I found the question I remembered, and for all I know you are the one who asked it.

Unfortunately, I couldn't find anything that time either, because its not actually in the rules.
I didn't read Church of Sigmar carefully enough the first time. It doesn't target a card in your discard, its an effect that modifies your opponent. However, by this logic it also affects a unit that is in your hand, or a unit "just played" and still on the stack. This is not how its supposed to work.
I talked about this card with Lukas at FFG, and he said "Church of Sigmar should only affect units you control that are in play." and "Unless otherwise stated, constant effects only apply to cards in play."
That's the most official answer that is possible until an updated FAQ is released.
Edit: Update - the Church modifies the opponent rather than your cards, so if it is a "target" effect on a card in an out of play zone, then the Church still works.
