The name "Jesus" is derived from an Aramaic (ancient Hebrew) word, Yeshua, which means "savior." Thus, the original use of this term is as an honorific title, such as "rabbi." The central personage of Christianity is called Jesus Christ, but this is not his birth name, it is an acquired title. Very little is known amongst the masses of the true details of his life, save that he appeared on Earth some two thousand years ago and ignited a flame that few comprehend or embody. His teachings are most known in the Gospels of the New Testament Bible, but are also present in The Pistis Sophia and a variety of other texts.
