On the contrary in Greece the name Christ is prevalent, not only in literature, but also in every day use. When we say Christ, we don’t feel the distance of a God, but also His humanity. In your country, when you say Jesus most probably you don’t feel only the presence of a man, but also His godly nature. On the contrary, when I read texts that use mainly the word Jesus I feel some alienation, as if the author somehow diminishes His person.
The angel announced the name “Emmanuel” (which means, “God is with us”), a name that at least in Greece became actually a common name, almost without any reference to our Lord. “Jesus Christ”, the complete form of His name, is used also very frequently (just remember, for example, the so called “Jesus Prayer”).
