@Sui >Cultures change yeah, but if being born a jew is all it takes for an instant dismissal of everything then it still applies.

I think you're missing the magnitude of Christ's birth, death, and resurrection as it pertains to old testament religion beliefs. The decision to reject Him is such a big deal when they were waiting for the Messiah for centuries. To use a metaphor, if (actual, provable) Adolf Hitler suddenly appeared today, and some group of wignat podcasters called him cringe and murdered him, would you call them Nazis or would you think them something else? There comes a point where action defines who you are, regardless of what you LARP or the aesthetics you adopt. The "Jews" of today are not the same as the ones who faithfully practiced and awaites the coming Messiah when Jesus was born.

>Christianity significantly altered at multiple points...100s of sects.
There are specific significant points in Christian history where things were decided at councils. We have old writings and things like The Didache which line up pretty dang close to practices 1900+ years later. Heterodoxy doesn't matter to me; core tenants of the faith were hammered out in discussions at councils. The Christian whose church is in a run down stripmall is still a Christian, as is the one in a grand cathedral.

>But judaism is a more direct adaptation of jewish mythology.
These types of statements are illogical, and I've already pointed out that they cannot practice their religion as written. They have no temple to sacrifice, they have no class of priests to perform them, and they have invented rules turning their beliefs into a game. "Lol I'm not traveling or there's a big wire up there that I claim is part of my house". If that's always been a part of their religion, then it's no wonder Christ called them out.

>General blasphemous statements
Jesus Christ was born of a virgin. The people who try to make explicit claims otherwise tend to get their information from The Talmud. And to once again repeat my point: the "jews" as they exist today are a religion of larpers who rejected Christ and had to make up a new version of rules for their beliefs to try to jew God into accepting their legalism.
