Here's the definition from the English - Ancient Greek Dictionary. Christ = Xristos -
The greek letters would not translate in the HTML posting environment. However it is Chr - Ro - Sigma - Tau - Omega - Sigma to wit Kristos (with an X!)
That should be Chi-Rho-Iota-Sigma-Tau-Omicron-Sigma for Christos (accented on the final syllable in Greek, with both vowels short).
