The whole Sabbath argument is just trash. It ignores history, ignores the Laws of Judaism, ignores what the Apostle Paul clearly stated in his Epistles, ignores the Church Fathers, ignores what the Ebionite/Judaizing heresies stood for.
The absurd source of support for the Sabbath hoax is "The Great Controversy," a trashy and utterly deceitful, lowbrow conspiracy theory rant. It is a 90 percent plagiarized bilge of lies and paranoid Catholic and Jew hatred, that has been investigated as a Hate Crime in parts of Canada. It ignores the entire history of the Eastern Orthodox church and its claims, and is a stitched together a colossus of fraud of irrelevant historical incidents.
That the writer is a proven false prophet becomes evident when the Seventh Day Adventists quote from the Baptist Confession of Faith for alleged support for the 7th Day Sabbath, and rename the Book for general public distribution, or leave the Prophet's name off of it altogether.
I think that's exactly what Paul says -
3 As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,
4 Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.
5 Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:
6 From which some having swerved have turned aside unto vain jangling;
7 Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.
8 But we know that the law is good, if a man use it lawfully;
9 Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,
10 For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;
11 According to the glorious gospel of the blessed God, which was committed to my trust.
1 Tim
4 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
4 For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:
5 For it is sanctified by the word of God and prayer.
6 If thou put the brethren in remembrance of these things, thou shalt be a good minister of Jesus Christ, nourished up in the words of faith and of good doctrine, whereunto thou hast attained.
7 But refuse profane and old wives' fables, and exercise thyself rather unto godliness.
8 For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.
9 This is a faithful saying and worthy of all acceptation.
10 For therefore we both labour and suffer reproach, because we trust in the living God, who is the Saviour of all men, specially of those that believe.
11 These things command and teach. 1 Tim
9 Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.
10 For there are many unruly and vain talkers and deceivers, specially they of the circumcision:
11 Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake.
12 One of themselves, even a prophet of their own, said, the Cretians are alway liars, evil beasts, slow bellies.
13 This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;
14 Not giving heed to Jewish fables, and commandments of men, that turn from the truth.
15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate. Titus 1
