FK, I don't know who your expert on Greek is, but he's just plain wrong about the appropriateness of translating "kecharitomene" as favored or kindness. That is not at all how the Greek Father's used or understood the word in this context and it was their language.
As for the rest of the comments, I'm rather impressed, at least to a point. Indeed Panagia, so far as Orthodoxy is concerned, was conceived with the exact same nature as all the rest of us and thus we reject the usual explanation of the Latin Church dogma of the Immaculate Conception. Every one of us has the same potential to have been "kecharitomene" as Panagia but no one save her, or so the Fathers teach, ever achieved that. It is for that reason that we can say that Christ was truly born of a human women, not some demi-goddess (which taken to its conclusion could create Christological problems) and that she is also the quintessential example for all humanity in her sinlessness, which she chose in distinction with our similar ability to choose holiness but instead we choose ourselves and our own pleasures and thus "miss the mark". She didn't, ever.
OK. I'm not really sure who he is either. He just seemed to talk in terms I have heard annalex use before. His name is Gary Zeolla and he apparently runs a website called "Darkness to Light". Oh well. :)
