As Jesus was speaking to His Jewish brethren, when he mentioned the Gentiles, He said,
As the Father knows Me, even so I know the Father; and I lay down My life for the sheep. And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd. John 10:15-17
The Bible categorizes humanity into two groups of folk: Jews and Gentiles. The definition a Gentile is anyone who is not of the ethnic Jewish heritage. When we understand these two categories, then we can have a better understanding of the two constituents of the Bride of Christ who have been justified by faith (Jews) and through faith (Gentiles).
Or is He the God of the Jews only? Is He not also the God of the Gentiles? Yes, of the Gentiles also, since there is one God who will justify the circumcised by faith and the uncircumcised through faith… Rom 3:29, 20
There is nothing as pristine as Scripture itself! The Apostle Paul tells us in Ephesians chapter two exactly how Jesus accomplished this.
And you He made alive, who were dead in trespasses and sins, in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the Heavenly places in Christ Jesus, that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus. For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
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.
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. And He came and preached peace to you who were afar off and to those who were near. For through Him we both have access by one Spirit to the Father.
Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God, having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, in whom the whole building, being fitted together, grows into a holy temple in the Lord, in whom you also are being built together for a dwelling place of God in the Spirit.
Is the Gentile or Christian Church separate from the Commonwealth of Israel? Did we replace Israel? Is that our understanding of what Jesus taught? Did Paul, the Apostle to the Gentiles teach, “Too bad for Israel, they missed the Messiah so their out and God decided on the Gentiles? We’ll see just what Paul thought about the matter in Romans 9, 10 and 11.
