Where does the Bible say "ceremonial law"?
Where does the Bible say Gentiles are the former covenant people?
Where in the Bible does it say Gentiles are under the ten commandments?
Where is it?
The bible clearly points to different laws
In both the old and new Testament.
The law is often described by context.
For example
Eph 2:15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
This law was abolished. Which law is it??
It isn't the one Jesus was referring to in Matt 5:17
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
The book of Hebrews is good at explaining the cerimonial laws.
Heb 8:4-5
4 For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law: 5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
MOSES was shown by God the pattern.
Moses was given laws as shadows of heavenly things.
Based on the biblical account in Revelation, the Ark of the Covenant—which historically contained the Ten Commandments—is described as being in the heavenly temple. This shows that the divine, moral law (the Ten Commandments) is preserved in heaven, representing God's unchanging standard.
Rev 11:19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
There are 2 laws because one is in place defining Sin today and one was abolished at the cross.
What we call those laws might differ but the thing that defines what makes the law void or not void is the purpose.
Some laws were a shadow of Christ and these were nailed to the cross.
Heb 10:1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
2:17 Which are a shadow of things to come; but the body is of Christ.
Heb 9:10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.
Carnal ordinances.
Gal 3:24-25
24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 25 But after that faith is come, we are no longer under a schoolmaster.
But you cannot deny that there has always been and will always be a law from start until the finish defining what sin is.
The ceremonial law was a "figure for the time then present" (Hebrews 9:9). Every lamb slain on an altar was a lesson teaching that "without shedding of blood is no remission" (Hebrews 9:22). These laws reached their "end" or goal in Christ, who is the true "Lamb of God" (John 1:29).
