Why don’t we need circumcision anymore, what changed?
What was it in the Old Testament that separated the children of Israel from the rest of the nations (that words “nations” refers to Gentiles).
What separated the children of Israel from the nations was the law of Moses, which included circumcision.
In order to bring about “one new man” from the two, the thing that divided Jew from the Gentile, the circumcised from the uncircumcised had to be removed.
The New Testament calls this thing that divided the Jew from the Gentile, the middle wall of separation.
Paul says it this way to the Ephesians - Ephesians 2:11-16
Therefore remember that you,
once Gentiles in the flesh—who are called Uncircumcision by what is called the Circumcision made in the flesh by hands— that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
- being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God
For He Himself is our peace, who has made both one, and has broken down the middle wall of separation, having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace, and that He might reconcile them both to God in one body through the cross, thereby putting to death the enmity.

The thing that divided Jew from Gentile was the law of Moses, with its ordinances that included circumcision, as well as Sabbath laws, and the death penalty for so much as picking up sticks to kindle a fire on the Sabbath.
The law of Moses was always temporary, as it was added until the Seed should, the Messiah.
What purpose then does the law serve? It was added because of transgressions, till the Seed should come to whom the promise was made; and it was appointed through angels by the hand of a mediator.
Galatians 3:19
It was added because of transgressions, till the Seed should come
The Point to everything mentioned here is to say, it’s pointless for you to try and quote scriptures from the law of Moses, and apply Sabbath requirements from the law, and not also apply everything else the law Moses commanded, which includes physical circumcision.
If you want to teach God’s people that the Church is observe the Sabbath, then you must show us from the New Testament, the instructions from Jesus and His Apostles how the Church is required to observe the Sabbath under the New Covenant.
