Rev. 2:9

9 I know your afflictions and your poverty—yet you are rich! I know about the slander of those who say they are Jews and are not, but are a synagogue of Satan. 

Rev. 3:9

 9 I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars—I will make them come and fall down at your feet and acknowledge that I have loved you.

1 John 2:22

22 Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son. 

Romans 2:28

28 A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. 29 No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.

This is not Replacement Theology. It is about the Truth.

Only a Natural Jew who believes that Jesus Christ is the Son of God is the Real Jew.

Genuine Christian is a Spiritual Jew.
