Should Christians Keep the Feast Days?

Doug, doesn't explain what is so ceremonial about keeping the annual Sabbath as a holy day. A Sabbath is a Sabbath and they are all the commandments of God to keep.

There is nothing moral about disobeying the commandments and law of God to keep his holy Sabbaths of Lev. 23.
Deut 4:44 After stating the 10 commandments Moses says these very words! And this is the law which MOSES set before the children of Israel: Worse yet! The law says: Deu 8: 2 And thou shalt REMEMBER ALL the way which Jehovah thy God hath led thee these forty years in the wilderness,* that he might humble thee, to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments, or NOT"
Deut 31:24 And it came to pass, when Moses had made an end of writing the words of this law in a book, until they were finished,
25 That Moses commanded the Levites, which bare the ark of the covenant of the Lord, saying,
26 *Take this book of the law , and put it in the side of the ark of the covenant of the Lord your God, that it may be there for a WITNESS against thee.*
It's all one law, if you break the Sabbath of Lev. 23, you break the 10 commandments and the whole entire law! You are sinning because sin is the transgression of the law. (1John 3:4)
Exodus 12:49 *ONE LAW shall be to him that is homeborn, and unto the stranger that sojourneth among you.
The Lord of ALL the Sabbath days in the book of the law, then severely warns those who would dare say these holy days shouldn't be kept by saying these very words: Read them closely! Exodus 25: 20 Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared. 21 Beware of him, and OBEY his voice, PROVOKE him not; for he will NOT PARDON your transgressions (1John 3:4) for my name is in him. If you break ONE of them, you are guilty of the "the whole law" James 2:10.
it is written in Dan.7:25 And he shall speak great words against the most High, and shall wear out the saints of the most High, *and think to change (APPOINTED )times and LAW<

1John 3:4, Sin is the transgression of the law, not just the 10 commandments.

Instead of showing how moral the Sabbath is, the scriptures show that the sacrifices and circumcision are shown to take priority over the Sabbath keeping the Sabbath.
Matthew 12:5 Christ said, to the Sabbath keepers, "have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?
Thus showing that the animal sacrifices were more important to God, than Sabbath keeping. A total refutation of the Adventist visions and doctrine.
John 7:23 also declares the same thing! Showing that if the Sabbath was all that *"moral* the law would not have allowed circumcision of the flesh (which is a shadow) to overshadow the importance of resting on the Sabbath day! It was more important to perform the CEREMONY of cutting an innocent child's private parts and make him bleed on the Sabbath day, than to let it wait until Sundown.
Moreover, more animal sacrifices were offered on the Sabbath day than any other day, showing how ceremonial it was.
The weekly Sabbath was the most ceremonial of all the days of the week. NU 28! Then on the sabbath day two male lambs one year old without defect, and two-tenths of an ephah of fine flour mixed with oil as a grain offering, and its drink offering: 10‘This is the burnt offering of every sabbath in addition to the continual burnt offering and its drink offering. EZEK 46:45
And the burnt offering that the prince shall offer to the LORD in the sabbath day shall be 6 LAMBS without blemish, and a ram without blemish.!
Matthew 12:5
Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?

Deuteronomy 27:26 (KJV) 26  Cursed be he that confirmeth not all the words , of this law to do them. And all the people shall say, Amen.
Galatians 3:10 (KJV) 10  For as many as are of the works of the law are under the curse: for it is written, CURSED is EVERY ONE that continueth not in ALL THINGS  which are written in Book of the law to do them.  Mt. 5:17 says "the law and prophets" which means the entire book of the law and not one iota was going to pass from it! . So, you are guilty of breaking the Sabbath commandments of Lev. 23, all of them and the 10 commandments.
Duet 4:2 Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the Lord your God which I command you.
Exodus 12:49 *ONE LAW shall be to him that is homeborn, and unto the stranger that sojourneth among you.
The Lord of ALL the Sabbath days in the book of the law, then severely warns those who would dare say these holy days shouldn't be kept by saying these very words: Read them closely!Exodus 25: 20 Behold, I send an Angel before thee, to keep thee in the way, and to bring thee into the place which I have prepared. 21 Beware of him, and OBEY his voice, PROVOKE him not; for he will NOT PARDON your transgressions (1John 3:4) for my name is in him. If you break ONE of them, you are guilty of the "the whole law" James 2:10.
If you break ONE of them, you are guilty of the "the whole law" James 2:10.
So, either the Sabbath keepers do it all, or you are a transgressor of the whole law.
Mal.4:4 shows that the law of Moses is the law given at Mt Sinai (Horeb)> Not only that but Mal.4:4 starts with *"Remember" Mal4: 4 Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, even statutes and ordinances . The Adventist teach *forget the law of Moses"
