Thank you!
In Col 2:16 if you look at the context it is referring to food, drink holy days and sabbath(s) and it is what was contained in
ordinances handwritten by Moses.
This is referring to the annual feasts days, also called sabbath(s) and holy day(s) all written by Moses as ordinances in the law of Moses- nothing to do with the Ten Commandments and the feast days which included animal sacrifices all pointed forward to Jesus who because our Sacrificial Lamb. So instead of sacrificing animals for sin (breaking God's law) we can go directly to Jesus when we have a change of heart and direction and repent of our sins. The blood of animals made nothing perfect Heb 10:4 the blood of Christ is perfect for cleansing us of all sin and unrighteousness.
Col 2:17
which are a shadow of things to come,
but the substance is of Christ.
And what it pointed forward to
Hebrews 10:1
For the law, having a shadow of the good things to come,
and not the very image of the things,
can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. 2 For then would they not have ceased to be offered? For the worshipers, once purified, would have had no more consciousness of sins. 3
But in those sacrifices there is a reminder of sins every year. 4 For it is not possible that the blood of bulls and goats could take away sins.

Therefore, when He came into the world, He said:
“Sacrifice and offering You did not desire,
But a body You have prepared for Me.
6 In burnt offerings and
sacrifices for sin
You had no pleasure.
7 Then I said, ‘Behold, I have come—
In the volume of the book it is written of Me—
To do Your will, O God.’ ”
8 Previously saying, “Sacrifice and offering, burnt offerings, and
offerings for sin You did not desire, nor had pleasure
in them” (which are offered according to the law), 9 then He said, “Behold, I have come to do Your will, [
b]O God.” He takes away the first that He may establish the second. 10 By that will we have been [
c]sanctified through the offering of the body of Jesus Christ once
for all.
11 And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. 12 But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, 13 from that time waiting till His enemies are made His footstool. 14 For by one offering He has perfected forever those who are being [
d]sanctified.
15 But the Holy Spirit also witnesses to us; for after He had said before,
16 “This
is the covenant that I will make with them after those days, says the Lord:
I will put My laws into their hearts, and in their minds I will write them,” 17
then He adds, “Their sins and their lawless deeds I will remember no more.” 18 Now where there is remission of these,
there is no longer an offering for sin.
Sin hasn't changed from the OC to the NC it is still the transgression of God's law the Ten Commandments Romans 7:7 Mat 5:19-30 but what changed was how we go about the forgiveness of sins. The Ten Commandments just show us our sins like a mirror Romans 7:7 Romans 3:20 and points us to Jesus who can cleanse us of all sin and unrighteousness when we confess so we can receive His mercy, grace and sanctification.
