Is it possible other denominations are right? Can we accept “also right?”

What if all that theology I learned is not what scripture was intending? Can scripture be right and my theology be wrong? How confident are you in your theology? Can you reconstruct it from scripture?

Question, largely for myself, does scripture reinforce my theology in multiple places, or do I have a few verses, out of context, that I rely on?

There seems to be an irony, and I’d love to be wrong here. Those who know the least scripture tend to be the most firm in their theology.

Is it possible, just maybe, that we have so many denominations not because some are right and some are wrong, but because people are so different and we need different communities, even in our belief systems?

Another thought. Maybe only a few denominations are extremely wrong and the rest of us are only a little wrong. Nobody is 100% right, right? Or, are we almost all mostly wrong, and that’s why we so need God’s grace?
