Its simply speaking of the meat and drink offerings which were written in the law contained within the ordinances which were to take place on Gods holy days, new moons and His sabbath days.
"Simply speaking...?"
Nowhere does scripture "simply speak" of the religious practice which pre-figures the death of Christ.
It was the God-given means of reconciliation and remission...until the establishment of the New Covenant.
The many claim that the meat and drink spoken of in Col.2 are the unclean foods such as the oinker.
It is good to know that we have not been left to wonder about this:
Acts 15:19-20 (King James Version)
19Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
20But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
Nor at we left at the misguided efforts of those who would seek to do that which is spoken against in many places in scripture:
Acts 15:10 (King James Version)
10Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
See that in it's context
here.
This is another gospel that seeks to lead men away from faith in Christ and to enslave them to the law, which was meant to lead men to Christ by showing them their sin.
Their ability to keep the law was as effective as it is today...they cannot.
Without the indwelling Spirit of God they are incapable of not only keeping the commandments of God, but are deceived into thinking that they do, and that they do so in the manner in which is necessary in order to be declared righteous before God...perfectly.
But, the good news for those who would trust in Christ, and believe that He died for their sin, is that He will give you the ability to keep His word:
Ezekiel 36:27 (King James Version)
27And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
Praise be to God for His Gift to sinful man.
If that were so please show me where any drink was said to be unclean. If there is an unclean drink ive yet to find it in the scriptures.
That Judaism had a concern for drink apart from that which is found in the "ceremonial law" can be seen here:
Matthew 23:24 (King James Version)
24Ye blind guides, which strain at a gnat, and swallow a camel.
Go and learn what that meaneth.
HEBREWS 13 [9] Be not carried about with divers and strange doctrines. For it is a good thing that the heart be ESTABLISHED WITH GRACE; NOT WITH MEATS, which have not profited them that have been occupied therein. [10] We have an altar, whereof they have no right to eat which serve the tabernacle. [11] For THE BODIES OF THOSE BEASTS, WHOSE BLOOD is brought into the sanctuary by the high priest for sin, are burned without the camp. [12] WHEREFORE JESUS ALSO, THAT HE MIGHT SANCTIFY THE PEOPLE WITH HIS OWN BLOOD, suffered without the gate.
What is found here in this passage is the contrast between the basic principles of Christ and the completion that Christ brought to those practices.
The heart is established with grace...not MEATS, as the OP has pointed out in clarity what the meaning is.
What is missed apparently is that those who were occupied therein, or, who's lifestyle was regulated by those things...
did not profit from them.
Why would one look past the Cross to return to those things?
Perhaps it is as this passage says, they are disqualified from the sacrifice of Christ, for, had they truly embraced Christ in faith, they would not seek to return to the basic principles of Christ, and go on unto perfection...the accomplished, once for all sacrifice for sin.
So why should we judge no man in meat or drink in respect to holy days, new moons and sabbath days? Because Jesus fulfilled these offerings that were written in the law of commandments contained in the ordinances. Its the meat and drink offerings that are no more to be observed.
But the question is, "Do believers today follow God's Law?"
The answer is yes...we establish the law of God, for His Spirit causes us to do that which we before were unable to accomplish.
What the Judaizer tries to establish is not the keeping of the law of God, but...the keeping of the law for salvation, which, scripture is clear is impossible.
Romans 3:20 (King James Version)
20Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Galatians 2:16 (King James Version)
16Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Failure to balance Old and New Testament revelation will inevitably lead to a misunderstanding of salvation.
JOHN 6 [53] Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. [54] Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. [55] For MY FLESH IS MEAT INDEED, and MY BLOOD IS DRINK INDEED.
To try to tie this to that referred to in Colossians 2:16 shows an utter disregard for the New Covenant, which has replaced the "first."
1 Corinthians 11:23-26 (King James Version)
23For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the same night in which he was betrayed took bread:
24And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
25After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
26For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Are we to replace this cup with the cup of Passover?
Will keeping the Passover, and the meat and drink contained therein change the fact that Christ is the reality, and Passover the shadow?
When we let scripture interpret scripture its very clear what Col.2 is speaking about.
Absolutely...
Colossians 2:16 (King James Version)
16Let 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:
...easy enough for a "child" to understand.
The meat and drink offerings of those days are no longer to be kept.
And the reason for that is that Christ has fulfilled that which they pre-figured.
To return to the ritual of Judaism is in fact a rejection of Christ, if it is done with the intent of "earning" salvation.
