You accept no authority? You think the church was a Christ-founded, Apostle-structured community until the death of the first-generation successors of the Apostles, and then became a "community" of atomized individuals? Each one of whom was equally well-equipped to determine doctrine, even if they disagreed with thousands of other equally-well-equipped individuals?
That's not how it actually happened, historically. If I believed that way, I'd call it "Missusdonnoism." And I'll admit, it has its advantages. You never need to accept any truths bigger than your own hat-size.
I accept the authority of God and HIs Son Christ Jesus. I follow His law and His teaching. That is sufficient.
What is all this about "doctrine"? The way to live is well documented in the Bible we have. The Urim and Thummim are alive and well in each heart.
I accept the truths that are made known to me so long as they square with the foundational principles in the Bible, and the teaching of Jesus found therein. What else do I need?
