Sulla, it is interesting that you mention written tales of dieties of other cultures having interacted with humans in the same paragraph as your citing the written tale of your deity having interacted with humans but apparently don't equate them.
Not sure what you mean. I think that the old gods really did exist: Zeus really was some amazing guy (or set of guys) who was viewed as a god after his death. Gilgamesh (or his composite) really existed and he had a mother who was considered to be extra special in some way. I'm partial to Girard's approach to violence, sacrifice, and religion. In this view, the main problem to be solved for men is how to live together without society devolving into some sort of Hobbesian nightmare. Communal violence is the answer. Of course, it is also the problem. But that's another discussion, I guess.
But your point is again intriguing, how ancient is the idea of a deity that is remote, distant and only accessible unidirectionally through prayer? Has any cult actually attempted worship of a deity without some form of occassional claim of active presence?
I don't know: Plato, maybe? Pythagoreans? Not too many, I don't think. That's one reason I think Girard is on to something.
I'd hazard to guess a psychological necessity behind doctrines like the presence through the eucharist, or Dionysus proving his presence through annually changing water to wine. The perrenial absence of the deities is perhaps just too much to swallow without some form of reassurance of invisible prescence through rite and miracle.
Well, yeah. Unless you are some freaky Gnostic or Platonist or something. That's one reason sacrifice has been the way in which people worship throughout 99.999% of human existence. A corpse is real.
I really know of no practising Christian who doesn't believe that Jesus (or angel) isn't at least once in a while bodily nearby.
Heh. You should hang out with more Protestants, they don't do the Real Presence so much. Hell, most Christians don't really think Jesus even has a body now! True story: My old parish had a poster they put up during stewardship month (when you sign up for various activities for the year: teaching Sunday school, food drive, whatever). It said, "He has no hands but yours." The point being that Jesus, being a spirit, cant go around lifting canned peas to stock the food bank. After a week or two, they changed it out to a slightly different slogan: somebody had pointed out that the first poster was actually heretical in that it denied the Resurrection. The central claim of the Christian faith being that Jesus most emphatically does have hands now.
