Is this talking about rules or human standards?
In col 2:13-15 it says 13When you were dead in your sins and in the uncircumcision of your sinful nature,[b] God made you[c] alive with Christ. He forgave us all our sins, 14having canceled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross. 15And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.[d]
Then he goes on telling the colossians not to let anyone judge them by "what they dont do!" which goes to mean to me is that the colossian church still has rituals and human imposed rules and regulation to work out their relationship with God ..
18Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions.
and this is your question : 20Since you died with Christ to the basic principles of this world, why, as though you still belonged to it, do you submit to its rules: 21"Do not handle! Do not taste! Do not touch!"? 22These are all destined to perish with use, because they are based on human commands and teachings. 23Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and their harsh treatment of the body, but they lack any value in restraining sensual indulgence.
I like the NLT version 22 Such rules are mere human teachings about things that deteriorate as we use them. 23 These rules may seem wise because they require strong devotion, pious self-denial, and severe bodily discipline. But they provide no help in conquering a person’s evil desires.
Paul was explaining GRACE... the colossian church (i guess the ones who are TRYING to follow the religious rules again) and Paul is saying dont TRY .. TRUST in the work of JESUS. Trying by using "self-imposed worship, their false humility and their harsh treatment of the body" will not make them any holier..
So my answer is both .. he was talking about the Religious Jewish Laws and Human Standards that is added to it..
personally i catch myself treating my body harshy by fasting or praying or TRYING so hard... but the answer is TRUST.
