Read the following context and answer the question.
Context: Anyway . In the midst of our circle around the church , the priest finished his sermon and , suddenly , I heard incredible a cappella emanating from somewhere . I thought maybe they had a choir singing up front after the mass , so I rushed past the shuffling crowd to join the tourists at the alter . There was no choir , of course , just a recording echoing around the many nooks and crannies of the cathedral . But , standing there , feeling the light of the stained glass windows wash over me , I really , really was touched .
Question: What may happen while they are at church ?
Answer:


They will practice their religious faith .
