Isaiah58
13If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
14Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken it.
Isaiah 66:23
And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
Jeremiah 17
21Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
22Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
23But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction.
24And it shall come to pass, if ye diligently hearken unto me, saith the LORD, to bring in no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein;
25Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes, the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever.
26And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and meat offerings, and incense, and bringing sacrifices of praise, unto the house of the LORD.
27But if ye will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.
Ezekiel20
10Wherefore I caused them to go forth out of the land of Egypt, and brought them into the wilderness.
11And I gave them my statutes, and shewed them my judgments, which if a man do, he shall even live in them.
12Moreover also I gave them my sabbaths, to be a sign between me and them, that they might know that I am the LORD that sanctify them.
13But the house of Israel rebelled against me in the wilderness: they walked not in my statutes, and they despised my judgments, which if a man do, he shall even live in them; and my sabbaths they greatly polluted: then I said, I would pour out my fury upon them in the wilderness, to consume them.
Ezekiel 22:8
Thou hast despised mine holy things, and hast profaned my sabbaths.
Ezekiel 22:26
Her priests have violated my law, and have profaned mine holy things: they have put no difference between the holy and profane, neither have they shewed difference between the unclean and the clean, and have hid their eyes from my sabbaths, and I am profaned among them.
Ezekiel 23:38
Moreover this they have done unto me: they have defiled my sanctuary in the same day, and have profaned my sabbaths.
Ezekiel 44:24
And in controversy they shall stand in judgment; and they shall judge it according to my judgments: and they shall keep my laws and my statutes in all mine assemblies; and they shall hallow my sabbaths.
It is completely bypassing life in Christ, and focusing instead on the appearance of language and belief, and sets itself above others. SDA sets itself up as right above everyone else, so this sentiment is continually coming through but bypassing the interior life with Christ.
Jn.14
15If ye love me, keep my commandments.
