Jesus is God's annointed one - King and Priest.
Thanks for your question.
Jesus is the Greek form of the Hebrew name Yahshua or Yeshua [English Joshua] and it literally means "Yah [God] is salvation". Christ, in Greek, is Kristou or Khristos and it is the Greek translation of the Hebrew word Messiah. So, to say Jesus Christ in English is the same as saying Jesou Cristou in Greek or Yeshua ha'Mashiach in Hebrew.
Both Christ and Messiah mean "annointed" in Greek and Hebrew respectively. So, when we say "Jesus Christ" we are saying "Jesus, the annointed one." The two names together mean something like "God saves through His annointed one."
I hope you have found this helpful.
