Catholics do not claim to worship on sunday due to a biblical command. If you had read the previous 100 plus posts you would realize this.
This verse says nothing about commanding a weekly sabbath observance. You inserted your definition of “holy”. You are using the word in a very limited sense. You limit this day God is talking about to a literal day of the week. Yet if you really read the scripture… God rested from his work of creation… it was finished. There is no comment of God beginning his work again in a cycle. “holy” in hebrew means more than set apart for special use. The root for holy is the same as prostitute… That seems a bit shocking. But a prostitute lives and works outside the normal boundaries of her society.

God is HOLY, he is outside the normal bound of our limited ability to understand him. He is infinite and we are finite. In making his rest from creation Holy, God placed his rest (literally his ceasing) outside the bounds of normal time and space, beyond the possibility of full human understanding. The seventh day is distinguished from the other six by more than rest and a blessing… As an Adventist, I always missed this critical difference until many years later. I wonder if you can find it?
Later, he gave his people as part of the Old Covenant a weekly reminder and symbol of his divine rest. That covenant is gone, fulfilled. While it is still find to respect the sabbath and keep it if you want… it is no longer mandatory. The Council of Jerusalem recorded in the book of Acts and St. Paul in his epistles make that very clear. Christians live under the New Covenant. Paul even says in Hebrews that the Jews were not able to enter into the divine rest through the works of the law. The divine rest is MORE than a specific day of the week. It is infinite. Jesus is our sabbath rest, only in him is the shadow fulfilled.
Did you notice the blessing is worded differently than the Creation story? sabbath means ‘cease’ not seventh. They also had other sabbaths that were not on saturday. There is no biblical distinction between the weekly sabbath and these other holy days. God also gave another reason for the weekly day of rest, Have you read the account of the Ten Commandments in Deuteronomy?
Deuteronomy 5:1-13
**2The LORD our God made a covenant with us in Horeb.
3The LORD made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
4The LORD talked with you face to face in the mount out of the midst of the fire,
5(I stood between the LORD and you at that time, to shew you the word of the LORD: for ye were afraid by reason of the fire, and went not up into the mount

saying,
6I am the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
7Thou shalt have none other gods before me.
8Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth:
9Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,
10And shewing mercy unto thousands of them that love me and keep my commandments.
11Thou shalt not take the name of the LORD thy God in vain: for the LORD will not hold him guiltless that taketh his name in vain.
12Keep the sabbath day to sanctify it, as the LORD thy God hath commanded thee.
13Six days thou shalt labour, and do all thy work:
14But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ***, nor any of thy cattle, nor thy stranger that is within thy gates; that thy manservant and thy maidservant may rest as well as thou.
15And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.

Two very important details to understanding the 7th day sabbath:
WHO is this covenant made with?
3The LORD made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
WHAT were they to remember?
****15And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
There are two remembrances in these two versions of the 10 commandments. Unless the bible is contradicting itself, which we both agree is not a good answer… why are there two reasons?
What do they have in common? NOT creation… and NOT freedom from slavery… So WHAT really were they to remember?
REST. That is the commonality of the two reasons. How do you enter into the divine rest? Under the old covenant… God gave them a finite day to enter into this divine reality. Under the new… We have God Himself in the person of His divine Son, Jesus.
The Jews failed to enter into this divine, HOLY beyond human conception, rest that was hidden in the shadow of a day…
Christians have Jesus, who is all Holy and we find our rest in Him.
Again, fulfilling the shadow.
Adventists make the mistake of taking something infinitely Holy and beyond human understanding, and trying to tie it to something very limited… a particular day of the week.
God Bless,
