The windows all have elements that are described in the Canticle:

• Sir Brother Sun is represented by the outer circular lines at the top of each window. The yellow glass helps form the circle and then flows down to the Earth as light.
• Sister Moon and Mother Earth are depicted by the overlapping center circle motif within the yellow of the sun. Sister Moon is the clear portion, and Mother Earth is the brown.
• Brother Wind, represented by both the wispy white glass and flowing lead lines, swirling from heaven to earth.
• Sister Water is the blue glass, falling from the sky as rain and accumulating on earth in the life-giving forms of rivers, lakes, and oceans.
• Brother Fire is represented in the red glass, integrated into the sun motif because it is the light of night.
• Sister Bodily Death is portrayed by the wide, straight lead lines. As horizontal lines below, they portray the inevitability of death. As vertical lines rising up and flowing into and beyond the sun motif, they represent the promise of salvation.
• The Order of Saint Francis is represented by two elements, the brown glass and the thick, curving lead lines. The brown symbolizes the traditional garb worn by the Brothers, and the lead line represents the cord worn around their waist. Both are intimately woven into the other symbols of the Canticle.
