Theologians and preachers suffer many of the normal human weaknesses, finding what we want to see is a common example. When as a standard preacherly déformation professionnelle one adds a touching faith in the Humpty Dumpty school of linguistics.

There's glory for you!'

`I don't know what you mean by "glory,"' Alice said.

Humpty Dumpty smiled contemptuously. `Of course you don't -- till I tell you. I meant "there's a nice knock-down argument for you!"'

`But "glory" doesn't mean "a nice knock-down argument,"' Alice objected.

`When I use a word,' Humpty Dumpty said in rather a scornful tone, `it means just what I choose it to mean -- neither more nor less.'

`The question is,' said Alice, `whether you can make words mean so many different things.'

`The question is,' said Humpty Dumpty, `which is to be master - - that's all.'

Alice was too much puzzled to say anything, so after a minute Humpty Dumpty began again. `They've a temper, some of them -- particularly verbs, they're the proudest -- adjectives you can do anything with, but not verbs -- however, I can manage the whole of them! Impenetrability! That's what I say!'

There's what I think is a fine example of Humpty Dumpty theology quoted on Mary's blog - I can't comment there as to stop the dreaded spammers she has comments set so that only people with a login to her blog can comment :(

It comes from a wonderful small book called The Practice of Communicative Theology, by Matthias Scharer and Bernd Jochen Hilberath. On page 38 of that book they write:

The word “aggression,” from the Latin ad gradere
(”moving toward”) has a positive as well as a negative meaning. It includes no only the life-destroying forces of exclusion but also that force which can find expression in a living, loving relationship. All-encompassing peace and harmony among all creatures without doing away with their differences are ideals corresponding to the transformation of life that God promises for God’s future…

Whatever the Latin ad gradere meant - and although no Latin scholar I suspect that (or perhaps even more relevant what the range of meaning of agressus was the English "aggression" simply does not mean what these authors want to make it mean - no dictionary I have consulted permits it, and even the recent usage in phrases like "an aggressive advertising campaign" permit it either. Aggression means attack, whatever the Humpty Dumpty theologians wish. The etymological fallacy is still a fallacy, even as we near the half-centenary beyond the publication of Barr, James. The Semantics of Biblical Language. London: OUP, 1961.
