The journal says to go to the church, but there's no options to pick from to initiate anything beyond the usual. I've already passed a couple of  weeks in-game thinking maybe there'd be a scene or something that'd pop up to initiate the quest proper or change something at the church, but nothing's happened. Did I miss something?

Do you use any mods? It should work from town screen

Yeah, that was it. Deactivated some of the mods and that fixed it.
