There is no way for Christian theology to skate around the facts of Colossians 2:16-17
The plain text makes it totally clear the Sabbath is the substance of Christ.
The plain text makes it totally clear the Feasts are the substance of Christ.
The plain text makes it totally clear the New Moons are the substance of Christ.
The plain text makes it totally clear the Leviticus dietary law is the substance of Christ.
Colossians 2:16-17 So let no one judge you in food or in drink, or regarding a festival or a new moon or Sabbaths, 17 which are a shadow of things to come, but the substance is of Christ.
And in the plain text, those things are called a shadow of things to come, meaning they are a shadow of something that is coming in the future!
What is “things to come”?
In all the rest of the Bible through Revelation, THE THING that is coming is the New Jerusalem.
The New Jerusalem comes AFTER The Judgment where sinners not covered by Messiah’s blood pay for their sins.
One sure way to not be covered by Messiah’s Blood is to reject keeping his Father’s Sabbath, Feasts, New Moons, and Dietary LAWs.
There is no sacrifice for intentional sin(s).
In Colossians, Paul is talking to Sabbath keepers, Feast keepers, New Moon observers, and CLEAN food eaters… They are Torah keepers just like God’s Son.
The Sabbath is the Substance of God’s Son!
