Yes, the GOK is no longer valid for today.
But it was valid during the time of the 4 gospels, just like circumcision was valid in ages past too.
Once the new covenant was ushered in the old was abolished forever. Colossians 2:14 plainly declares, speaking of these Old Testament ordinances and what happened at Calvary:
“Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross.”
The Greek word for “blotting out” here is
exaleiphō meaning: ‘to wipe off, wipe away, to obliterate, erase, wipe out, blot out’
Q. When did/will the “blotting out the handwriting of ordinances” occur?
A. Christ “took it out of the way” by “nailing it to his cross.”
These ordinances embraced the old covenant civil, ceremonial and ecclesiastical law. They were finished at the cross. When Christ made that final sacrifice for sin, He satisfied all God’s holy demands for sin and uncleanness and thus He became the final propitiation and substitution for the sinner.
Colossians 2:16-17 continues, keeping on the same theme:
“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: Which are a shadow of things to come; but the body is of Christ.”
The Greek word translated “holyday” here is
heorte meaning a festival or feast. The KJV should probably have used “feast” or “festival” here rather than holyday because out of 27 mentions of this word in the New Testament it is interpreted “feast” in all of them apart from here.
New American Standard puts it like this: “Therefore let no one act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day -- things which are a mere shadow of what is to come; but the substance belongs to Christ.”
The Living Bible says, “So don't let anyone criticize you for what you eat or drink, or for not celebrating Jewish holidays and feasts or new moon ceremonies or Sabbaths. For these were only temporary rules that ended when Christ came. They were only shadows of the real thing-of Christ himself.”
Paul is saying here that the old covenant feasts and festivals simply served as types and shadows of things that were to come. They looked forward to the new covenant arrangement and the reality and substance in Christ. The old covenant Jews didn’t have a full revelation of this new system. Premillennialism should take note of the forward-looking nature of the old covenant sacrifices. This disallows a revival of this abolished system in some supposed future millennium after the second coming.
Paul ties up his reasoning in Colossians 2:20-22, summing up the new covenant freedom: “Wherefore if ye be dead with Christ from the rudiments of the world, why … are ye subject to ordinances, (Touch not; taste not; handle not; Which all are to perish with the using) after the commandments and doctrines of men?”
The phrase “are ye subject to ordinances” is interpreted from the lone Greek word
dogmatizo, which literally means to submit to ceremonial rule. Christianity took us completely away from the bondage of the old Mosaic ceremonial law. These festivals were filled with numerous ordinances and blood sacrifices that had to be stringently observed. Speaking of these impotent religious ordinances, Scriptures counsels: “Touch not; taste not; handle not.”
