It's literally one sentence. And it serves a couple of different purposes at the same time. I would call that efficient storytelling and gameplay.
It may be a single sentence, but the structure and content requires a fair amount of processing from the DM. Let's take a look:
"Drawing upon my previous life as an acolyte in service to the church on the Street of a Thousand Gods, I try to recall lore about the significance of this figure."
DM's Brain: "Drawing" -- what's he drawing, what's he drawing with? what's he drawing on?
DM's Brain: "upon my previous life as an acolyte" -- OK not drawing. What do I remember about the character's backstory? Was he an acolyte, and if he was, what is the relevance?
DM's Brain: "in service to the church on the Street of a Thousand Gods" -- Which church? Where was that again? This city? That city? What is the relevance?
DM's Brain: "I try to recall lore about the significance of this figure." -- finally an action! Why didn't he start with that! Oh, sure roll Religion check.
