the argument you are presenting is a red herring.
Paul had Timothy circumcised not because Timonthy needed to be circumcised because of his Jewish blood, but so he would not cause a scandel if he entered the temple and the Jews saw he wasn't circumcised.
Paul saw that being circumcised was no longer an issue for anyone.
If one wants to be circumcised, there is no law against it.
There is also now no longer any law requiring it for anyone. . . . . .
It is MAN who requires it now . . .. not God.
And the whole argument against "replacement" theology is a bogus issue. There is false "replacement" theology, such as "British Israel" where a nation replaces Israel.
No nation replaces Israel.
The CHURCH was the next step in God's redemptive plan, what the Jews were supposed to advance into. But because they rejected their Messiah, the good news went to the Gentiles without them (generally speaking). The Church is the FULFILLMENT of what the nation of Israel was only a shadow of.
When Jews turn to Christ, they become Christians. They no longer are Jews practicing Judaism which was a mere shadow of Christianity, which was the reality to come, what the shadow pointed to.
Types and shadows. . . . . types and shsadows end when what they were pointing to, their fulfillment, comes.
If you want to talk about replacement theology, then you have a problem, for Christ Himself "replaced" all that foreshadowed Him . . the passover lamb for instance.
There is legitimate "replacement", and to balk against that is a grave error.
