The criteria for the design of the three walls of glass in the Holy Adoration Chapel required that the center window incorporate as its focal point, a place for the Holy Host (see the blue rectangle in the lower part of the center panel.) The window was to be meditative and not distract in any way from the Host. Also required was that the glass create a light filled interior but not be of transparent glass so there would be a feeling of privacy. The wing-like forms of white opal glass suggest the the Holy Spirit, descending as the Dove, and also are meant to hold back the glare of bright light, be uplifting, and provide some color along with the blue opal glass during the evening hours. A crystal cross is above the Host.
