The proper lighting is a source 4/ellipsoidal light. This is the type of light that has a great deal of focusing flexibility.
Also - to address the question of how they do it in TV/Conference center lighting - they do dim the choir, rostrum, and first few rows then have several very carefully focused lights on the speaker from lots of angles. The dimmed area is not totally dark, though. The rest of the 'dimming' is achieved through camera settings - which I'm not totally familiar with - but I think it's mostly a contrast setting.
To achieve this type of effect would require a HUGE investment in terms of time and money in a chapel, and would result in some pretty ugly wall/ceiling warts. I don't deny there is a problem in many buildings, but I'm not sure adding this type of lighting is the best solution.
