A Theologian Who Understood the Psyche

In the landscape of 20th-century thought, few figures managed to bridge the seemingly disparate worlds of theology, philosophy, and psychology with the elegance and profundity of Paul Tillich. Born in Prussia in 1886 and eventually becoming one of the most influential theologians to grace American academia, Tillich crafted a vision of human existence that speaks directly to the concerns of depth psychology and psychotherapy, often more directly than many explicitly psychological theorists.

For clinicians working with existential distress, meaning-related crises, and the profound anxieties that accompany human existence, Tillich offers not merely intellectual stimulation but genuine therapeutic resources. His concepts of ultimate concern, the courage to be, and ontological anxiety provide frameworks that illuminate the very terrain psychotherapists traverse daily with their clients. Unlike thinkers who remained sequestered within academic abstraction, Tillich engaged directly with the psychological sciences, maintained close friendships with prominent psychotherapists, and deliberately constructed his theological anthropology in dialogue with psychoanalytic insights.

This article explores Tillich’s substantial contributions to our understanding of the human psyche, his direct and indirect influence on depth psychology and psychotherapy, the broader applications of his thought across comparative religion and philosophy, and his continuing relevance for contemporary clinical practice. For therapists seeking to deepen their theoretical foundations or expand their conceptual vocabulary for working with existential and spiritual material, Tillich represents an essential and surprisingly accessible resource.

The Foundations of Tillich’s Thought

Existentialism and the Human Situation

Tillich’s intellectual formation occurred at the confluence of several powerful streams: German idealism (particularly Schelling), Protestant theology, and the emerging existentialist movement. Unlike some existentialists who rejected systematic thinking, Tillich attempted the ambitious project of creating a systematic theology that remained true to existentialist insights about human finitude, freedom, and anxiety.

Central to Tillich’s project was his understanding of the “human situation,” meaning the fundamental conditions of existence that every person confronts simply by virtue of being alive. These include our awareness of our own mortality, our experience of estrangement from ourselves, others, and the ground of our being, and the inescapable necessity of making choices without absolute guarantees. This existential anthropology aligns remarkably well with the concerns of depth psychology, which similarly takes as its starting point the recognition that human beings are not transparent to themselves and must navigate profound uncertainties.

Tillich’s “method of correlation” attempted to bring existentialist analyses of the human situation into dialogue with theological symbols and answers. The questions arise from human existence itself, from our anxiety, our search for meaning, our experience of guilt and estrangement. The answers come from religious symbols, properly interpreted. This method has profound implications for psychotherapy, suggesting that therapeutic work must attend to both dimensions: the existential questions that clients bring and the symbolic resources (religious or otherwise) through which meaning might be discovered or constructed.

Ultimate Concern and the Structure of Faith

Perhaps Tillich’s most famous formulation is his definition of faith as “ultimate concern.” This deceptively simple phrase contains remarkable depth. For Tillich, every human being is structured by concerns. We care about things, we are invested in outcomes, we orient our lives around values and goals. Among these concerns, there is always something that functions as ultimate, something that claims unconditional commitment and promises unconditional fulfillment.

The therapeutic relevance of this concept is immediate. When clients present with symptoms of depression, anxiety, or existential malaise, they are often experiencing a crisis of ultimate concern. Perhaps what they had treated as ultimate has revealed itself as finite and therefore unable to bear the weight of ultimacy. The executive who devoted everything to career success experiences a crisis when professional achievement fails to provide the meaning it promised. The individual who made romantic partnership their ultimate concern faces devastation when that relationship ends or fails to deliver expected fulfillment.

Tillich called this phenomenon “idolatry,” not in a moralistic sense, but in a structural and existential sense. Idolatry occurs when something finite is elevated to ultimate status. Because the finite cannot support infinite demands, idolatry inevitably leads to disappointment and despair. Much of what presents in psychotherapy can be understood through this lens: the client is suffering the consequences of misplaced ultimacy.

Yet Tillich was clear that we cannot simply choose our ultimate concern through an act of will. Ultimate concern is not a belief we adopt but a state of being grasped by something unconditional. This recognition preserves the mystery of transformation that therapists know well, that profound change often occurs not through effort and decision but through being encountered by something that reorganizes the psyche from within.

Anxiety: Ontological and Pathological

Tillich’s analysis of anxiety in The Courage to Be remains one of the most sophisticated treatments of this subject in the literature. Crucially for psychotherapists, Tillich distinguished between existential (or ontological) anxiety and pathological (or neurotic) anxiety.

