In Christianity, Christ (Greek Χριστός, Christós, meaning "the anointed one") is a title for the saviour and redeemer who would bring salvation to the Jewish people and mankind. Christians believe Jesus is the Jewish messiah prophecized in both the Hebrew Bible and the Christian Old Testament. Christ, used by Christians as both a name and a title, is synonymous with Jesus. The role of the Christ in Christianity originated from the concept of the messiah in Judaism. Though the conceptions of the messiah in each religion are similar, for the most part they are distinct from one another due to the split of early Christianity and Judaism in the 1st century. Though the original followers of Jesus believed Jesus to be the Jewish messiah, e.g. in the Confession of Peter, before the crucifixion and resurrection, Jesus was usually referred to as "Jesus of Nazareth" or "Jesus, son of Joseph". Jesus came to be called "Jesus Christ" (meaning "Jesus the Khristós", i.e. "Jesus the Messiah" or "Jesus the Anointed") by his followers after his crucifixion and resurrection. Christians believe that the messianic prophecies were fulfilled in his mission, death, and resurrection. The Pauline epistles, the earliest texts of the New Testament, often refer to Jesus as "Christ Jesus" or "Christ". The word Christ was originally a title, but later became part of the name "Jesus Christ". It is also used as a title, in the reciprocal use "Christ Jesus", meaning "the Messiah Jesus", and independently as "the Christ". The followers of Jesus became known as Christians (as in Acts ) because they believed Jesus to be the Khristós or Mashiach prophesied in the Hebrew Bible. Jesus was not, and is not, accepted in Judaism as a Jewish messiah, and the concept of a divine messiah was always rejected by Judaism as idolatry. Religious Jews still await their messiah's first coming and the Messianic prophecies of Jewish tradition to be accomplished. Religious Christians believe in the Second Coming of Christ, and they await the rest of Christian messianic prophecies to be fulfilled. One of those prophecies, distinctive in both the Jewish and Christian concept of the messiah, is that a Jewish king from the Davidic line, who will be "anointed" with holy anointing oil, will be king of God's kingdom on earth, and rule the Jewish people and mankind during the Messianic Age and World to come. Muslims accept Jesus () as al-Masih, the messiah in Islam, and believe he will come again, but don't believe that the messiah is divine or the Son of God. The area of Christian theology called Christology is primarily concerned with the nature and person of Jesus Christ as recorded in the canonical gospels and the letters of the New Testament.
