Christ is a metaphysical title. If you say you believe in christ then you say you believe what this title stands for.
If you say that you follow jesus you doesnt necessarily have to buy into the christ stuff.
I mean what if I argue that Jesus as a person never actually existed but the idea of jesus as the ideal man serves as a guide and example for how people should live their lives? OR if I believe that jesus was not of a divine nature but was instead a moral teacher who's teachings should serve as a similar guide?
If not a christian (in terms of common parlance) what do either of those make you then?