Existential anxiety is inherent to human existence. It arises from our awareness of our finitude and cannot be eliminated without eliminating consciousness itself. Tillich identified three types of existential anxiety corresponding to three modes of threat to our being:

The first is the anxiety of fate and death, which emerges from our awareness of our contingency and mortality. The second is the anxiety of emptiness and meaninglessness, arising from our awareness of the possibility that our lives might have no significance. The third is the anxiety of guilt and condemnation, stemming from our awareness of our responsibility and our failure to actualize our potential.

These anxieties are not pathological but ontological. They belong to the structure of existence itself. The attempt to eliminate them entirely leads either to neurosis (when they are repressed) or to despair (when they overwhelm the self’s capacity to cope).

Pathological anxiety, by contrast, arises when existential anxiety is not faced and integrated but rather avoided through neurotic mechanisms. The person who cannot acknowledge their mortality may develop obsessive rituals designed to create an illusion of control. The individual who cannot face meaninglessness may grasp desperately at pseudo-meanings that inevitably disappoint. When existential anxiety is repressed, it does not disappear but transforms into neurotic symptoms.

This distinction has profound implications for psychotherapy. It suggests that the therapeutic goal cannot be the elimination of anxiety, for such a goal would be both impossible and undesirable. Rather, therapy aims to transform the client’s relationship to anxiety, helping them face existential anxiety with courage while resolving the neurotic patterns that arise from avoidance. The therapist who understands this distinction will not attempt to reassure clients out of their awareness of mortality or meaninglessness but will instead help them develop what Tillich called “the courage to be.”

Tillich’s Direct Engagement with Depth Psychology

Dialogue with Psychoanalysis

Tillich was not merely a theologian who happened to have interesting things to say about psychology. He actively engaged with psychoanalytic thought throughout his career and saw significant convergence between depth psychology and his own theological anthropology.

Tillich recognized in psychoanalysis, particularly in its attention to unconscious processes, its appreciation of symbolic meaning, and its understanding of human self-deception, a powerful resource for understanding the human condition. He saw Freud’s discovery of the unconscious as having profound theological significance, revealing that human beings are not masters in their own house and that much of what drives behavior occurs beneath the threshold of awareness.

Yet Tillich was also critical of certain tendencies within psychoanalysis, particularly its reductionism regarding religious experience. Where Freud saw religion primarily as illusion or projection, Tillich insisted that religious symbols, properly understood, point to genuine dimensions of reality. The therapeutic task is not to eliminate religious concern but to purify it of idolatrous distortions.

Tillich’s essay “The Theological Significance of Existentialism and Psychoanalysis” explicitly addressed these connections. He argued that existentialism and psychoanalysis share a common recognition of human estrangement, the fact that human beings are separated from their essential nature, from other beings, and from the ground of being itself. Psychoanalysis describes this estrangement in terms of repression, conflict, and neurosis. Existentialism describes it in terms of inauthenticity, anxiety, and despair. Theology describes it in terms of sin and separation from God. These are not competing descriptions but complementary perspectives on the same human reality.

Collaboration with Rollo May

Tillich’s most significant engagement with psychotherapy came through his close friendship with Rollo May, the pioneering existential psychologist. May studied with Tillich at Union Theological Seminary in the 1930s, and Tillich served as May’s doctoral advisor when May completed his Ph.D. in clinical psychology at Columbia University in 1949. Their relationship profoundly shaped May’s development as a thinker and clinician.

May dedicated his influential work The Courage to Create to Tillich, and his earlier The Meaning of Anxiety drew extensively on Tillichian concepts. The very notion that anxiety could be approached not merely as a symptom to be eliminated but as a revealing dimension of human existence, this insight so central to existential psychotherapy owes much to Tillich’s influence on May.

The two engaged in ongoing dialogue about the nature of anxiety, the structure of the self, and the relationship between psychological and religious dimensions of human existence. May brought clinical experience and psychological sophistication to the conversation while Tillich contributed philosophical depth and theological perspective. The result was a mutually enriching exchange that helped establish existential psychotherapy as a significant movement.

May would later write extensively about how Tillich’s concept of courage as self-affirmation despite non-being provided the foundation for his own clinical approach. When clients face their fears, acknowledge their finitude, and affirm themselves in the face of anxiety, they are enacting what Tillich described as the courage to be.

