Hello MMD,
WE are no longer under the Mosaic sabbath, and Paul speaks of ceremonial feast days and laws, which are fulfilled IN Christ.
The sabbath laws had become part of the ceremonial laws for that nation alone.
We are under Law to Christ. All 10 commandments are put in our heart. All the nations will answer to those laws.
I do not consider it a burden to give priority to the things of God, and works of mercy and necessity.
We get to worship and serve God. It is a pleasure, not a burden.

Appendix I
The Ceremonial Law
1. What is the Ceremonial Law?
The duties which the law of God as revealed through Moses demands of us, the Israelites, in particular, as the professors of its religion.
2. Upon what is this Law founded?
Upon the history of the Mosaic Religion, and of the people of Israel before and since the promulgation of the Ten Commandments from Sinai.
3. What is the object of the ceremonies?
The constant observance of the ceremonies is intended to remind us perpetually of the events upon which they are founded, and to cause their being handed over to our children after us, to the latest generations.
"Remember his miracles that He hath done, his wonders and the Judgments of his mouth. O ye seed of Israel, his servants; the children of Jacob, his chosen people. He is the Lord our God; his judgments are in all the earth. Remember ye his covenant for ever; the word which He commanded to a thousand generations. Which He covenanted with Abraham, and likewise his oath unto Isaac. And he confirmed the same to Jacob for a statute, to Israel for an everlasting covenant." Ps. cv. 5-10.
4. Which are the principal events of which the Ceremonial Law is to remind us?
The following three:
First, The Exodus, or removal, of our forefathers from Egypt.
Second, The Divine Revelation, and the promulgation of the Law on Sinai.
Third, The destruction of the temple at Jerusalem, and of the kingdom of Israel.
5. What observances are to remind us of the Exodus?
First, The Sabbath day, regarded as the sign of the covenant of the manifestation of God's power in Egypt.
"And remember that thou were a servant in the land of Egypt, and that the Lord thy God brought thee out thence, through a mighty hand, and by an outstretched arm: therefore the Lord thy God commanded thee to keep the Sabbath day." Deut. v. 15.
Second, Several others of the festivals.
18. How is the Day of Atonement to be observed?
On the tenth day of the seventh month is the great day of humiliation and prayer before the Lord. During the whole of its continuance, from sunset of the ninth till after the stars have appeared on the tenth, we shall abstain from food and drink, and all earthly enjoyments; and perform no manner of labor, just as on the weekly Sabbath. We shall seriously think over our past conduct, and offer up to God a contrite spirit for our manifold transgressions; if we have offended our neighbor we should satisfy him, before we ask forgiveness of the Lord; and it is for such repentance that we are promised a remission of sin, and an atonement for our iniquities.

Exodus 6
King James Version
6 Then the Lord said unto Moses, Now shalt thou see what I will do to Pharaoh: for with a strong hand shall he let them go, and with a strong hand shall he drive them out of his land.
2 And God spake unto Moses, and said unto him, I am the Lord:
3 And I appeared unto Abraham, unto Isaac, and unto Jacob, by the name of God Almighty, but by my name Jehovah was I not known to them.
4 And I have also established my covenant with them, to give them the land of Canaan, the land of their pilgrimage, wherein they were strangers.
5 And I have also heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant.
6 Wherefore say unto the children of Israel, I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will rid you out of their bondage, and I will redeem you with a stretched out arm, and with great judgments:
7 And I will take you to me for a people, and I will be to you a God: and ye shall know that I am the Lord your God, which bringeth you out from under the burdens of the Egyptians.
8 And I will bring you in unto the land, concerning the which I did swear to give it to Abraham, to Isaac, and to Jacob; and I will give it you for an heritage: I am the Lord.
9 And Moses spake so unto the children of Israel: but they hearkened not unto Moses for anguish of spirit, and for cruel bondage.
10 And the Lord spake unto Moses, saying,
11 Go in, speak unto Pharaoh king of Egypt, that he let the children of Israel go out of his land.
12 And Moses spake before the Lord, saying, Behold, the children of Israel have not hearkened unto me; how then shall Pharaoh hear me, who am of uncircumcised lips?
13 And the Lord spake unto Moses and unto Aaron, and gave them a charge unto the children of Israel, and unto Pharaoh king of Egypt, to bring the children of Israel out of the land of Egypt.
