Thanks for this and for all your thoughtful posts.
I don't believe in a messiah. I am a follower of Jesus. Many of the early Christians were also followers of Jesus, who focused on his teachings and his example, not on his death or his purported resurrection.
People can and do argue over what makes someone a Christian. I don't regard those arguments as bad, except when people seek to exclude from the dialogue those with different beliefs.
About 10 years ago, I shared my beliefs with our college chaplain, who is a Christian minister, and I asked him whether in his view I can legitimately call myself a Christian given the fact that my beliefs do not match those of many churches. He answered that yes, I can, and my beliefs are very similar to his. He said that there are many Christians who believe as I do. They are a minority of Christians, but they exist.
Most Unitarian Universalist Christians seem to hold beliefs similar to mine, from what I can gather from surveys of people in our faith. Two summers ago, at church camp, I participated in a workshop on the New Testament led by a UU minister. There were about 40 people taking this workshop, and most regarded themselves as UU Christians. The minister at one point during the workshop decided to poll the participants about our beliefs. He asked how many of us believe in a literal resurrection of Jesus. No one said yes. He asked how many of us believe in a virgin birth. No one said yes. He asked how many of us believe that salvation comes only through faith in Jesus Christ. No one said yes. He asked how many of us believe that the Bible is the word of God. 1 person said yes. He asked us how many of us believe in following the teachings of Jesus. Nearly everyone said yes.
Those of us who reject what is commonly considered Christian orthodoxy are a minority among Christians, but we exist. I am not the only Christian who believes in Jesus as a great teacher and not as the messiah. Our college chaplain and the associate chaplain both believe that also, and they are ordained Christian ministers.
