Matthew 16: 13-20
Peter correctly answers the question Jesus poses. Jesus says you are correct, but you did not know it yourself, “flesh and blood” did not revel it to you rather the Living God had, The Father. This is called the “Good Confession,” and it is essential. As Disciples of Christ, we say, “No Creed but Christ,” we say we have no creed. It is not that we reject creeds, but we reject creeds as a litmus test for fellowship. As it is stated in the first principle of the identity statement of the CC(DOC):
We confess that Jesus is the Christ, the Son of the Living God, and proclaim him Lord and Savior of the world, requiring nothing more - and nothing less - as a basis of our life together.
We start fellowship with a belief in Jesus the Christ, the Son of the Living God, we need nothing more or nothing less to bring us together as Church, which Jesus told Peter He would start with him, and this confession and handed him the keys.
Now Peter stated the correct answer, as Jesus made quite clear, the answer we depend on for our life together. Yet Peter did not understand his confession completely. First off a few verses later Matthew reports that Peter tries to rebuke Jesus’ passion prophesy, and Jesus said “get behind me Satan.” Peter claims he would follow Jesus and yet he denies Him three times. Peter was a first century Jewish man and thus his idea of the Messiah was influenced by that reality. The idea of the Messiah was to free the land from the Romans. They believed the Messiah would provide a victory, a military, and social victory for for the Jewish people. I find it quite evident that Peter must have had that hope with the sword on him, the sword he drew on the night of Jesus’ arrest, which Jesus rebukes and heals the victim. This is why Jesus said, “Shhhhhh!!!” about Him being the Messiah, Jesus realized that Peter did not get it, Peter had the correct revelation, but the true revelation would come through the flesh and blood on the cross and the resurrected man who told us “Peace.”
Peter had to be open to being wrong. Even after Jesus cooked him breakfast on the beach and asked him if he loved Him three times and told him to tend and feed His sheep, Peter still had to be open to being wrong. He believed the keys were about keeping people out, not to open the gates, as Peter was concerned about believers following the laws of the Torah, until God send him visions that made him realize:
Then Peter began to speak to them: ‘I truly understand that God shows no partiality, but in every nation anyone who fears him and does what is right is acceptable to him. You know the message he sent to the people of Israel, preaching peace by Jesus Christ—he is Lord of all. (Acts 10:34-36)
The key is that Peter was open to the joy of being wrong, a term I borrow from James Alison. This is not a joy of being lost or a joy of hurting others.
The best example of the joy of being wrong I can think of was a time I was driving the three hour commute from my seminary during my first year. I have many times I was wrong, but this one I believe can help you understand the joy of being wrong. See I told my friend I thought I was interested in a woman, but I was convinced that I should not pursue her. I was convinced she was not interested (later to learn she did not pick up on flirting well). I was convinced I was right. Half way home, I decided to ring her, I was open and hopeful. She answered, “who is this"?” but by the end of the conversation we had a date planned and rest is history, as we have been married for six years. That is the great joy of being wrong.
We do not expect young people who are just baptized to fully understand their good confession that Jesus is the Christ the Son of the Living God. We expect them to continue their education to continue to disciple. All of us need to be like Peter and be open to being wrong, even looking for the joy of being wrong. For Peter it started with the Good Confession and ended up opening the Kingdom of Heaven to everyone.
We simply need Christ, nothing more—nothing less, to begin our life together as Christians and we need to be open to learn and change what we think we know the Messiah is. We could be wrong and that can be full of Joy.
