[chs68]

True, chi (X) is the first work of the Greek word for Christ or Messiah.

But "I" is, I think, the first Greek letter in Greek version of the name Jesus.

Somehow, I often get the feeling that those who refer to Christians as "Xians" derive some sort of satisfaction at using an "X" to describe Christ.

I confess that I could be quite wrong about that. But I do wonder why they never refer to us as "Iians". My own guess is that "I" somehow does not have the same effect as an "X".

Because we are not "Jesusians," we are "Christians." If you are going to use an initial, odds are it would be the "X" from the Greek for "Christ," rather than the "I" from the Greek for "Jesus."
