Christ is the English term for the Greek word Χριστός (Christós), which literally means "The Anointed One." The Hebrew word for Christ is מָשִׁיחַ (Mašíaḥ, usually transliterated Messiah).
The word is often misunderstood to be the surname of Jesus due to the numerous mentions of Jesus Christ in the Christian Bible. Often used as a more formal-sounding synonym for Jesus, the word is in fact a title, hence its common reciprocal use Christ Jesus, meaning The Anointed One, Jesus. Followers of Jesus became known as Christians because they believed that Jesus was the Christ, or Messiah, prophesied about in the Tanakh (which Christians term the Old Testament). The majority of Jews reject this claim and are still waiting for the Messiah to come (see Jewish Messiah). Most Christians now wait for the Second Coming of Christ when they believe he will fulfill the rest of the Messianic prophecy.
