Most Christians will agree that Paul makes it clear in Colossians 2:16, that these kinds of rules are not requirements for gentile believers. And that Paul goes into greater detail about it in Romans 14:1-10.
The SDA version is different of course.
Your only argument so far is most Christians don't agree with you. So you base you beliefs on what most Christians think. Thank God the Apostles did not base their beliefs on what others thought. Since we already established you have no argument against what was shown to you in regards to Romans 14. Let's take a look at the context in Colossians chapter 2 shall we?
Beware lest anyone spoil, steal us away. For we are complete in Him, established in the faith. Circumcised with the circumcision made without hands in the putting off the body of the sins of the flesh by the circumcision of Christ in Baptism wherein the body of the sins of the flesh is buried, put off. And we being dead in our sins and the uncircumcision of the flesh are now risen, quicken together with Him through Baptism, the circumcision made without hands; forgiving us of all trespasses through Faith in operation of God. Therefore Blotting out the handwriting of ordinances because we have been forgiven of our trespasses. For our sins have been cut off through the circumcision made without hands and the handwriting ordinances of judgment and condemnation that were against us were taken away and nailed to the cross because they are not needed anymore because we now have our forgiveness in Christ through the faith in the operation of God. Not the statutes and laws that told us what sin is, but the ordinances which were condemning; that dealt with when we sinned. And certainly not the Ten commandments and the Sabbath therein. For they also tell us what sin is.
Having spoiled the principalities, that which was established first, the handwriting of ordinances and it's power. That which was against us and contrary to us. Condemning us in it's judgement due to our sins. But now we are forgiven in Christ so it is not needed. So it's authority and power has been taken away; spoiled.
Let therefore, because of everything that was just said. Let no man judge you either in meat and drink offerings, holy days, new moon celebrations and Sabbaths in which were also written in the handwriting of ordinances that dealt with when we sinned. For it's power has been spoiled, stripped away, for we have been forgiven through Christ and the things they symbolize are but a shadow of things to come but the Body is Christ which we are now complete in. Please take note they are to come. So the stance that Christ is now are Sabbath is also debunked here.
Col 2:7 Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
Col 2:9 For in him dwelleth all the fulness of the Godhead bodily.
Col 2:10 And ye are complete in him, which is the head of all principality and power:
Col 2:11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
Col 2:12 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
Col 2:13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Col 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
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:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
