The shadows are what the Bible says they are....
what Jesus came to end. Dan9:27 not God's commandments, written by God, spoken by God- God's own Testimony Exo31:18 in God's ark in heaven Rev11:19 that God's saints through love Exo20:6 keep until the very end Rev14:12 Rev22:14
Heb 10:1
For the law, having a shadow of the good things to come,
and not the very image of the things, can never with
these same sacrifices, which they offer continually year by year, make those who approach perfect. 2 For then would they not have ceased to be offered? For the worshipers, once [
a]purified, would have had no more consciousness of sins. 3 But
in those sacrifices there is a reminder of sins every year. 4 For
it is not possibl
e that the blood of bulls and goats could take away sins.
5
Therefore, when He came into the world, He said:
“Sacrifice and offering You did not desire,
But a body You have prepared for Me.
6
In burnt offerings and sacrifices for sin
You had no pleasure.
7 Then I said, ‘Behold, I have come—
In the volume of the book it is written of Me—
To do Your will, O God.’ ”
8 Previously saying,
“Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them” (which are offered according to the law), 9 then He said, “Behold, I have come to do Your will, [
b]O God.” He takes away the first that He may establish the second. 10 By that will we have been [
c]sanctified through the offering of the body of Jesus Christ once
for all.
The weekly Sabbath came before sin, before the fall, before one animal sacrifice and was never a shadow of Christ, but points to Him as our Creator Exo20:11 the only God we are to worship Rev14:7 and continues Isa 66:23 thus saith the LORD.
If one wishes to force Paul to teach against Christ, when Paul said everything had to be according to Him and teach that spending sanctified time honoring our LORD, God's blessing, Gods sanctification, the day that our Savior Jesus Christ is LORD of, the Sabbath day, is against man, when He said the Sabbath was made for man, that will have to be between those who teach this and God. Its certainly not what Paul believed or taught, Paul faithfully remembered the Sabbath day and kept every Sabbath holy decades and decades after the Cross Acts 13:42 Acts 13:44 Acts 15:21 Acts 16:13 Acts 17:2 Acts 18:4 just as Jesus said His faithful would Isa 56:6-7 Mat24:20. Paul was a servant of God Rom1:1 and servant is not greater than their master John13:16 and a servant serves the LORD the way He asks Isa 56:6, otherwise its not really serving, it saying we know better, something Paul warned about Rom6:16KJV
