This window deals with the history of the Christian Church in America, developed in a series of subject medallions. The theme has been so expressed in the window as to make appropriate the use of other episodes of church history in an adjacent window at some later date.

     The dominant position in the middle lancet is given to Bishop Kemper riding his horse in the West; while below him, John Eliot preaches to the Indians.

     Then, beginning in the lower left medallion are symbolized the Founding of Harvard College, with John Winthrop heading the twelve men of the colony who were its governors. (Seven of the twelve represented are identified as follows: the four at the extreme right, reading from the bottom up are Richard Mather, Richard Bellingham, Joseph Dudley and John Cotton of Boston; those at the left of the table are, reading from left to right, Reverend John Wilson; second, John
Davenport; and fourth, next to John Cotton, is Hugh Peter.)

     Next above, is the Publishing of the Bay Psalm Book - the first book printed in the English Colonies in America. Its authors were John Eliot, Richard Mather, and Thomas Welde (likenesses of John Eliot and Richard Mather). In the medallion background is an early type of printing press.

     At the head of the panel is the Log College for the theological education of boys, erected by William Tennent, Sr.

     Going to the lower right-hand medallion, the Haystack Meeting at Williams College is set forth - the beginning of foreign missions in the United States. (On a hot, sultry afternoon in July or August, 1806, a group of five students, headed by Samuel J. Mills, were driven by a thunderstorm to seek shelter under a haystack, where they talked and prayed together concerning "The Moral Darkness of Asia".

     The middle medallion of this lancet symbolizes the Laying of the Cornerstone of the National Cathedral, by The Right Reverend Henry Yates Satterlee, D.D., LLD., first Bishop of Washington, who holds the trowel and mallet. Taking part in the ceremonial procession are first, the crucifer, followed by several Canons, and the Architect of the Cathedral, Henry Vaughn in academic cap and gown, and other dignitaries. Above is a vision of the facade of Washington Cathedral.

     At the top, the medallion is devoted to Chaplaining of the Armed Forces - the Communion Service (with the soldier in fatigue uniform).

     The uppermost symbol in the design is the Lamp of Faith, surrounded by stars of heavenly steadfastness; while the composition is completed with the text from 1 John 1:3: "Truly our fellowship is with the Father and with His Son Jesus Christ".

     The fields around the medallions are enriched with patterns of oak leaves, symbolizing strength.
     
     Flames in smaller tracery members suggest divine zeal.

     The window is dedicated "To the Glory of God and in Loving Memory of Edyth Penfield Hotchkin".
