Christ is the English representation of the Greek word Χριστός (Christos). The Christian religion takes its name from Christ, as a title given to Jesus of Nazareth, always capitalized as a singularly descriptive title meaning literally The Anointed One. In English translations of the New Testament, the Greek (Iēsous Christos), and related phrases, are almost invariably translated Jesus Christ or Christ Jesus, leading to the common, though inaccurate, perception that Christ was the last name of Jesus of Nazareth. The part of Christian theology focusing on the identity, life, teachings and works of Jesus, is known as Christology (see also Christian worldview).
The spelling Christ in English dates from the 17th century, when, in the spirit of the enlightenment, spellings of certain words were changed to fit their Greek or Latin origins.
