I wasn't going to be part of the "is it real/is is myth" question. So there isn't anything productive in me entering the "personal/communal" question, either.

Except to say this: I, personally, usually address my God as "Lord God" or "Father God", both of them titles. I cannot speak about US Christians, but all of the AU Christians I know would use the same or similar titles. And probably not be bothered about whether it's a title or a name for God. :-) And lastly, while we do regard our relationship as personal, we also believe that it is the same God we all have a personal relationship with.
