People who take the Third Commandment seriously sometimes get upset when others do things like say "Jesus Christ" when angry or surprised, but they might be shocked to learn that the name "Jesus Christ" is an amazing mangling of His actual name. Let me break it down for you.
Jesus- from Spanish Jesus (hey-soos)
Jesus- from the Latin Jesu (yay-zoo) or Iesu (ee-eh-su), as in "Jesu, Joy of Man's Desiring"
Jesu- from the Greek Yeshu or Ieshu, because Latin has no "sh" sound.
Ieshu from the Hebrew Yeshua or Yehoshua, meaning "God is Salvation", which makes perfect sense when you look at Matthew 1:21 "And she shall bring forth a son, and thou shalt call his name JESUS (Yehoshua): for he shall save his people from their sins."
Yehoshua is the root of our name Joshua.
As for "Christ", it comes from the Greek
krystos and has the same meaning (it was the word Paul himself used) as the Hebrew word
messhiah, literally "the anointed one". Obviously, that's where we get the word Messiah., and this is also why Paul calls Him "the Christ" so often in the Epistles.
So it is actually more accurate to call Him "Josh, the Anointed One" than it is to call Him "Jesus Christ". Of course, I'd feel a little goofy yelling out "oh Josh" the next time I smash my thumb with a hammer.
