The Gustin Window (Benedicite Window), in memory of Jessie McClure Gustin (1872-1947), was given by her daughter, Mrs. Ferguson, and is based on The Book of Common Prayer Canticle, “Benedicite omnia opera Domini” (A Song of Creation) from the Song of the Three Young Men, 35-65, in the Apocrypha (The Book of Common Prayer, p. 47). The eight medallions contain symbols of the cosmic order (water, Sun and Moon, stars, lightning and clouds) and the Earth and its Creatures (mountains and hills, whales, fowls, and human beings).

O ye lightnings and clouds, bless ye the Lord;
Praise him and magnify him for ever.
