Well, by nature, no human institution functions as gatekeeper between me and God, and Orthodoxy/Catholicism absolutely aims to do that. By study, you find out that the early Church debated quite a bit about topics such as which scriptures “counted,” and a lot of them were excluded or edited heavily in an effort to reconstruct them from bits and pieces of different manuscripts. By thought, certain ideas like the Trinity are nonsensical, and God wouldn’t expect us to forsake logos as an article of faith, that’s something a demon would come up with.

You have a strange fixation with the canon of Scripture. No one was even talking about the canon in the early Church.
It wasn’t an important issue, individual churches just used whatever Apostolic writings they had on hand, which we know from citations are mostly identical to what we have today. We went over this in another thread, and I even linked you to a collection of the Apostolic Fathers that proves it by noting all the citations.
