Branch theory of Christianity and Islam deals with major confessional splits, referred to as schisms or churches, etc in and of themselves. The nature of disunity involved has much to do with a political and regional infrastructure basis upon which Jew and Arab cultures were grafted, such as the Illyrian, Italian, Gallic and Oriental tetrarchs of Rome. Indogermanic religion is much the same, so it's not a case of different religions any more than Orthodoxy, Catholicism, Protestantism and Islam are ultimately different religions.

Having autonomous traditions don't take away from common origins, so there's as much similarity in Hinduism, Olympianism and Heathenry. None of us can hide behind faith expressions as substitutes for genetics and somehow have solid ground to work with for adjudicating physically manifested boundaries. Confessionalism asserts community acculturation to a prescribed set of theologies and rituals, which may or may not be a variation on a theme with the next society over. Is there a genetic basis for convictions demarcating populations, or not? We are advised not to be bigoted schismatics where Christianity and Islam are concerned, whilst others are drivers of schism by professing to own beliefs as if they can be intellectual property on the soul.

The truth is, it's palpable how networked Indogermanic cultures are in religiosity and linguistics, with DNA backing it up also, but are there Christian or Muslim languages, genotypes and phenotypes? Who speaks of the Christian race, or Christian nationalities? Race and nationality are fundamental to our very being and Christianity is optional veneer, that cannot be sourced to Indogermanics, any more than soy or guacamole are sourced to Indogernanics despite our use of them.

Sure, Romans could adopt Judaism and pass it off as Christianity, just as Persians could adopt Sunni and pass it off as Shi'a, but it doesn't happen naturally. Indogermanic confessionalism arises from metaethnic evolution into distinct forms due to geographical separation and bottlenecking experiences. How much of Christianity can reflect Indogermanic society, when it's but a Greek, Latin, Germanic or Persian translation of Hebrew, Aramaic and Arabic, before it can even be thought of?

What then animates Christianity and Islam, but a commitment to disavowal of inherent Indogermanic culture, against natural order? The attempt toward monolithic Jew globalism in Abrahamic religions hasn't kept Christianity or Islam according to unity of purpose when each was in the original Aramaic or Arabic, so what's the point of insisting on playing junior partners as Indogermanics, when those are still Semitic, even if not strictly identical to Judaism? How could synthetic confessionalism be Indogermanic and how can any deny organic confessionalism?
