A transcript of the text, which comes from Dot, Dot, Dot: Infinity Plus God Equals Folly:
For some centuries now, theologians have implied that infinity is intrinsic to God, and we should wonder why. The answer isn't so hard: because it has to be. When "God" was conceived, at least in the Abrahamic traditions, he lived on a mountaintop. When people climbed the mountain, God wasn't there to be met, and when they descended the other side to meet new people, they were forced to place God in the sky and make God big enough for both peoples. We've been to the sky; in fact we've been above it. God isn't there either. He did not meet us in low earth orbit; he did not meet us when we walked upon the moon; and our robots have not found him on any planet in our solar system or, now, just outside it. Our telescopes cannot see him, even as they peer out into the apparently edgeless universe, and so people have moved God beyond the universe to an imaginary realm, and as God went, they've had to make him big enough to account for it all.
Within that "all" is not only every conception of God that humans have entertained and worshiped, but also every potential notion of God that is conceivable. Monotheism demands it, in lieu of an actual physical God of this world. The potential conceptions of God are infinite, and so God too must be infinite to usurp them all. But as we've seen, God cannot be infinite, unless believers would accept he must also be abstract--that is, mental stuff. Though apologists may defend this idea of God, a majority of believers do not accept an unreal philosophical deity of this kind. Theirs is a living, breathing, acting agent who will one day judge the living and the dead, and this is a fact too easy to lose sight of when talking with apologists.
