Sounds like more SDA propaganda.
Again, Ad hominem, and may be safely ignored.
An unbiased reading of Colossians 2:16 will show that this is talking about not just "ceremonial Sabbaths."
Let's look then shall we, unbiasedly?
Context, Colossians 2:14, "ordinances", not God's Law.
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:
The order is given as:
[1]
"daily" [in meat, or in drink [offerings]],
[2]
"seasonally" [or in respect of an holyday; ie feast days of seasons, Spring, Fall]
[3]
"monthly" [of the new moon]
[4]
"annually, yearly, and 7th year and 50th Year" ["of the sabbath [days]" [plural]].
Paul is citing, several passages in Colossians 2. in this instance, He is citing, Ezekiel 45:17. The order of progression is specific.
Eze 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.
Colossians 2 KJB, parallels Ephesians 2 KJB, and Hebrews 9-10 KJB.
The language is the same.
The "ordinances" in Colossians 2 deals with "shadows", such as the daily "meat and drink" offerings of a worldly sanctuary and carnal ordinances, the seasonal "feast days", the monthly "new moons", and the year based "sabbaths", in the singular, every 7 and 50th years, as Paul is citing Psalms 98:1-3; and Ezekiel 45:17 KJB with other texts.
The Sabbath of the LORD thy God is always called "my [as in God's] sabbaths", and the others in Leviticus 23:4 onward are called "your [the peoples] sabbaths" [Leviticus 26:35 KJB] which are "beside [given in addition to] the sabbaths of the LORD" [Leviticus 23:38 KJB].
The Ten Commandments, including the Sabbath of the 4th Commandment, are "light" [Proverbs 6:23, Isaiah 8:20, 51:4 KJB],
never a
"shadow", are
"spiritual" [Romans 7:14 KJB],
never "carnal" [Hebrews 9:10 KJB], are
God's Law (Exodus 20:1-17),
never "ordinances" as Passover (Numbers 9:12) etc.
Colossians 2:14 - "ordinances"
Ephesians 2:15 - "law of commandments contained in ordinances"
Hebrews 9:1 - "ordinances of divine service"
Hebrews 9:10 - "
carnal ordinances"
Colossians 2:16 - "in meat, or in drink" [offerings]
Hebrews 9:10 - "meats and drinks" [offerings]
Colossians 2:12 - "also ye are risen with him"
Ephesians 2:6 - "raised us up together"
Colossians 2:16 - "a shadow of things to come"
Ephesians 2:7 - "in the ages to come"
Hebrews 9:11 - "of good things to come"
Hebrews 10:1 - "the law having a shadow of good things to come", "those sacrifices", "offered year by year"
[ps. none of the Ten Commandments deal with carnal sacrifices]
etc.
The text speaks of plural, "sabbath days" (or 'of sabbaths'). The context, is also not concerned with all 'sabbaths' but is limited in scope, to that which is "shadow" (not light, not body or substance), that which is "of things to come" (type pointing to the future events) and of "ordinances", as follows.
[1] The Sabbath of the LORD thy God, of Creation (Genesis 2:1-3; Exodus 20:8-11), was given to mankind (Adam) before the sin of mankind (Mark 2:27), before the need of shadow and type, which were given after the sin of mankind, under the Levitical priesthood.
[2] The Sabbath of the LORD the God, is a memorial (pointing backwards, thu the words "Remember" (Exodus 20:8)), to a perfect world without sin, perfect relationship, perfect rest), and is not pointing to the future.
[3] The Sabbath of the LORD thy God, is singular and specific. "The seventh day" "the sabbath" "of the LORD thy God".
Exodus 20:8 KJB - Remember
the sabbath day, to keep it holy.
Exodus 20:9 KJB - Six days shalt thou labour, and do all thy work:
Exodus 20:10 KJB - But
the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exodus 20:11 KJB - For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested
the seventh day: wherefore the LORD blessed
the sabbath day, and hallowed it.

[4] The Sabbath of the LORD is separate from the yearly festal sabbaths, as denoted in Leviticus 23 (see Leviticus 23:3; then see Leviticus 23:4,38 "beside the sabbaths of the LORD")
[5] The Sabbath of the LORD thy God, is called "the sabbath of the LORD" (Exodus 20:8-11, etc), and "My sabbaths" (Isaiah 56:4; Ezekiel 20:20), as opposed to theirs, called "your sabbaths" (Leviticus 26:34,35), and "her sabbaths" (Leviticus 26:34,43; 2 Chronicles 26:31; Lamentations 1:7; Hosea 2:11), etc.
[6] Colossians 2, in its entire context says nothing about "the seventh day", but speaks of merely the shadow sabbaths (plural, not singular), and says nothing of "commandment" (as Luke 23:54,56 does), but speaks of wordly "ordinances" (Colossians 2:14,20).
[7] Colossians 2, speaks of "sins" (Colossian 2:13), which is "transgression of the law" (1 John 3:4), of which the 4th Commandment (Exodus 20:8-11) is central, whereas the yearly (and of years) sabbaths are not given in the Ten Commandments at all
More can be said, but 7 was a good number to round it off at this point, more in detail in a bit.
(PS there is no such thing as "the LXX", and is actually by Origen and another. Evidence upon request.)
