Nice try, but legalism and "judaizing" are false gospel messages (false or aberrant doctrine). The gospel is embodied in John 3:16. Believe in Jesus and be saved. The false gospel of legalism and Judaizing (often taught in christian cults) blurs the distinctions between the Old covenant of law and the new covenant of Grace. An example of this would be the assertion that we must believe in Jesus, obey the Sabbath and only eat kosher foods to be saved or approved by God.
I have eaten Kosher foods. I have attended Passover Seders. I have a mezuza on my door. However, I have done these things as purely elective and not out of a sense compulsion to law. So if you elect to observe the Sabbath that is fine, but if you are doing it because you believe it is law then you have been severed from Christ.
My original comment was not about observing the sabbath. It was about how Matt seems to only post on the sabbath, defending the sabbath observance, etc and rarely seems to mention Jesus. Where on focuses is where one's treasure is, right? Was I judging or showing concern?
Colosians 2:16 does not apply to me or others who warn or argue with those who claim the sabbath is law. Col. 2:16 is about freedom from the law. If you claim that I must keep parts of the old covenant and new covenant. It is adding new wine to old wine skins. The wine skins will burst and the wine becomes wasted on the ground.
