Is the Protestant Authority?

What are the essentials of protestantism? And it's not something that i've put enough thought into to like, asher come down defint answer. I think that the issue of the canon, inspiration and solo scriptura, i really do think those are to be protestant. So let's say rowser and white will really disagree about how to understand alleged genecide in the old testament and inerency, but they're gong to both agree the books describing them are in. That's what we have to wrestle with.
