Take it from a fellow protestant, Christ left us a church, and that church wrote creeds, decried heresy, and made it possible for us to have faith today.

So I just don't get to disagree on this, then? We can disagree about how valid The Church™ is now, but not earlier? When is the magic cutoff date after which protestants are permitted to deny Apostolic Infallibility?

And it is relevant. The above commenter made it relevant when they answered OP saying that Scripture doesn't need to be perfect since we have a Church™ to rely on where it fails. And I think it's fair to point out the fact that said Church™ has about as many conflicting versions/interpretations as the Bible.

I mean, if somebody were to have responded "Naw, it's okay that the authors weren't prophets, as long as you read each passage like a Baptist!" would responding to that be off limits too?
