In the sanctuary skylight, a large circular stained-glass window portrays
the Holy Spirit of God descending in a stream of light surrounded by heads
of winged cherubs. The vaulted skylight is surrounded by four ornamental
medallions: the liturgical symbols of the Bible, the Keys of God's Kingdom;
the Cross of Christ; the Crown of Glory; and the fleur-de-lis, a symbol of
the Blessed Virgin Mary.
