The Sabbath Day command has not been done away with.
Saying it doesn't make it so.
Colossians 2:16 So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, 17 which are a shadow of things to come, but the substance is of Christ. 18 Let no one cheat you of your reward, taking delight in false humility and worship of angels, intruding into those things which he has not seen, vainly puffed up by his fleshly mind, 19 and not holding fast to the Head, from whom all the body, nourished and knit together by joints and ligaments, grows with the increase that is from God.
20 Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations— 21 “Do not touch, do not taste, do not handle,” 22 which all concern things which perish with the using—according to the commandments and doctrines of men? 23 These things indeed have an appearance of wisdom in self-imposed religion, false humility, and neglect of the body, but are of no value against the indulgence of the flesh.

It's astounding to me the tenacity with which people cling to doctrines that are completely blown apart by the quotation of a single passage of scripture!
I mean, there's not even any argument that needs to be explained. No complex connects that need to be made between various passages in diverse places throughout the bible. It's literally as simple as reading two paragraphs in one book of the New Testament and you've got the whole thing settled.
I know that it won't convince you. You're convinced of your doctrine by things other than the plain reading of scripture - most people are. But this debate was over before it started. All you can do is make every attempt to explain away what Paul clearly states. That the sabbaths were a shadow of things to come. Those who are in Christ have entered into His rest, into the REAL Sabbath and have no need for such shadows any longer.
I just have the same question for you that Paul had for the Galatians...
Having begun in the Spirit, are you now being made perfect by the flesh?
Resting in Him,