Contributions to Pastoral Counseling

Tillich’s influence on pastoral counseling and the broader field of psychology and religion has been substantial. His insistence that theological language, properly interpreted, addresses genuine human needs provided theoretical justification for the integration of psychological and spiritual approaches to healing.

Tillich’s distinction between technical reason (which deals with means) and ontological reason (which grasps being itself) helped pastoral counselors understand their distinctive contribution. While psychotherapy in its technical dimensions addresses symptoms and facilitates adjustment, pastoral work addresses the deeper questions of meaning, ultimate concern, and relationship to the ground of being. These are not competing but complementary functions.

Moreover, Tillich’s Protestant principle, his insistence that no finite form can be identified absolutely with the ultimate, provided resources for pastoral counselors working with clients whose religious life had become rigid, idolatrous, or pathogenic. The goal of pastoral work is not to reinforce religious belief but to facilitate an authentic relationship to ultimate concern, which may require the therapeutic breakdown of religious forms that have become obstacles to genuine faith.

The Courage to Be: Therapeutic Implications

Self-Affirmation Despite Non-Being

Tillich’s concept of courage deserves extended attention for its therapeutic relevance. In The Courage to Be, Tillich defines courage as “the self-affirmation of being in spite of the fact of non-being.” This is not courage in the ordinary sense of bravery in facing external dangers but rather the ontological courage required simply to exist as a finite being aware of its own finitude.

The threats of non-being, including death, meaninglessness, and condemnation, are not external threats that we might avoid with sufficient caution. They are intrinsic to existence itself. The courage to be is the courage to affirm oneself despite the constant presence of these threats, to say yes to life knowing that life includes suffering, ends in death, and may have no cosmic significance.

For psychotherapy, this concept illuminates the goal of treatment in existential terms. We are not trying to help clients avoid anxiety or escape their human condition. We are trying to help them develop the courage to face that condition honestly and affirm themselves within it. The client who can acknowledge mortality without paralysis, face uncertainty without despair, and accept responsibility without self-destruction has developed the courage to be.

Tillich distinguished three types of courage corresponding to the three types of existential anxiety. Stoic courage is the courage to accept fate and death with equanimity. Creative courage is the courage to create meaning despite the possibility of meaninglessness. Mystical courage is the courage to accept acceptance despite guilt.

These correspond roughly to different therapeutic emphases: helping clients accept what cannot be changed, supporting creative engagement with life, and facilitating self-compassion and acceptance of human imperfection.

The Courage to Be as a Part and the Courage to Be as Oneself

Tillich identified two one-sided forms of courage that appear throughout history and in individual psychology. The courage to be as a part involves affirming oneself through participation in a larger whole, such as a community, tradition, movement, or relationship. The courage to be as oneself involves affirming one’s individual uniqueness, standing alone if necessary against collective pressures.

Neither form of courage is adequate by itself. Pure collectivism dissolves individual identity while pure individualism leads to isolation and emptiness. Health requires a dialectical courage that includes both participation and individuation.

Therapists will recognize this dialectic in their work. Some clients have lost themselves in their relationships, roles, or group identities. They have the courage to be as a part but lack the courage to be as themselves. They need therapeutic support for individuation, differentiation, and the development of authentic selfhood. Other clients have isolated themselves, rejected connection, and made autonomy an idol. They have the courage to be as themselves but lack the courage to be as a part. They need help developing capacity for intimacy, belonging, and participation in something larger than the isolated ego.

Absolute Faith and the God Above God

In the final and most challenging chapter of The Courage to Be, Tillich describes what he calls “absolute faith,” a courage that transcends both collectivism and individualism and remains possible even when both traditional theism and secular meaning-systems have collapsed.

This is the courage that persists when the symbols that previously mediated meaning have become empty, when neither belonging nor autonomy provides sufficient ground for self-affirmation. Tillich associates this courage with what he provocatively calls “the God above God,” a ground of being that transcends the theistic God who is merely one being among others.

While this might seem abstract, it has clinical relevance for work with clients in profound existential crisis, those experiencing what Tillich called “the boundary situation” where all finite sources of meaning have failed. Such clients cannot be helped by being given new beliefs to hold or new groups to join. They need to discover a ground of courage that lies beneath all particular contents, what Tillich described as being grasped by the power of being itself.

