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?
