Should have read the previous page. I posted this already.
Cutting it short and going straight to Romans 14:6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
The subject of eating is brought up twice in this chapter. It's sister passage can be found in 1Cor 8. The first time eating it is referring to meat sacrificed to idols and that some were confused and thought the meat became defiled by it being used in pagan sacrifice. But the second time it incorporates eating or not eating with the observance of particular days. No mention of the Sabbath whatsoever, The reason being is as new converts were entering to fold there was much confusion about what was done away with and what remained. Including feasting and fasting days, which is why the mention of eating and not eating on days were mentioned. Paul informs us that these feast and fasting days was up to the individual but no longer binding. Again no mention of the Sabbath or the ten commandments at all in this passage but people sure like to use it to explain why they don't need to keep the Sabbath.
Now as far as the subject goes about the confusion of what was done away with and what remained let's see what Hebrews was written for.
Heb 12:27 And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain.
So he is telling us that certain things were removed and certain things did indeed remain. And the purpose of this book is supposed to help us with that. So what does Hebrews say about the Sabbath?
Heb. 4:1 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.
2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
3 For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.
4 For he spake in a certain place of the
seventh day on this wise, And God did rest the
seventh day from all his works.
5 And in this place again, If they shall enter into my rest.
6 Seeing therefore it
remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
7 Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
8 For if Jesus had given them rest, then would he not afterward have spoken of another day.
9
There remaineth therefore a rest to the people of God.
10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
11 Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
The word rest in verse 9 is mentioned in Strong's concordance;
"4520 σαββατισμός sabbatismos sab-bat-is-mos’
