What does that matter? Your argument was that I can't partake of the festivals because sacrifices were done on those days. The sameholds true for the Sabbath. In reality, sacrifices were done every day so I guess we can't partake of any day based on your logic.
The handwriting of ordinances does not refer to the law of Moses. It refers to man made laws. The Greek word for ordinances here is a form of the root word "dogma" which means man-made rules, laws, commandments, precepts, etc. Paul is not talking about YHWH's ordinances or Moses' ordinances in this verse. He is talking about man's ordinances or traditions. This same word is used in Colossians 2:20 pertaining to the doctrines and commandments of men; in Luke 2:1 pertaining to a decree from Caesar Augustus; in Acts 17:7 pertaining to a decree from Caesar; and in Ephesians 2:15 concerning the ordinances of men. It always pertains to man's commandments, not YHWH's. Compare the word dogma with the Greek word that pertains to YHWH's ordinances, "dikaioma."
This word dikaioma was used in Luke 1:6 pertaining to the ordinances of YHWH and in Hebrews 9:1,10 pertaining once again to YHWH's ordinances. Therefore, Paul is saying in Colossians 2:14 that the traditions and commandments of men are the issue, not YHWH's laws. But what was nailed to the cross? The Greek construction shows that the "handwriting" was nailed, not the ordinances. The handwriting or, in Greek, the "cheirographon" was a certificate of debt. Whenever a man sins against YHWH his sin is imputed against him (Romans 4:7,8). When men exalt the traditions of men over the commandments of YHWH, as the Pharisees did, for example, they sin against YHWH. The Messiah became sin for us and when he was nailed to the tree so were the sins that were imputed against us. YHWH's holy ordinances were not nailed to the tree, the certificate of debt resulting in our death sentence was nailed to the tree. That is why Paul said the Colossians were "dead in your sins" in verse 13. The principalities and powers of verse 15 caused the people to sin by their man-made laws but Messiah was victorious over them.
