Romans 14 says God doesn’t care which days are honored by a believer, so stop judging that.
Rom 14:4 Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Lord is able to make him stand.
Rom 14:5 One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind.
Rom 14:6 The one who observes the day, observes it in honor of the Lord. The one who eats, eats in honor of the Lord, since he gives thanks to God, while the one who abstains, abstains in honor of the Lord and gives thanks to God.
God says to stop judging others on the days the keep, the reason being there’s no command to keep any day in the two love commands that supersede the Decalogue.
As to Colossians 2:16-17
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 isof Christ.
The word sabbath above, is H4521 in Strongs, and it means ALL the sabbaths, especially the WEEKLY sabbath:
G4521 (Strong)
σάββατον
sabbaton
sab'-bat-on
Of Hebrew origin [H7676];
the Sabbath(that is, Shabbath), or day of WEEKLY repose from secular avocations (also the observance or institution itself); by extension a se'nnight, that is, the interval between two Sabbaths; likewise the plural in all the above applications: - SABBATH (DAY), week.
Total KJV occurrences: 68
All the types of the sabbath are shadows of Jesus, who is the substance that casts the shadow, especially the weekly sabbath..
So let no one judge us, says the passage, over the sabbath days, because they are but fore-shadows of the rest we have in Jesus now, no longer in a ceremonial shadow, but in Him.
That’s just too clear to obfuscate.
