(Also, see my post #3, especially my commentary on Col 2:13-14, which presents for you sabbath-keepers no small theological problem of just how many or our sins could Christ have forgiven in that passage if the entire Mosiac "written code" of law was not cancelled and nailed to his cross?)
First of all - you have Col 2:13-15 wrong.
Secondly gentiles were never charged with "sin" for failing to keep one of the ceremonial laws or one of the civil laws of the nation of Israel... it is only the moral laws of the TEN and of similar commandments that are condemning gentiles as sinners. This is a "basic" teaching for Rom 3, Rom 7 etc.
Acts 15 makes it clear for example that the law of circumcision which had never been applied to gentiles in the OT could not simply be "made up for gentiles" ad hoc in the NT by zealous Jewish Christians. (Notice that not even non-Christian Jews were doing that in the case of gentiles).
read 1 Cor 7:19
19 Circumcision is nothing, and uncircumcision is nothing, but
what matters is the
keeping of the commandments of God
The Commandments of God are contrasted to circumcision - making it very clear that they are not "one and the same" as some suppose.
so then in the commandments of God
"Honor your father and mother" is the first commandment with a promise - Eph 6:2
In the Commandments of God - the Law of Moses listed in James 2, in Rom 13, in Rom 7, in Matt 19, in Mark 7 etc is most certainly included
Deut 5:22 says "
God spoke these TEN words from the cloud... and added NO more"
- showing that the TEN are always included in what is termed "The Commandents of God" no matter what else from scripture is also included.
========================
As for Col 2
13 And when you were dead in your wrongdoings and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our wrongdoings, 14 having
canceled the certificate of debt consisting of
decrees against us, which was hostile to us; and He has taken it out of the way, having nailed it to the cross. 15 When He had disarmed the rulers and authorities, He made a public display
of them, having triumphed over them through Him.
"
Love God with all your heart" Deut 6:5 (and also Matt 22) - is not a "decree against us"
"
Honor your father and mother" Ex 20:12, Eph 6:2, Matt 19, Rom 13 .... is not "a decree against us"
"
the Sabbath was made FOR mankind" Mark 2:27 - ... is not "a decree against us"
When you drive down the road and see a 55 MPH speed limit sign -- it is not there "as a decree against you".
But
the TICKET that you get for speeding
IS a "decree against you" when you are found guilty.
In Col 2 -- IT is the debt owed, the condemnation as a law-breaker that is nailed to the cross... but "
Do not take God's name in vain" is not deleted by Christ as he points out in Matt 5. Christ pays our debt of sin - rather than "deleting His Word".. Not sure why this detail is so confusing for a few Christians.
