* εκλεκτός (eklektos): This is probably the closest and most common translation. It implies a deliberate and divine choice, often used in religious contexts. Think "elect" in English.
* επιλεγμένος (epilegmenos): This means "selected" or "chosen" and is a more general term, less implying divine intervention.
* αἱρετός (hairetós): This means "chosen" or "preferred," suggesting a choice based on merit or preference.
To choose the best word, you need to consider the *reason* for the choosing. Was it a divine selection? A human selection based on merit? Or simply a preferred option?
