The design of the chancel glass, known as the Kaleidoscope Window, is of a quaternity, with four segments of a circle, four ellipses, and four bows at the center, all within a trifoil. The trifoil reminds us of the Trinity, or triune God, embracing a circle, the symbol of wholeness or completeness, and also a figure of the world or created order. The trifoil also appears four times around the perimeter of the circle. The four squares, repeated at the ends of the crossbars, at angles within the large circle, and at the very center of the circle, as well as in doublets within the ellipses, reflect the four Gospels, Matthew, Mark, Luke, and John, and comment again on the wholeness or completeness of the Gospel message. the featherlike indications within the four crossbars may be thought of as pointing everything toward center, and are thus a sign of mystic oneness.

Happily, they also recall the Native American heritage of the island, whose presence first drew a Congregational missionary to these shores. The colors are primarily blue, for God's eternal fidelity, and red, for the shed blood of Christ, against a field of yellow and orange tones denoting the sun, or central light of the universe. The variously spaced red circles within the general filed symbolize the planets and outer galaxies, reminding us of God's everlasting rule through all the expanses of time and space. And the greens and browns intermingled with other, more primary colors reflect the earth itself, and the interweaving of spirit and flesh in the Incarnation. The overall effect of the window is to provide an analytical, geometrical reminder of the Divine Glory as a counterpart to the more romantic, pictorial windows in the rear of the sanctuary.
