Paul Tillich

Paul Tillich was the theologian who made God thinkable for people who could no longer believe in God — a philosopher-theologian whose radical reinterpretation of Christian faith in terms borrowed from existentialism, psychoanalysis, and the philosophy of culture made him the most important bridge between Christianity and modern secular thought in the twentieth century. His concept of God as “the ground of being” — not a supernatural person who exists somewhere above the world but the infinite depth and source of all existence — allowed intellectuals who had rejected the God of traditional theism to take seriously the questions that religion addresses: the meaning of existence, the reality of death, the nature of courage, and the possibility of grace. For two decades, from the late 1940s to the mid-1960s, Tillich was the most famous theologian in America — he appeared on the cover of Time magazine, lectured to packed auditoriums, and served as a kind of spiritual counsellor to the educated American public.

Starzeddel and Weimar

Paul Johannes Tillich was born in 1886 in Starzeddel, Brandenburg (now in Poland), the son of a Lutheran pastor. He studied theology and philosophy at the universities of Berlin, Tübingen, Breslau, and Halle, earning his doctorate in philosophy in 1911. He served as a military chaplain in the German army during World War I — an experience that shattered his earlier idealism and brought him face to face with the reality of death, despair, and the collapse of the cultural certainties of bourgeois Protestantism.

In the Weimar Republic, Tillich became a leading figure in the religious socialist movement, arguing that Christianity required a critique of capitalism and that socialism needed a spiritual dimension. He taught at Marburg, Dresden, Leipzig, and finally Frankfurt, where he was professor of philosophy when the Nazis came to power. He was one of the first non-Jewish professors dismissed by the Nazi regime (1933), and he emigrated to the United States at the invitation of Reinhold Niebuhr.

America

Tillich joined the faculty of Union Theological Seminary in New York, where he taught from 1933 to 1955. He later held positions at Harvard (1955–1962) and the University of Chicago (1962–1965). His English was initially halting, but he gradually mastered the language and developed a style — dense, paradoxical, and intensely serious — that became recognisable and influential.

The Courage to Be

The Courage to Be (1952) was Tillich’s most popular and most accessible book — a philosophical and theological analysis of anxiety and courage that drew on Kierkegaard, Heidegger, and Freud. Tillich distinguished three types of anxiety — the anxiety of death, the anxiety of meaninglessness, and the anxiety of guilt — and argued that genuine courage is not the absence of anxiety but the affirmation of being in spite of anxiety. The concept of “the God above God” — the ground of being that remains when all conventional images of God have been destroyed by doubt — was the book’s most radical and most influential idea.

Systematic Theology

Systematic Theology (3 volumes, 1951–1963) was Tillich’s masterwork — a comprehensive restatement of Christian theology using his “method of correlation,” in which the existential questions posed by human experience (finitude, estrangement, ambiguity) are correlated with the theological answers provided by Christian revelation (God as ground of being, Christ as the New Being, the Spirit as the presence of the divine in culture). The system was ambitious, rigorous, and frequently obscure — professional theologians have debated its coherence ever since — but its central insight, that theology must address the actual spiritual situation of modern humanity rather than repeat the formulas of the past, has been widely accepted.

The Sermons

Tillich’s three volumes of sermons — The Shaking of the Foundations (1948), The New Being (1955), and The Eternal Now (1963) — were his most widely read works and reached an audience far beyond the academy. The sermons applied his philosophical theology to the everyday experiences of modern life — loneliness, doubt, suffering, grace — with a directness and emotional power that made them accessible to readers who could not follow the arguments of Systematic Theology.

The Private Life and the Question of Authenticity

Tillich’s posthumous reputation was complicated by the revelation, in his widow Hannah Tillich’s memoir From Time to Time (1973), of a private life that stood in sharp contrast to his public image as a spiritual guide. Hannah described a marriage marked by serial infidelity, pornography, and emotional manipulation — a portrait that shocked Tillich’s admirers and raised uncomfortable questions about the relationship between a thinker’s ideas and his personal conduct. The revelations did not invalidate Tillich’s theology — The Courage to Be does not become less penetrating because its author was less courageous in his personal life than his readers assumed — but they added an ironic dimension to his concept of “estrangement,” the existential condition of being separated from one’s authentic self. Tillich understood estrangement philosophically because he experienced it personally.

Legacy and Influence

Tillich’s influence has been both enormous and curiously diffuse. He shaped the vocabulary of American liberal Protestantism — “ultimate concern,” “ground of being,” “New Being,” “the courage to be” — in ways that persist even among people who have never read his works. His attempt to correlate theology with culture influenced a generation of theologians, from Langdon Gilkey to David Tracy. His impact extended beyond theology into psychology (Rollo May was a student and friend), art criticism (On Art and Architecture was published posthumously), and the broader cultural conversation about the meaning of faith in a secular age. His standing among professional theologians has declined since the 1970s, partly because his system is seen as too dependent on existentialist categories that have themselves dated, and partly because liberation theology, feminist theology, and postmodern theology raised questions — about power, gender, and particularity — that Tillich’s abstract, universalising framework could not easily accommodate. But The Courage to Be endures as one of the essential texts of twentieth-century religious thought.

Collecting Tillich

The Courage to Be (Yale University Press, 1952) is the most collected and most accessible title. Systematic Theology (University of Chicago Press, 1951–1963, 3 volumes) is the magnum opus. The Shaking of the Foundations (Scribner’s, 1948) is the first sermon collection. The Socialist Decision (first German edition, 1933; English translation, Harper & Row, 1977) is the early political work. Tillich’s books were published by academic and religious presses; first editions are generally available.
