Don't know what they believe but I know what I believe concerning God's Truth.
Romans 14:5-9
Who is anyone to pass judgment upon another?: Romans 14:1-4 God is our only Judge when it comes to eternal life or hell.
While true, that's an incomplete picture, and doesn't address the topic of the sabbath day.
"One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind. 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. For none of us liveth to himself, and no man dieth to himself. For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord's. For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living."
Hence, Col. 2:16,
"Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ."
However, in quoting that, we must remember also that the
"sabbath was made for man" not only as a holy day, but a day of rest, having spiritual/eternal relevance to the believer who is promised to attain this rest with our Lord in paradise. It's God's time. A rest for our souls. It was the intended eternal life of Adam, before his sin, and before Eve's pro-creation. Now a gift for many, for the 'world'. - The Lord being the perfected Adam, and Lord of the Sabbath, and the groom of the wedding. Thus, the sabbath is and will be eternally true, but also a kind of rehearsal for the final ceremony when the church meets the Lord (a recurring theme in Scripture). Thus the Law/Torah/OC and the NC promise/'Gospel' are the same thing, two sides of the same coin. Part 1 and Part 2 of the same story. Therefore, if a person loves God, he will understand this and keep his law, instruction, commandment, or 'yoke' and receives the blessing of his promise. Life everlasting. The will of God, as expressed by his very lips.
"I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls." (Mt. 11:28-29)
In practice, the
weekly sabbath is symbol of salvation, liberation/non-enslavement to the world, not doing 'servile work'. However, w
eekly Sunday worship is arguably illegitimate, although legal, legitimate, and acceptable on certain days of the year, per the timing that the Apostles gathered after the Lord's burial, after the sabbath day, and after the Passover...
"There remaineth therefore a rest to the people of God. For he that is entered into his rest, he also hath ceased from his own works, as God did from his. Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief." (Heb. 49-11)
