During World War II the church named after All Saints located by Grzybowski 3/5 square was included into the area of the ghetto. Inside it – owing to the commitment of father Marceli Godlewski and father Antoni Czarniecki – many people of Jewish origin found a shelter and help.

We shall then quote a fragment of a memoir written by professor Ludwik Hirszfeld Turing his stay in the presbytery: “A sermon. (...) Beautiful and strong were father Godlewski’s words, those of a courageous man. That Homeland is like a Mother. She can hurt you and she can be unjust in her forgetfulness, but you always forgive your Mother, as the Mother craves only for her children’s good. (....) Many people from the district wanted baptism, those older, and those younger, sometimes even the whole families. Among them I saw my pupils, both boys and girls. Not once was I asked to be a godfather. But what would be the motives of those people? As they had no benefits from this, the change of faith did not change their position in the eyes of law. (...) Jews were simply tired of the atmosphere of aversion others felt to them. But for what? It is then my listener standing before me, during her baptism. I see this Jewish nose and trick lips, but her eyes tell me how much she craves for ordinary human liking, which she wants to return with her whole raised heart" (source: "Świadectwo profesora Ludwika Hirszfelda" (en. “The confession of professor Ludwik Hirszfeld”), reprinted from: J. Grzesik "Zagłada Żydów 1939-1945).

Those events have beem commemorated by the plaque placed in the side wall of the church and its inscription: “The Church Named After All Saints commemorates Poles saving Jews in 1939-1945".

A few years ago another commemorative plaque saying about the father Antoni Czarniecki’s actions in occupation was unveiled also inside Saint Catherine's Church in Warsaw.
