Armenian Greetings

Each language has its own form of greeting. English is fairly informal, and the greeting has no particular meaning ("Hello"). On the other hand, Hebrew and Arabic both use "Peace" as a greeting. However a friend of mine pointed out today that the standard greeting in the Armenian language is "He is risen." to which the other person replies "He is risen indeed." Considering Armenia was the first country to nationally adopt Christianity, this is particularly interesting. However, most Armenians today would not realize the significance of their greeting.
