One that dismisses the commandments is not a member of the Body:
Collossians 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:
[17] Which are a shadow of things to come; but the body of Christ.
Let us know when you join the body, and quit your iniquity!
Galatians 2:14 When I saw that they were not acting in line with the truth of the gospel, I said to Cephas in front of them all, You are a Jew, yet you live like a Gentile and not like a Jew. How is it, then, that you force Gentiles to follow Jewish customs?15 We who are Jews by birth and not sinful Gentiles 16 know that a person is not justified by the works of the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by the works of the law, because by the works of the law no one will be justified.
17 But if, in seeking to be justified in Christ, we Jews find ourselves also among the sinners, doesnt that mean that Christ promotes sin? Absolutely not! 18 If I rebuild what I destroyed, then I really would be a lawbreaker.
19For through the law I died to the law so that I might live for God. 20 I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me. 21 I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!
Galatians 3:23 Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed. 24 So the law was our guardian until Christ came that we might be justified by faith. 25 Now that this faith has come, we are no longer under a guardian.
Galatians 4:10 You are observing special days and months and seasons and years! 11 I fear for you, that somehow I have wasted my efforts on you.
As for your fidelity to the false teacher, Michael Rood: Gal 4:17 Those people are zealous to win you over, but for no good. What they want is to alienate you from us, so that you may have zeal for them.
