I don’t fully comprehend your emphasis on doctrine. Jesus never placed doctrine at the center of his good news. If anything he marginalized notions of doctrine (e.g., the sabbath is made for man). Thus, IMHO, I think any talk about doctrine (as typically conceived in our fellowship) as a central concern is a grave error. Wrong right out of the gate. If Jesus is our hermeneutic then doctrinal conversation should always be a marginal conversation. The early church was called The Way. Not a way of believing but a way of living. To miss that point is to, well, miss the entire thrust of Jesus’s life. Again, in my opinion.
This is such a good example of postmodern thinking. It makes Jesus into our own image rather than listening to what Jesus said. Consider how important Jesus considered his sayings, teachings, or doctrine:
Matthew 7:21-23 Hearing but not doing my words is like building on sand. The one who enters the kingdom of heaven is the one who does the will of God.
Matthew 10:14 “Whoever does not receive you, nor heed your words, as you go out of that house or that city, shake the dust off your feet."
Matthew 15:1-14 The teachings of men render worship vain. Every plant (human tradition) not planted by my Father will be rooted up.
Mark 8:36-38 “For what does it profit a man to gain the whole world, and forfeit his soul? 37“For what will a man give in exchange for his soul? 38“For whoever is ashamed of Me and My words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when He comes in the glory of His Father with the holy angels.”
Mark 13:31 “Heaven and earth will pass away, but My words will not pass away."
John 8:31-32 “If you continue in My word, then you are truly disciples of Mine; 32and you will know the truth, and the truth will make you free.”
John 12:48-50 “He who rejects Me and does not receive My sayings, has one who judges him; the word I spoke is what will judge him at the last day. 49“For I did not speak on My own initiative, but the Father Himself who sent Me has given Me a commandment as to what to say and what to speak. 50“I know that His commandment is eternal life; therefore the things I speak, I speak just as the Father has told Me.”
“Sanctify them in the truth; Your word is truth. 18“As You sent Me into the world, I also have sent them into the world. 19“For their sakes I sanctify Myself, that they themselves also may be sanctified in truth.
20“I do not ask on behalf of these alone, but for those also who believe in Me through their word; 21that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me.
John 18:37 Therefore Pilate said to Him, “So You are a king?” Jesus answered, “You say correctly that I am a king. For this I have been born, and for this I have come into the world, to testify to the truth. Everyone who is of the truth hears My voice.”
This is a simple and hardly exhaustive sample of the high place Jesus placed upon his words or his teaching. Jesus placed His words in a critical role. We are commissioned to preach and teach the gospel (a message). Whether people believe that message will determine their relationship with the Lord and affect their eternity.
It is "sand theology" to treat the teaching of the Lord as if it doesn't matter.
