But New Testatment scriptures do not "trump" the Old Testament scriptures. Islam has to cast doubt on both the Old and New Testament scriptures as having been corrupted in order to get the Koran accepted. Christianity never casts doubt on the Old Testament and holds it to be fully the Word of God. Jesus said that he didn't come to destroy the law but to fulfill it.
First, the Old Testament is very clear that the dietary laws applied only to Israel and were part of a covenant between Israel and God. The Old Testament gives the reason for the dietary laws were to separate Israel from other nations. They never applied to anyone other than Israel. Therefore all Gentiles are automatically exempt from the dietary laws because they are not part of the Mt. Sinai covenant.
Second, the same Old Testament that gave the dietary laws specifically to Israel for specific reasons, also spoke about a "New Covenant". That "New Covenant" which is Christianity casts off those dietary laws as a symbol that salvation is offered to all people unlike the Israeli covenant that was only between Israel and God. And since the New Covenant was prophesized by the Old Testament, the new covenant can hardly be considered to be inconsistent or trumping the old, but rather is a fulfillment of the Old.
Jeremiah 31:31
31:31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah;
Frist of all, is this "new covenant" made with the Christian Gentile Church or with the descendants of the Tribes of Jacob of the House of Judah and Ephraim (comprising the Ten Northern Tribes of Jacob)?
Let's say that you, as the Christian, are Ephraim and this prophecy applies to the Christian Church, then according to the timing of when God will make this "new covenant", can you say that this "New Covenant" is already made and existing because the Christians have been restored to the land of Israel and their ancestor's faith? Or does most of Christianity today lay outside the land of Israel and have a belief system quite opposite to the Jewish Church of Jerusalem?
Notice that this "new covenant" is not made with the Gentiles; neither is it made solely with the house of Judah, the Jews. Rather, it is a future promise that is guaranteed to the Jews and to their brothers, the descendants of Joseph/Ephraim (J*sus called these the "lost sheep of the House of Israel [Ephraim])
Was God talking through Jeremiah the Prophet to Baptists, Methodists, Catholics today, or was God speaking through Jeremiah to the House of Judah (Jews of the Tribe of Judah and Benjamin) and the House of Israel (consisting of the Ten other Tribes of Jacob)?
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
God doesn't lie.
Could these promises be taken away from the physical descendants of Jacob/Israel and given instead to a group of Gentiles calling themselves "Christians" who reject the Laws of God let alone His appointed times such as Biblical Festivals and Sabbaths?
Are you grafted into Israel as Paul stated in Romans, or are you grated into a Gentile organization built upon Replacement Theology given to you by the early Gentile Catholic Church?
Also notice that the verse says 'I will put my law in their inward parts'. The law is STILL there!
Do you observe the Festivals and Sabbaths of the Lord and of Israel, or do you observe pagan holidays that have had J*sus' name affixed to them and have taken the place of what is commanded in Scripture (the Torah)?
Have you substituted the "day of the sun" (Sunday) for the Sabbath?
Are you the "remnant" among the Gentile nations who will be gathered as the "elect" and be presented at the Marriage Supper along with Judah-Benjamin, thus making up the Bride of Messiah, or will you be delegated to be the "servant-foolish bride" and be cast out of the Wedding Supper because J*sus, a Jew, in his own Torah, is commanded by his Father to not marry Gentiles! The only Gentile who will become a bride to Messiah is one, like Ruth, who said "your people will be my people and your God my God."
Is the "New Covenant" really NEW at all?
covenant from the Hebrew

testament and covenant both bring up 1242 from the Greek

1) a disposition, arrangement, of any sort, which one wishes to be valid, the last disposition which one makes of his earthly possessions after his death, a testament or will
2) a compact, a covenant, a testament

Notice it does NOT say the church!
Do the actual words in the Greek Scriptures show us that a "testament" is made between God and the Church? NOPE!
It does mention the covenant with Noah though.....
Gentiles are under the covenant of Noah (Genesis 9).
Hebrews 8
10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
Hebrews 8:10 says: "For THIS the covenant," and then quotes from Jer. 31:33.
Hebrews 8
10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
this from the Greek
3778 houtos hoo'-tos, including nominative masculine plural houtoi hoo'-toy, nominative feminine singular haute how'-tay, and nominative feminine plural hautai how'-tahee from the article 3588 and 846; the he (she or it), i.e. this or that (often with article repeated):--he (it was that), hereof, it, she, such as, the same, these, they, this (man, same, woman), which, who.
1) this, these, etc.
846 autos ow-tos' from the particle au (perhaps akin to the base of 109 through the idea of a baffling wind) (backward); the reflexive pronoun self, used (alone or in the comparative 1438) of the third person , and (with the proper personal pronoun) of the other persons:--her, it(-self), one, the other, (mine) own, said, (self-), the) same, ((him-, my-, thy- )self, (your-)selves, she, that, their(-s), them(-selves), there(-at, - by, -in, -into, -of, -on, -with), they, (these) things, this (man), those, together, very, which.
1) himself, herself, themselves, itself
2) he, she, it
3) the same
In other words, "this---same" covenant, as was spoken by Jeremiah has now been RENEWED .... NOT REPLACED! THE SAME COVENANT, WITH ITS LAWS AND COMMANDMENTS WHICH ARE ITS COVENANT STIPULATIONS.
How do Gentiles, who once were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, who had no hope, and were without God in the world according to Eph. 2:12 become part of this "New/Same Covenant" of Jeremiah spoken about in the New Testament? By being grafted into Israel and the faith of Israel which practices Sabbaths and Festivals, or by becoming members of various denominations and non-denominations which reject God's Biblical Feasts, Festivals, and Sabbaths?
Are you "in the faith" or just have "a" faith about something which God never gave mankind?
Jeremiah 31 states that the day will come when this "RENEWED" covenant will be made with "whom"? Israel and Judah? Or with Judah and the church which rejects the faith of Judah?
The answer to that question is "Israel and Judah".
Israel being understood as Ephraim who today are dispersed Gentiles worldwide to whom can be traced Jewish Roots all the way back to the Assyrian Captivity and whom reject paganism and paganized religious practices, the very reason Ephraim was taken captive in the first place. They strayed from the faith of their fathers.
