Let me see if I got this straight. Though "all Scripture is God-breathed" (2 Timothy 3:16a) there are only a few who can discern it's meaning without infallibility ...
So our Divine Savior also has established His Supreme Court --- His Supreme Judge --- to give us the true meaning of the Scriptures, and to give us the true revelation and doctrines of the Word of Jesus.
... and only these few can tell us what it truly means even though it may contradict what we read of God's word with our own eyes least we fall into heresy.
Jesus, though he was not a member of the clergy, read and studied God's word for Himself. And He discerned for Himself what it meant. He was often in direct conflict in His understanding with the established clergy which claimed for themselves the God given right as the only ones who could discern God's word without err.
It would appear that this lesson from Jesus is in direct conflict with the sermon in this article. It shows that religious bodies can be as fallible as men. This sermon asks that I follow the word of only the clergy. But I have to ask in return "what did Jesus do?"
Well, Jesus is God so His ability is somewhat superior to yours. No offense
