What is the origin of the original Christian church?

Christianity and Islam are Spiritual Pogroms of the Jews.
Judaism was founded by Jews, for Jews.
Christianity and Islam was founded by Jews, for Gentiles (non-Jews).
A Gentile can be a Christian or Muslim, but they cannot be a Judaist.
Only Jews are allowed to practive Judaism.

And Rabbi Yoḥanan says: A gentile who engages in Torah study is liable to receive the death penalty; as it is stated: “Moses commanded us a law [torah], an inheritance of the congregation of Jacob” (Deuteronomy 33:4), indicating that it is an inheritance for us, and not for them. - Sanhedrin 59a:2

Thus, Jews are born into Judaism.
Being "Jewish" is a Race, not a Religion.
Judaism is a protective mechanism of the Jews.
Jews warn other Jews against falling for their own bullshit, Christianity and Islam.

For a Gentile to practice Christianity and Islam, means to curse oneself.
But to engage directly into Talmudic practices, one is asking for death.
Either way, all Jewish practices lead to Soul Death. Known also as "Second Death".

While we're on-topic, Buddhism also preaches the "Second Death" as "Enlightenment".
Buddhism is Jewish, and meant only for Gentiles.
Altogether: Judaism, Christianity and Islam form Abrahamism.
"Abraham" is a Jewish myth of the "first Jew" that never existed in the first place.
They have made up their own "history" and "faith". Their own "mythos".
