Chapter 7, “Matters of Faith: Catholic Intelligentsia and the Church,” asks how Catholics behaved in Warsaw and why. Roman Catholicism was the religion of the majority of Varsovians and had played an important role in the development of the Polish national project. In the absence of a Polish government, the Church provided a potential locus of authority for Poles. Warsaw’s priests drew particular negative attention from the Nazi occupation for their potential influence and they were viciously persecuted, imprisoned, and often sent to the concentration camp at Dachau. Nevertheless, leaders of the Church, from the pope in Rome to local bishops, were hesitant to provide guidance, support Nazi occupation, or encourage opposition to it. Despite the lack of a top-down Catholic policy, this chapter argues that individual priests and lay Catholic leaders were motivated by their religious faith to form everything from charities to a postwar clerical state. Crucial among Catholics was the question of the developing Holocaust and the role of Polish Jews in Polish Catholic society, which sharply divided them.
