On the right side of the church, the first window is the Baptism by John at the River Jordan, and the story of the Good Samaritan in the bottom pane. The second shows two scenes of the Acts of the Apostles-Pentecost depicted in the upper pane with Peter and John, and John in the lower panel assisting a lame beggar. The third window is the "Resurrection Window" and depicts the discovery of the empty tomb. The fourth window depicts Jesus being removed from the Cross.

The high altar window represents the Ascension with eleven apostles facing Jesus as he ascends to Heaven.

 
St. Barnabas Church Architecture
Architecturally, churches are generally fashioned in the shape of the cross, with the aisle representing pilgrimages or processions leading up to the crossing (in front of pews) and up to the chancel and altar. The nave represents the underside of a boat, when in ancient times religious services were held in the protection of an overturned vessel for shelter and privacy. The eight "ribs" in the ceiling is indicative of the Mayflower Design.

		The lectern, at the end of the aisle on the right next to the Baptismal font, is in the shape of an eagle. This design represents the verses from Isaiah, "Born upon eagle's wings" and "Strength like an eagle." The lessons of the service are read from the lectern and the sermon - or homily - is usually given from the pulpit.
Continuing up to the choir stall and overhead on the ceiling of the chancel are six stenciled designs, attributed to Henry Vaughn, in six repeated patterns: The crown of thorns with three nails in the center; the first three Greek letters of Jesus, "IHC"; the first two Greek letters 'px' of the title Christ (Messiah); pillars with a whip and sword represent Christ being scourged by soldiers (sword); the ladder, reed, sponge, spear and lantern were used at the crucifixion and the purse represents Judah's betrayal; and the cross, hammer, pinchers and pliers were instruments used to secure Christ to the cross.
The blue kneelers at the altar rail have symbols of the altar needlepointed on them.

Memorial Gifts
Many gifts were given to the church in memory of various Beebe family members whose efforts established the parish of St. Barnabas. These gifts include the nine windows, the baptismal font, choir stall, altar rail, pulpit, lectern, communion rail, hymnal board, bishop's chair, church bell (not cast by Paul Revere as is the one across the street at the Congregational Church), organ, chalice, communion service, alms basin, prayer book and painting.

In front of the church and to the left is its rectory. The recently renovated house was formerly owned by Caroline Hatch and sold in 1871 to Robinson Crocker Bodfish. E. Pierson Beebe purchased the house in 1901, had the house restored, and offered to rent it to the parish for $400 per year.

The Parish House and Chapel
Behind the church and to the right is St. Barnabas House. Dedicated in December 1890, it was a gift from Frank Beebe in memory of his mother and two sisters, Frances and Mary Louse. The house was originally used as a reading room or library for the town of Falmouth.

The low wall bordering the western side of the church property was built in 1891 from granite boulders brought from fields near Highfield Hall.

The Chapel The Chapel, located behind the church, was originally a carriage house built in 1894 in memory of Frances Lathrop Beebe Fiske by her children. In 1962 the carriage house was converted into a chapel by William W. and Evelyn Peters as a memorial to his parents. Late afternoon summer services and year-round Wednesday morning services are held in the peaceful chapel.

The Parish Hall, built in 1959, is used for numerous community gatherings by many organizations and houses the Sunday School classrooms and parish offices.
