After six months illness spent at the home of his father, he was appointed vicar at Horodło, member of the chapter of the collegiate church of the Zamojscy, and later transferred to Tomaszew, which was the scene of great military activity during the Polish uprising of 1863.
Here he fell under the influence of Peter Semenenko, Hieronim Kajsewicz, Aleksander Jełowicki, and Adam Mickiewicz, who dreamed of Poland's resurrection through the spiritual regeneration of the Poles.
Going to Rome, he joined the newly founded Congregation of the Resurrection and soon after receiving the special blessing of Pope Pius IX set out for America (1866).
After several years' labour in the Diocese of San Antonio, Texas, he was appointed pastor of St. Stanislaus Kostka Parish, Chicago, in 1874, then comprising about 450 families.
He gave the American Poles a class consciousness, and took a combative line against the Polish National Alliance.
