Christos (Greek) Anointed; applied in the Greek Mysteries to a candidate who had passed the last degree and become a full initiate. Also the immanent individual god in a person, equivalent in some respects to Dionysos, Krishna, etc. The Hebrew word for anointed (mashiah) is generally written in English as Messiah. What we know as Christianity is a syncretism of borrowings from Neoplatonism, neo-Pythogoreanism, Greek Gnosticism, and Hebrew religion. Christos was commonly used in the Greek translation of the Bible as a title of the Jewish Kings, those who had been anointed for reigning -- a symbolic rite taken originally from the Mysteries. St. Paul's use of the word shows that he understood its true mystical meaning, but spoke with precaution in his public epistles or writings.
The first two letters of the Greek word, , superimposed in a monogram, were on the military standard of the later Christian emperors of Rome, probably dating from Constantine, and have a significance as geometrical symbols besides. See also
