Jesus has many titles and corresponding roles, most notably Christ. The English word, "christ", comes from the Greek word, "kristos", which has the same meaning as the Hebrew word, "messiah". A christ or messiah is literally an anointed person, or figuratively someone set apart with a special purpose. We use "christ" to describe Jesus, not because it's his last or family name, but because Christians recognize Jesus as having a special purpose. That special purpose is to help us overcome our ultimate enemies, death and hell. That special purpose is to be our savior.
