The "stained glass" windows were designed and fabricated specifically for the new church by Kenneth F. vonRoenn, Jr. of Architectural Glass of Louisville, Kentucky.

The Pastor, in consultation with the members of the Art and Environment Committee and parish members, worked closely with vonRoenn and gave him the direction to give a modern interpretation to traditional expressions of the faith and to also give a sense of our local environment, the prairie.

	The south windows behind the altar call to mind creation, with the blue sky and sea, combined with the natural elements of our native Illinois and Midwestern prairie states.
	The clerestory windows above the altar and around the church are shaped like the Tau Cross, an Old Testament cross which signifies prophecy and anticipation and mark a person or place as consecrated to the Lord. The coloring chosen for these windows reflects the movement of the sun to the best advantage.
	The two long angel windows on the right and left sides of the church are in deep solid colors. Both angels are depicted with broken chains, symbolizing St. Peter's release from prison by an angel (Acts 12:7-10). The west angel is depicted as feminine, the east angel as masculine.
	The Crucifixion/Resurrection window located above the entrance to the narthex uses a special photographic process developed by vonRoenn. During daylight hours, the figure of the crucified Christ is evident. When it is dark outside, the image of the Risen Christ can be seen.
	The four long windows to the side of the day chapel use the same photographic process. The Four Evangelists, Matthew, Mark, Luke and John, are depicted in these windows. These images are taken from statues at the ancient Cathedral at Chartre, France.
	On the east wall, four female saints are depicted, again from statuary at Chartre Cathedral. The artist tells us that these figures are shown in negative order to contrast with the figures on the opposite wall and to use the light from the morning sun to advantage. The saints are St. Juliana, (c. 305) binding a winged devil with a chain; St. Gertrude of Nevelles, (c. 659) patroness of travelers and gardeners, who died on March 17th and is connected with the mission of St. Patrick; St. Walburga, ( c. 779) Benedictine Abbess shown holding a vial of miraculous oil said to cure people; and St. Euphrasia, (c. 120) nun known for her austerities and humility.

With the exception of the angel windows and the Crucifixion/Resurrection window, all of the windows use prismed glass to reflect the light. This includes the plain glass windows that separate the nave from the narthex.

The rest of the natural lighting for the church comes from the glass block windows and the large glass windows at the pinnacle of the roof over the altar.
