Knowing this, I just don't see how Colossians 2 can be about the seventh day Sabbath, when all that is mentioned is food and drink and that is more inline with the Sabbath(s) festivals,
Num 28:1 The LORD spoke to Moses, saying,
Num 28:2 “Command the people of Israel and say to them, ‘My offering, my food for my food offerings, my pleasing aroma, you shall be careful to offer to me at its appointed time.’
Num 28:3 And you shall say to them, This is the food offering that you shall offer to the LORD: two male lambs a year old without blemish, day by day, as a regular offering.
Num 28:4 The one lamb you shall offer in the morning, and the other lamb you shall offer at twilight;
Num 28:5 also a tenth of an ephah of fine flour for a grain offering, mixed with a quarter of a hin of beaten oil.
Num 28:6 It is a regular burnt offering, which was ordained at Mount Sinai for a pleasing aroma, a food offering to the LORD.
Num 28:7 Its drink offering shall be a quarter of a hin for each lamb. In the Holy Place you shall pour out a drink offering of strong drink to the LORD.
Num 28:8 The other lamb you shall offer at twilight. Like the grain offering of the morning, and like its drink offering, you shall offer it as a food offering, with a pleasing aroma to the LORD.
Sabbath Offerings
Num 28:9 “On the Sabbath day, two male lambs a year old without blemish, and two tenths of an ephah of fine flour for a grain offering, mixed with oil, and its drink offering:
Num 28:10 this is the burnt offering of every Sabbath, besides the regular burnt offering and its drink offering.
A. The Sabbath was an appointed time.
B. The Sabbath was a sign with Israel.
C. The Sabbath had associated food and drink offerings.
not God's holy weekly Sabbath that started from creation Genesis 2:3
The yearly appointed times were "holy" as well:
Lev 23:4 “These are the appointed feasts of the LORD, the holy convocations, which you shall proclaim at the time appointed for them.
We already looked and found no mention of humans keeping Sabbath before Exodus 16.
God spoke the fourth commandment at Sinai. Exodus and Genesis both quote those words.
In Genesis we see God resting from His work of creation. And in Exodus 20 we see God indicating that He also wants Israel to rest to remember that He is their Creator. And in Deut. 5 He wants them to remember He is their Savior from Egypt.
He gives them a sign to remember who they are making the covenant with.
and will be eternal on the New Earth Isaiah 66:23.
That whole section is fascinating, and we can look at it in greater detail after Colossians 2 if you like.
However, suffice to say for now,
a. Why wouldn't it be in the new earth? In Acts 21 Jewish believers are still keeping all the law.
b. it also mentions the new moon, which the Jewish believers would also be keeping, but Colossians 2 calls a shadow.
Do you do any assembling on the new moon? A few Adventists do. Most don't.
I don't think Paul is speaking about the seventh day Sabbath either regarding when he says don't esteem one day above the other and goes on to say the only thing that really matters is keeping God's commandments, which includes the 4th.
Was circumcision in the flesh a commandment of God? Was the Day of Atonement a commandment of God?
The commandments God gives us we should keep. However, He does not require all in the new covenant of Gentile believers. Acts 15 states that.
If you want to keep them all, become messianic. If you see in Scripture that some are not now required for Gentiles in the new covenant (and arguably anyone in the new covenant), then you have to look at texts that indicate that could include the Sabbath.
And the scope of Romans 14 is very broad. One person considers all days the same, and doesn't observe. Yet that is still to the Lord.
Jesus said Sabbath was made for us (man) Mathew 2:27. I just can't come up with the same conclusion as you do when it comes to the 4th commandment, God's holy Sabbath day.
I would also like to go through this text after the other two. Perhaps you have a longer attention span than LGW thinks others here do.
