So, if I follow your OP correctly, then, you say that the Food and Drink Cerimonial Laws are God's Commandments and should be kept?
As well as the Saturday Sabbath?
Yeah we are to keep Gods sabbath day and all His commandments. As for the food and drink laws spoken of in Col.2 we should let scripture interpret scripture
COL. 2 [16] Let 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:
Lets look at scripture that talks about the same thing as Col.2
EZEKIEL 45 [17] And it shall be the prince's part to give burnt offerings, and MEAT offerings, and DRINK offerings, in the FEASTS, and in the NEW MOONS, and in the SABBATHS, in all solemnities of the house of Israel: he shall prepare the sin offering, and the meat offering, and the burnt offering, and the peace offerings, to make reconciliation for the house of Israel.
Heres one. Same exact order as Col.2{16}, meat, drink, holy days (feast days), new moons, sabbaths. What are the odds these 2 scriptures are not speaking about the same thing? A trillion to one? Do you believe that Ezek.45 is telling the old testament folks they no longer need keep Gods sabbath day or that its alright to go out and eat their piggys? Aint no way. 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. The many claim that the meat and drink spoken of in Col.2 are the unclean foods such as the oinker. 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.
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.
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.
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.
When we let scripture interpret scripture its very clear what Col.2 is speaking about. The meat and drink offerings of those days are no longer to be kept.
