I came across a quote on fb this morning:

The function of Theology? The recitation of the incomprehensible by the unspeakable to pick the pockets of the unthinking.~ Robert Anton Wilson

Not so sure I would use the ‘unspeakable’, I might prefer to put it this way:

The function of Theology? The recitation of the incomprehensible by those with dictionary diarrhoea to pick the pockets of the unthinking.

After all, if one was incapable of expressing in words, how could they recite the incomprehensible?
