Star Trek and Q

I have just come across an interesting passage about the relationship between the character Q in Star Trek: The Next Generation and the postulate Q in the Synoptic Problem in a book by Michael Barrett and Duncan Barrett called Star Trek: The Human Frontier (London and New York: Routledge, 2000):

The name may have various sources; an obvious one is 'question' or 'query'. Another possibility is the gadget expert in James Bond films. It has one relevant history in Christian theology, where the so-called 'synoptic problem' of the authorship of the gospels is held by some to involve a 'hypothetical entity' responsible for the creation of parts of these texts not otherwise explicable. 'To postulate Q is to postulate the unevidenced and the unique.' Q is here a sort of residual category, invoked when need arose and now, it seems, the subject of much controversy. (82-83)

It's particularly gratifying to me to see Austin Farrer's "On Dispensing With Q" getting quoted in this context, and to see Q described as "the subject of much controversy"!
