You've worked on so many churches. Atmosphere is everything. Light is the most important architectural element. Everybody talks about music in a church, how it can bring a blind person through to a higher place. But lighting is just as powerful.
Good lighting can bring a deaf person through.
I think it was author Brendan Gill who said that light is like the bagpipes. The minute you hear bagpipes, no matter where you are, there is a mystical, physical, and emotional response that occurs. The same thing happens with light. Depends on the day and depends on who's calling.
