Read the church building as an ordered path through worship. This page starts with that question because it is the most useful way into the subject. It names the visible structure, keeps the vocabulary plain and points to the source trail instead of asking the reader to accept an unexplained conclusion.
The useful distinction here is between what a visitor can see and the interpretation attached to it. A threshold, screen, candle or garment is first described as an object, then connected to the wider vocabulary of worship. The Feast & Form Index gives this explanation a place among related records: feast, season, office, object or visual cue. That arrangement lets a reader arrive through ordinary language and leave with a more precise term.
The editorial boundary is deliberate. We do not assign a current schedule, repeat private contact details, or turn a local custom into a universal rule. When the evidence is limited, the page says so and offers a nearby source, such as the source register or the method note.
