What is a Christian?

The only answer that can be provided is that a Christian is someone who believes in, and follows, the teachings of Jesus-Christ. However, having said that it must be stated that such belief and what follows as a consequence, are subject to many interpretations. There are many religions and sects claiming to be based on the teachings of Christ, but this very multiplicity shows that there is no common accord, and disagreement and schism are the rule. There is no means of establishing which of the many is the closest to the original teachings.
