St. Agatha Parish exists primarily to serve the spiritual needs of those of the Polish language and ethnicity living in the St. Louis, Missouri area. We live our faith in union with the Supreme Pontiff and the Archbishop of St. Louis. While living in American society, we celebrate our heritage of rich cultural traditions. Through the intercession of Our Lady of Częstochowa, the Queen of Poland, and St. Agatha, the patron of our Parish, we seek to fulfill our calling in Jesus Christ by living out our Catholic faith in love, justice and peace.
