I believe in an Ultimate, but I refuse to define it, characterize it, or refer to it as "God". My early upbringing saddled the word "God" with so much negative baggage that it's only useful as an expletive.

It's a bit analogous to the artist's idea that one can't draw an accurate depiction of a tree if one thinks "tree". Just thinking the word automatically brings to mind a stereotypical "tree" that interferes with one's ability to truly see the tree one is attempting to draw. But if one draws the shape of the negative space where the background meets the tree, there's no preconceived notion of what it is, no name for it and, thusly, a better chance that the resulting "tree" will look more like a real tree and less like a stick with a ball on top.
