For your information, "Christ" comes from the Greek word "Christos," meaning annointed one. The meaning is not the same as Messiah from the Aramaic. The presence of the Greek language is important, because other words "Catholicos" (Universal) also have prominence in Christianity.
What happened was St. Paul began preaching the faith to the gentiles. Romans and Greeks, who were pagan and couldn't relate to the monotheistic God, could nonetheless relate to classical Greek philosophy. That is the reason why St. John's Gospel begins with "In the beginning there was the Word..." - it harkens back to the Greek logos, which we take to mean logic, but translates simply as "word."
It is the Greeco-Pagan innovations preached by Paul and authorized by Peter that form the beginnings of Christianity. That is to say, the faith became Westernized. The original believers called themselves the "People of God" (later adopted by English reformers until they adopted the derisive term of their Anglican detractors - "Puritans."). The first symbol of the People of God was the Icthus (that funny fish symbol which in very recent history has become popular in Evangelical circles, and has been parodied by evolutionists with their own version). Naturally, "Icthus" is Greek, and the phrase, "Jesus Christ, King and Savior" appeared for the first time. Eventually the term "Christ" was adopted and later on the Crucifix replaced the Icthus.
History lesson over - class dismissed.
