Entry for Jesus Christ from Amtract Dictionary
Personal Comment – The terminology is very specific. Jesus Christ is a person that exists forever because he is fully God, and he took on humanity to complete the salvation of man’s souls. Jesus comes from the OT Joshua, or Jehovah is salvation. Christ comes from the concept of Messiah or the anointed to do a very special task before God. In Jesus’ case, to execute salvation for God and mankind.
