When a person refers the christian object of devotion, the centre of their belief system, as “Jesus Christ”, they are not just calling a name. The phrase, “Jesus Christ”, is a claim.
Although the word “Jesus” is a bastardization of whatever Hebrew or Aramaic name the guy originally had – it is a proper name – the word “Christ” is a title, not a name. It is a title that assumes that the person connected to it is the anointed one, the promised descendant of King David, set to rule Israel and live in a time of a better world. Without going into the doctrinal baggage that has been loaded on the word, the fact is that this word “Christ” makes a huge claim about the one it is attached to.
When a person who knows to use his words with purpose and understanding sees that a person doesn’t fulfil a certain role, then he knows to avoid associating that role with someone incapable of fulfilling it (unless when joking around or using it insultingly and ironically). If a madman or commoner claims to be royalty, then the wise person doesn’t call such a person, e.g. King John, or John the King. You don’t call a unqualified person e.g. Doctor John or John the Surgeon. The title doesn’t fit the person.
Jesus failed to fulfil all the explicit requirements set out in the Jewish Bible. The clearest statements in the Jewish Bible about the future king contradict the life and times of Jesus to the point where the new testament’s depiction of his birth destroys any claim that he is an adequate descendant of King David, to the point where christians spiritualize and allegorize the Jewish Bible’s criteria, or claim a second coming (a tacit admission of the failure to fulfil criteria in his “first” coming). Jesus failed.
So to the conscientious objector of christians’ messiah claims for their chosen figure, be careful with your words. If you don’t accept their claims and the claims of the new testament, then there is no “Jesus Christ”! There may be a Jesus, a Yeshua, a Yeshu, a Nazarene, a person known as “that man”, a fool and a failure, or a man who was mistaken for something he wasn’t. But there is no Jesus who was “the Christ”. If the name makes a claim and you know the claim is unfulfilled, then don’t let your words agree with the claim or the assumption.
“Jesus Christ” is a claim. With that claim being unfounded, then to state it is a lie.
Or a joke.
