In 1978 Fr. Jerzy Popiełuszko was transferred to the Infant Jesus Parish, in the Żoliborz district of Warsaw, where he taught Religion to children and in extremely adverse housing conditions. Shortly afterwards he was transferred to Res Sacra Miser Chapel in Krakowskie Przedmieście Street in Warsaw, where - to his astonishment - he became a priest of future physicians.
From the university chaplaincy, Fr. Jerzy was nominated for the priest of mid-level medical staff. It was clearly thanks to his efforts, this vital ideological and spiritual community, dangerous to the system, yet of great importance for people, had come into being. The previously mentioned personal qualities of this priest played a vital role in the process. Suffering from overwork with worsening health problems after his military service, Fr. Jerzy collapsed while celebrating Holy Mass in March 1979. After a stay in hospital he was transferred to the Academic Church of St. Anna in Krakowskie Przedmieście Street in Warsaw. His responsibilities were reduced with a view to speed up his recovery, yet they still remained heavy. Due to his experience, Fr. Popiełuszko became responsible for the medical aspect of the approaching pilgrimage of Pope John Paul II to his homeland in 1979. Regular contact with future, also practicing doctors and nurses was an opportunity to organize this community. As is the case, earlier and this time also, owing to his personal qualities, Fr. Popiełuszko quickly gained friendship and trust of the medical staff, who accepted him as their chaplain. Moreover, Fr. Jerzy became involved in the pro-life movement.
