Julia,
I had another thought: I was an elder in the US for over 20 years and I never once heard another elder refer to anything as "the ‘apostasy’ question."
I heard it asked (and may have even asked it of other), but no one here ever used that term.
Unless it's different where you are (New Zealand? Australia?), you may just want to have the antagonist, Brother Wanis, ask the question and then have Alfred respond indignantly, "How dare you question my loyalty after all my years of faithful service to Jehovah ..... "
Oubliette
