Theists always ascribe perfection to their gods. If true, then the words used or inspired by their gods would be perfectly precise. In this case, god-inspired scriptures would be unambiguous in whichever language the god inspired them. Because there would then be only one meaning, there would be no room for interpretation, and thus there could be only one true religion based upon those scriptures.
This of course assumes that the god created or taught humans to know the perfectly precise meanings of the words. If not, the whole exercise of inspiring the scriptures would be irrelevant.
On the other hand, the god might have instead appreciated the beauty of ambiguity in language, and thus might have inspired the writing of scriptures that are perfectly ambiguous.
In this case, there would be no fixed meaning or interpretation, and basing a religion on the scriptures would be pointless.
Or are we to assume that the god’s perfection does not include the perfection of language? In this case, too, the scriptures would be an unsteady basis for a religion.
It is outrageous! If the scriptures are not perfectly clear, then a whole industry of interpreters could spring up, some of whom might be charlatans, or maniacs, or even simple money grubbers!
