"And the Word became flesh and lived among us, and we have seen his glory," writes John the Evangelist. The windows of St. Peter's bear witness to that glory in glass, telling the Christian story in light and color, and surrounding the worship of this community.

Days of Creation
North transept | Genesis 1
This swirling composition reads left to right across the six days of creation. The First Day shows the Spirit of God moving over the waters in the upper left. The Second separates water below from "vapor" above. The Third brings land, sea, and plant life, with volcanic activity at the center. The Fourth adds the sun, moon, and stars. The Fifth fills the window with fish and birds. The Sixth depicts living creatures and humanity, with the hand of God bearing three rays of light to signify the Trinity.

Incarnation
Above the balcony | Isaiah 7:14
Based on Isaiah's prophecy, "Behold, the Virgin shall conceive, and bear a son, and shall call his name Immanuel," the window centers the Christ child with the earth as his footstool and the moon beneath his feet. The "M.R." monogram signifies Maria Regina, Mary the Queen. Twelve stars represent both the tribes of Israel and the Word going forth through the Twelve Apostles. The right-hand light shows the shepherds' crooks, the three crowns of the Magi, and the wallet of their gifts. The left-hand light depicts Isaiah 6:6 — the seraph with a live coal from the altar. Christ is robed in red, signifying his sovereignty as King of Kings.

Resurrection
Over the altar | Revelation 5
The shape of the cross is accented in the predominantly blue background, with the corner panels inscribed ICXC NIKA, "Jesus Christ, Conqueror." At the center, the Agnus Dei holds the Banner of Victory, standing on the closed Book with Seven Seals (Revelation 5). Beneath the Lamb, the open tomb appears with the burial linen draped and the stone rolled away. In the upper panel rises the Phoenix, an ancient symbol of resurrection. To the left and right are the pomegranate and the lily, both traditional resurrection symbols.

New Creation
South transept | Revelation 21–22
This window draws from John's vision of the New Jerusalem. At the top is the morning star (Revelation 22:16), with rays signifying Christ as the Light of the World. Below is the Celestial City coming down out of heaven (Revelation 21:2), set upon an Emerald Rainbow (Revelation 4:3). The River of Life flows from the throne to praying hands at the foot of the window (Revelation 22:1). The Tree of Life encompasses the scene on either side (Revelation 22:2), also intended as the true Vine of John 15. At the perimeter, hands representing "the Peoples of the World" reach in with the chalice, the open Bible, the lighted candle, and praying hands. The Alpha and Omega flank the foot, and the banner reads "Behold, I make all things new" (Revelation 21:5).

The Works of Mercy Windows
Matthew 25:35–36

Three nave windows depict the works of mercy named by Christ in the parable of the sheep and the goats. The first reads "Feed the hungry. Give drink to the thirsty" (Matthew 25:35). The second reads "Shelter the stranger" and "Clothe the naked" (Matthew 25:35–36). The third reads "Visit the sick" and "Visit those in prison" (Matthew 25:36).

The Great Commission Windows
South Transept | Matthew 28:18–20

Two nave windows depict the closing words of Matthew's gospel. The first reads "Go ye therefore and teach all nations" (Matthew 28:18). The second reads "Baptizing them in the name of the Father and of the Son and of the Holy Ghost, lo, I am with you always, even unto the end of the world" (Matthew 28:20).

The Beatitudes Windows
North transept | Matthew 5:3–10

Four windows in the south transept carry the Beatitudes from the Sermon on the Mount, with each window bearing two of the blessings. The first reads "Blessed are the poor in spirit" (Matthew 5:3) and "Blessed are they that mourn" (Matthew 5:4). The second reads "Blessed are the meek" (Matthew 5:5) and "Blessed are they which hunger and thirst after righteousness" (Matthew 5:6). The third reads "Blessed are the merciful" (Matthew 5:7) and "Blessed are the pure in heart" (Matthew 5:8). The fourth reads "Blessed are the peacemakers" (Matthew 5:9) and "Blessed are they which are persecuted for righteousness' sake" (Matthew 5:10).

The St. Peter's Window
Above the entrance

The window above the entrance is the parish's namesake emblem: the crossed keys of Peter, two fish, and an inverted cross. The keys recall Jesus' words to Peter in Matthew 16:19, "I will give you the keys of the kingdom of heaven", and the fish recall Peter's first calling as a fisherman whom Christ would make a fisher of people (Matthew 4:18–19). The inverted cross reflects the early tradition that Peter, considering himself unworthy to die as his Lord did, was crucified upside-down in Rome. It is the smallest of the windows and the one that greets every visitor entering the building.

The windows of St. Peter's were given by parishioners and friends of the parish across the late twentieth century. They were designed by Claude A. Howard, A.M.G.P., and manufactured by J. Wippell & Company Limited of Exeter, England, using 100% European antique glass. The paint pigment was kiln-fired for permanence, and both sides of the leading were fully cemented for waterproofing and additional strength.
