Ben, Paul did not insist that the Jewish Covenant be replaced with Christianity.
When he writes to the Gentiles, he urges them to not become circumcised because it is superfluous, in Christ, whether or not a Gentile be circimcised.
So Paul could be said to insist that Gentiles in Christ not become Jews.
"Could be said" is human conjecture. You are orthodox Reformed Christianity, nooc, on so many things of the NT, but on this point, you are
so unorthodox. . .
you have succumbed to a Jewish gloss, and are trying to have it both ways. . .grace for Gentiles, but law keeping for Jews. That is a dichotomized
false gospel,
against which Paul
emphatically warns, even
anathemizing (Gal 1:7-9).
God does not have two ways of salvation. . .one for Gentiles and another for Jews.
For Paul, the issue was
not about becoming Jews, it was about
requiring law-keeping for right standing with God.
But when he writes to Jews, he upholds the Law and their position in the Law and the continuing obligation that a Jew has to keep the Law whether he be a Christian Jew or not.
Which law is that? The
ceremonial laws, the
feasts, the cleansings? The Decaglogue?
Nooc, that is a completely unorthodox, gospel-eradicatng
misunderstanding of Rom, chp 9, and it
contradicts Rom, Chp 11.
Christians, whether Jew of Gentile, do
not have an obligation to keep the OT ceremonial laws, the feasts, or the cleansing laws.
Their obligation, as evidence of their
true saving faith, is only to the Decalogue and the commands of the NT (which include the Decalogue).
Paul insisted that
law keeping (circumcision) was
not required for right standing with God, as the
Judaizers were insisting. Not only was law-keeping not
required,
it was
contrary to grace, and
automatically excluded grace for right standing with God.
For the Judaizers, it may have been about becoming a Jew by circumsion, but for Paul it was a much bigger issue.
Circumcision was
really about
requiring law-
keeping for right standing with God, and on that there is
absolutely no compromise for anyone.
And then there is the
NT letter to the Hebrews, written to
Jews, which
completely overthrows the unorthodox dichotomy you present here.
Ro 9:30-32 -- "What then shall we say? That the (believing) Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but Israel,
who pursued a law of righteusness (to put God in one's debt), has not attained it. Why not? Because they pursue it not by faith but as if it were by works.
They stumbled over the 'stumbling stone.'
As it is written: 'See I lay in Zion a stone that causes men to stumble and a rock that makes them fall, and the one who trusts in him will never be put to shame.' "
Ro 11:1-10 -- "I ask then: did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. God did not reject his people, whom he foreknew. Don't you know what the Scripture says in the passage about Elijah--how he appealed to God against Israel: 'Lord, they have killed your prophets and torn down your altars; I am the only one left, and they are trying to kill me'? And what was God's answer to him? 'I have reserved for myself seven thousand who have not bowed the knee to Baal.' So too, at the present time there is a remnant chosen by grace. And if by grace, then it is no longer works; if it were (works),
grace would no longer be grace.
[As in Gal 5, Paul makes grace and works mutually exclusive, the one automatically excludes the other. . .for Jew and Gentile alike.
There is no mixture of the two in the gospel, and they should not be mixed in presenting the gospel, for that is to present a false gospel. Anathema!--Gal 1:7-9.]
What then? What Israel sought so earnestly (a right standing before God)
it did not obtain, but the elect did. The others were
hardened (because they pursued righteousness by works
instead of by grace
alone, through
faith, 9:30-32)), as it is written:
'God gave them a spirit of stupor, eyes so that they could
not see and ears so that they could
not hear,
to this very day.'
And David says: 'May their table become a snare and a trap, a stumbling block and a retribution for them. May their eyes be darkened so they cannot see,
and their backs bent forever (results of the divine
hardening from God, as punishment for rejecting right standing with God by grace
alone, through
faith).
But where is your support for saying that Paul 'insists on the replacement of the Jewish Covenant with Christianity'?
Ro 10:4 -- "Christ is the end of the law so that there may be righteousness (right standing with God) for everyone who believes."
And then there is the
NT letter to the Hebrews which in chps 7-9 clearly teaches the
setting aside of the Mosaic (Sinaitic) Covenant, the Levitical priesthood
and the cermonial laws, because the purpose for which they were given no longer exists. . .it has been fulfilled in Jesus Christ.

Jesus did urge a return to the Law and the Prophets
"The Law and the Prophets" means the whole NT, not just the Law. Jesus was referring to the whole OT's testimony to him, he was not referring to keeping the Law.
