The wooden sculpture spanning the south wall mirrors the overall architectural design of the church campus: progressing from west to east and building out and up as it leads from the educational and community spaces in the Parish Center through the worship space of the nave and then up to heaven. Vertical stripes of natural wood alternate on a red background which recalls the tongues of fire of the Holy Spirit on Pentecost (50th day, or seventh Sunday, after Easter). Cutouts highlight the Crucifix as well as a statue located behind the chapel altar.
The wall behind the main altar shows the original brickwork of the church interior. The white dove recalls the descent of the Holy Spirit at the Baptism of the Lord (first Sunday after January 6); and seven droplets (which some interpret as representing Baptism, the Passion, and/or tongues of fire from Pentecost) recall the seven traditional gifts of the Holy Spirit: Wisdom, Understanding, Counsel, Fortitude, Knowledge, Piety, and Fear of the Lord.
