The eminent Polish musicologist Fr Hieronim Feicht, known for his numerous works on the history of Polish music and publications on old Polish music, was involved in pastoral work four times in his life. At the turn of the year 1932-1933, during the absence of the parish priest, Fr Ludwik Moska, he held the post of house superior and pastor of the parish of St Vincent de Paul in Bydgoszcz. In 1935 he worked for a few months in Łysków. During the occupation he helped with pastoral work in Olcza, near Zakopane. This article, based on the "Chronicle and Announcement Book of the Pastoral Post in Wroclaw on Oporów", presents the work of Father Hieronim Feicht as a pastoral priest for 150 Poles living in Oporów at that time.
