There is a terrible misconception, or lie, that Paul at Colossians 2:16 is telling the gentiles do not let anyone judge them for not keeping kosher food laws, for not keeping the festivals of YHWH, and do not let them judge you for anything to do with the Sabbath day.
1st off, if you know your creator told you to keep all of that stuff, why would you believe Paul was worthy to be listened to if you thought he was saying ignore the Creator?
Paul here was talking to the new "converted" gentiles, the gentile nations were heavily pagan.
Paul was telling these new "converts" to not let anyone such as gentiles or pagans judge them for KEEPING Kosher food laws, festivals of YHWH, and the Sabbath day!
He was not saying don't let any person at all get onto you for disobeying the Law of YHWH, but that is what the false teachers today like to teach their listeners!
Take a look at the Scripture;
Colossians 2:16 "Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath"
Now lets look at the very next verse, the Greek document actually says a slightly different thing than some of the English translations, if there is italicized words, ignore them;
Colossians 2:17 "Which are a shadow of things to come, but the body of Messiah"
So Paul then says all of these commandments and festivals are a shadow of things to come!
Notice that they "are", as in currently and still are, not "was", as in in the past and not anymore.
Next, pay attention to the part that says "but the body of Messiah", when looking at the 2 verses together, they combine to say don't let anyone judge you except the body of Messiah.
So do not let the pagans/gentiles judge you, or anyone, but the body of Messiah judge you.
It's not actually saying don't let anyone judge you period, and actually teaches us to judge, and to expect judgment from the body of Messiah.
Colossians 2:16 "Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath, which are a shadow of things to come, but the body of Messiah"
