Colossians 2:16-20 (Amplified Bible)16Therefore let no one sit in judgment on you in matters of food and drink, or with regard to a feast day or a New Moon or a Sabbath. 17Such [things] are only the shadow of things that are to come, and they have only a symbolic value. But the reality (the substance, the solid fact of what is foreshadowed, the body of it) belongs to Christ. 18Let no one defraud you by acting as an umpire and declaring you unworthy and disqualifying you for the prize, insisting on self-abasement and worship of angels, taking his stand on visions [he claims] he has seen, vainly puffed up by his sensuous notions and inflated by his unspiritual thoughts and fleshly conceit, 19And not holding fast to the Head, from Whom the entire body, supplied and knit together by means of its joints and ligaments, grows with a growth that is from God. 20If then you have died with Christ to material ways of looking at things and have escaped from the world's crude and elemental notions and teachings of externalism, why do you live as if you still belong to the world? [Why do you submit to rules and regulations?--such as]1. Observance of the law produces spiritual death2. The law contains shadows and typology whose primary purpose as many have already commented and the bible clearly states is a school master that brings us to Christ and as the bible says "we are no longer under the school master".
Today the Sabbath is not Saturday, Sunday or Tuesday or Thursday. It is everyday. 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: Notice he says sabbath days (plural). There were 3 different sabbath days in the OT.
Legalism kills, the Spirit of the Sabbath gives life, and He is Lord of the Sabbath. Not just one day but every day.He is our Sabbath.In Christ: Phillip
