"Christ" was NEVER a "name" as such in Christianity, as you have been told by now dozens of times. It was merely USED LIKE a name, just as you say "the Queen" or "the President". And you cannot have a name with a definite article, that really should be obvious to anyone. And the second name "Christ" is a GERMAN second name. "Christ" in German means "Christian". "Christ"(the English word) is "Christus" in German.

I am getting bored with this, as you STILL have not told us why on earth Mohammed is the paraclete/holy spirit....
