of the least of these commandments and teaches others to do likewise will be called least in the kingdom of heaven; but whoever practices and teaches them will be called great in the kingdom of heaven.
20For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.
And I don't want to make this an overly long response, but it's pretty clear Jesus believed the 10 commandments were extremely important.
Mark 10
17As Jesus started on His way, a man ran up and knelt before Him. “Good Teacher,” he asked,
“what must I do to inherit eternal life?”
18“Why do you call Me good?” Jesus replied. “No one is good except God alone.
19You know the commandments: ‘Do not murder, do not commit adultery, do not steal, do not bear false witness, do not cheat others, honor your father and mother.’”
