The act of entering a church was important to Saarinen as well, so the environment changes to reflect the change of attitude one has when entering a sacred space. The grey slate floors, dark mahogany pews, and eerie natural lighting instill a sense of awe in the visitor. The primary light source into the sanctuary is the oculus at the base of the spire, directly above the Communion table. This focus of light draws attention to the center of the room, where the Communion takes place.
