There is still the major flaw with your position that the Bible never lists which laws are ceremonial or moral laws, it never speaks against treating ceremonial laws are moral laws, and it never even refers to the categories of ceremonial or moral law. You should not interpret Isaiah as if he had in mind a division between two sets of laws that you created.
I think its were rightly dividing comes in, Of course it gives the difference between ceremonial laws as shadow and moral as judgeable damnable substance.
Violation to a ceremonial law can end up a one dead as a example to the flock.
Ceremonial laws are designed to draw in unbeliever world towards the living word of God. Not a outward sign to themselves,
Believers have prophecy no need for shadows used in parables .
For instance the baptism of one that has a desire to perform the will and become a member of the priesthood like Aaron's two sons .They added to it called "strange fire" self edification They were hoping it was 15 minutes of self-righteous fame . They were consumed, the ceremonial attire not a hint of smoke
Or the man who gathered firewood on the day they were to eat the manna as part of the ceremonial fast .He was stoned .
Number 15 :31-33 Because he hath despised the word of the Lord, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him. And while the children of Israel were in the wilderness,
they found a man that gathered sticks upon the sabbath day.And they that found him gathering sticks brought him unto Moses and Aaron, and unto all the congregation.
Or the young man named Eutychus, being fallen into a deep sleep: and as Paul was long preaching he fell out the window (
Acts 20:9 as a example.
If every time one did fall asleep during the preaching of the gospel was killed it would reduce the number of those that assemble together .
Turning ceremonial laws into oral tradition of dying mankind. shown in John 21 with Peter. Peter as a oral traditions went to town and started a lie that John would not die . Jesus said if every time he had to dispel the lies of the oral traditions of men we would need a bigger planet to hold the volumes upon volumes that could of been written
John 21:25 King James Version25 And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen
The whole time period when there was kings in Israel (the abomination of desolation). He use that as a parable not to follow after the oral traditions of men. The old testament shadows disappeared when the time of reformation came
Hebrew 9: 8 The Holy Ghost this
signifying, (using the temporal dying things seen to give us the hidden gospel understanding) that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing: Which was a
figure (parable) for
the time then present, in which were offered both gifts and sacrifices, that
could not make him that did the service perfect, as pertaining to the conscience;
Which
stood only in meats and drinks, and divers washings, and
carnal ordinances, imposed on them until the
time of reformation.
One new ceremonial law a shadow was given Corinthian 11. (headship parable) That ceremonial shadow to the unbelieving world It will become substance when believers receive their new incorruptible bodies
