First, as has been pointed out, but not very clearly, is the difference between Christ and Jesus. There are many who submit to the teachings of Jesus, but don't consider him "the Christ". Then there are many who believe that he is the Christ. And then there are many people who think that Christ is his last name.
Since the very basis of christianity is the belief that Jesus was the Christ, I'll assume that a true christian is one who follows the teachings of Jesus of Nazareth. However, the big problem with this is that not one record of his teachings that have not been interpreted by other men who had their own agenda actually exist. So that leaves no choice but to have the majority of christians to decide upon an individual or group who has the divine authority to cherry pick those surviving gospels to represent his teachings as best they can.
Now all we need are a group of christians that can agree on what Jesus said and how he said it and we'll be half way there.
