The church includes a Casavant Frères Pipe Organ (Opus 3650, 1988), situated at the back of the gallery under a large west-end rose window.

Considerable tonal variety is available on the three manual divisions and pedal and includes appropriate divisional choruses that are balanced individually and are structured to work together in the ensemble of the instrument as a whole.

While this instrument speaks with a decidedly French accent, it has proven extremely effective in presenting the music of Bach and his contemporaries and in accompanying the singing of the congregation and choirs of the parish.

In the year 1928, a new Polish parish was established on Farmington Avenue in the City of New Britain, Connecticut under the leadership of Rev.

That same year, eight Sisters of St. Joseph, Third Order of St. Francis were asked to teach the Polish language and religion to the children of the newly founded parish after school hours.
