Joseph Ratzinger's theological anthropology critiques the secularization of modern society and its impact on human identity and politics. Rooted in biblical traditions, his perspective contrasts with the classical liberal emphasis on autonomy and individualism. Thinkers like John Locke and Jeremy Bentham advanced concepts of freedom and rationality, but Ratzinger highlights their neglect of humanity's intrinsic relationality and transcendent purpose. For Ratzinger, secularization undermines the foundational role of divine truth in shaping human dignity and societal order. He argues that the liberal anthropological framework, centered on the self-sufficient individual, contributes to cultural fragmentation and moral relativism. In contrast, his anthropology emphasizes the relational nature of humanity, created in dialogue with God. The New Testament, through Jesus Christ, reveals humanity's destiny as beings called to divine communion, offering a vision of dignity grounded in transcendence. Ratzinger's political thought reflects this anthropology, critiquing secular liberalism for failing to provide a cohesive moral framework. He advocates for a political order that recognizes humanity's dependency on divine truth and the centrality of community. By integrating Teilhard de Chardin's cosmic Christology, Ratzinger envisions a society rooted in relationality and oriented toward communion with God, providing a robust foundation for human dignity and justice.
