are there any or has there ever been any sects/denominations of christianity that were skeptical of or opposed to pauline christianity?

just the more i read about it the more hilarious/insane it is.

like...you have jesus. and you have his followers. then jesus dies. and his followers are left to preach his word and whatnot. then after years and years of doing all this work and building this jewish christian community.

then comes this dude named paul. not just any dude. but a pharisee who openly admits to having zealously and violently persecuted christians. and he's like "hey we should preach to the gentiles."

and you and all your bros (who literally knew jesus personally in the flesh and travelled with him and stuff) are like "no you have to be a jew to be a christian, sorry."

and then paul is like "actually no. i saw jesus in a vision. i think i know better. we're going to preach to the gentiles." and then he goes off and just starts sharing your little cult with all of these foreigners but a really strange version whose theology is quite different from what you understood and he writes these letters where he just says shit and people treat those letters literally like the word of god.

it just blows my mind. how did/do people buy that? he's just some nobody and all of his authority rests on his "i had a vision". and people ate that shit up. lmao.
