" Euthyphro offers as his first definition of piety what he is doing now, that is, prosecuting his father for manslaughter. Socrates rejects this because it is not a definition; it is only an  example or instance of piety. It does not provide the fundamental characteristic which makes pious things pious. "

That basically sums it up.
