The window takes the life and work of three Redemptorists as its theme, namely Saint John Neumann, The Blessed Kaspar Stanggassinger and the Blessed Peter Donders.
The left panel shows the Blessed Kaspar Stanggassinger teaching a group of German students with the school in the background.
The centre panel shows St John Neumann who was assigned by the Bishop of New York to work with recent German immigrants. He is depicted welcoming a poor family, father, and mother with a child in her arms. St John was consecrated in Baltimore as Bishop of Philadelphia and is shown in vestments. His shrine, is at St. Peter the Apostle Church in Philadelphia. The church depicted at the foot of the panel is St Philomena's Philadelphia, the Cathedral Church where he lived and worked as a Bishop.
The right panel illustrates the Blessed Peter Donders in Dutch Guiana (now the Republic of Suriname), administering to the sick in a leper colony. Native huts and a palm tree form the background, setting the scene and balancing the school in the left panel.
In the tracery above are symbols of sacraments, flanking the figure of Our Lady in the centre.
The new stained glass window was blessed by Archbishop Kelly on Friday the 16th October 2009 - the Feast of St Gerard Majella.
The window has been produced by Pendle Stained Glass Ltd of Padiham, and is composed of Hand –Made Glass throughout.
