A stained glass window honouring Howard Park United Church parishioners who gave their lives in both World Wars was donated by the War Memorial Committee and unveiled on November 6, 1960. The window was manufactured by Robert McCausland Stained Glass Co. Limited.
The theme of the window is The Resurrection, the triumph of life over death, truth over falsehood, love over hate. In the center is the Risen Christ standing in front of the tomb, symbolized by the mound of rocks in the background. On either side are Roman soldiers in dismay as they behold Christ. On the outside panels are Torches of Peace as found on the Canadian National Vimy Memorial. The names of those who made the supreme sacrifice in the war are inscribed under the torches. Above and on either side are garlands of maple leaves with the inscription in between - "I am the Resurrection and the Life".
At the top of the window, the two Greek letters X P, signify Christ. Next is the burning bush, which is the emblem of the former Presbyterian Church. The descending dove is the emblem of the Methodist Church, signifying the Holy Spirit. The open Bible is the symbol used by the Congregational Church. The Alpha and Omega, the beginning and the ending, signify God. The I.H.S. stands for the Latin words "Iesus Hormonorum Salvitor" which translates to Jesus the Saviour of Men.
At the bottom on the outside panels are the symbols of Valour and Justice. In between, from left to right, are the crests of the Navy, Army, Airforce and Medical Service Corps.
In 1910, the Howard Park Methodist Church moved to a new, partially finished building located at the corner of Sunnyside Avenue and Marmaduke Avenue. In 1925, the church became Howard Park United Church. The congregation remained at this location until 1969, at which time Howard Park united with Emmanuel United Church to form Emmanuel-Howard Park United Church in the Emmanuel building at 240 Roncesvalles Avenue.
The War Memorial Window at Sunnyside Avenue and Marmaduke Avenue was moved to the new building in 1970 by Robert McCausland Limited, Toronto. Panes from the one large stained glass window were made into three smaller windows. In January 2016, the church was renamed Roncesvalles United Church.
