The Merriam Webster dictionary defines the word "holy" as exalted or worthy of complete devotion
as one perfect in goodness and righteousness. Divine. Devoted to the deity or the work of the deity.
Having a divine quality. Venerated as or as if sacred.
Since there is no such thing as a deity, what is really "holy"? The word can be used as an intensive such
as "holy terror "or as a mild oath such as" holy smoke "as Thomas Wolf famously demonstrated.
I can't think of anyone or anything "holy". Can you?
