I personally am of the opinion that the J/C prayer "paradigm" is a misconception of the Jain/Persian/Hindu notion. The idea of speaking, using your voice, is something in the Eastern religious dogma that is to do with chanting, i.e. meditation; however yogis eschew all physical action and try to commune directly with "God", or the Supreme, the Whatsit, the Unknowable.
These Eastern religious ideas are where much of the Judaeo-Christian theology came from, but they've "evolved" into concepts of "worship" -by talking directly, or chanting a prayer.
The notion of some ultimate Truth, or an Unknowable, refers to the non-conceivability (by an intellect), of it. It can be experienced, but not rationalised or described in words, as such.
I think of it the way music isn't anything until an instrument plays it, if you see what I mean. You can write down some symbols, that "represent" the tune, but this representation is a product of a mind, wanting explanation. In that sense, you could say sheet music is a way to explain music, like a scripture (say the Mahabharata), is the same kind of thing (a representation, or rationalisation), but it's never the thing itself.
(this should get someone going...)