This is delicate clinical territory, and Tillich would not claim that theology can prescribe what happens in such moments. But he provides conceptual resources for understanding and supporting clients who are navigating the darkest passages of existential despair.

Tillich in Comparative Religion and Philosophy

Influence on Religious Studies

Tillich’s impact extends far beyond Christian theology into the broader academic study of religion. His concept of religion as ultimate concern provided a functional definition that allowed for cross-cultural comparison without privileging any particular tradition. Rather than defining religion in terms of belief in God or adherence to supernatural claims, Tillich’s definition located religiousness in the structure of human existence itself, in our capacity to be concerned ultimately about something.

This approach influenced generations of scholars in comparative religion. It suggested that secular ideologies could function religiously (when they became objects of ultimate concern) and that ostensibly religious practices might not be truly religious (if they lacked the character of ultimate commitment). The category of “quasi-religion” that Tillich developed, applying to nationalism, communism, and other secular movements that demanded absolute devotion, proved particularly useful for understanding 20th-century political phenomena.

Mircea Eliade, though working from different premises, found in Tillich a conversation partner for developing the phenomenological study of religion. Both thinkers insisted on taking religious symbols seriously as meaningful in themselves, not merely as symptoms of psychological or social processes to be explained away.

Philosophy of Religion and Theology of Culture

In philosophy of religion, Tillich’s work remains influential for its sophisticated treatment of religious language and symbols. His theory of religious symbols, arguing that symbols participate in the reality they symbolize, open up dimensions of reality otherwise closed to us, and cannot be replaced by arbitrary signs, provided resources for defending the cognitive significance of religious discourse against positivist critiques.

Tillich’s theology of culture extended religious analysis to all dimensions of human creativity. Art, politics, science, and economics all express an underlying spiritual substance, a relationship to ultimate concern that can be discerned by proper analysis. This approach influenced cultural criticism and the developing field of religion and culture studies.

For therapists, Tillich’s cultural theology provides resources for understanding clients’ relationship to their cultural context. The spiritual emptiness that many clients experience is not merely individual pathology but reflects broader cultural conditions, what Tillich diagnosed as the loss of “depth” in contemporary culture.

Existentialist Philosophy

Within the broader existentialist movement, Tillich occupies a distinctive position. Unlike Sartre, who insisted on the atheistic implications of existentialism, Tillich demonstrated that existentialist insights could be integrated with religious faith. Indeed, religious symbols properly understood express existential truth.

Tillich engaged seriously with Heidegger, whose analysis of being-toward-death and authentic existence profoundly influenced his own thinking. Yet Tillich criticized Heidegger for failing to move from ontological analysis to explicit religious affirmation. The “call of conscience” that Heidegger described, Tillich argued, is ultimately the call of being itself. The call to authentic existence is a religious call whether or not it is recognized as such.

For therapists working with existential themes, Tillich provides a version of existentialism that remains open to transcendence without requiring adherence to traditional religious doctrines. This makes his thought particularly useful for work with clients who are spiritual but not religious or who are in transition between religious frameworks.

Tillich’s Relevance for Contemporary Psychotherapy

Meaning, Purpose, and Existential Crisis

Contemporary psychotherapy increasingly recognizes the importance of meaning and purpose for psychological well-being. Research by psychologists such as Michael Steger has documented the strong correlation between meaning in life and positive mental health outcomes. Viktor Frankl’s logotherapy, focused explicitly on the search for meaning, has experienced renewed interest.

Tillich’s work anticipates and deepens these developments. His analysis of meaninglessness as one of three fundamental anxieties places meaning-related distress within a comprehensive existential framework. His concept of ultimate concern provides a sophisticated vocabulary for exploring what matters most to clients and whether their lives are oriented around concerns adequate to bear the weight they place upon them.

For therapists working with clients in existential crisis, Tillich offers several valuable resources. First, he normalizes the experience of meaninglessness as an inherent possibility of human existence rather than a symptom of individual pathology. Second, he provides conceptual tools for distinguishing between genuine engagement with meaninglessness and neurotic avoidance of the question. Third, he points toward resolution not through intellectual answers but through experiential encounter with what he called the power of being.

Integration of Spiritual and Psychological Perspectives

The contemporary mental health field increasingly recognizes the importance of addressing spiritual concerns in therapy. Research consistently shows that spirituality and religion are significant factors in many clients’ lives and that attending to these dimensions improves treatment outcomes.

Yet many therapists feel ill-equipped to work with spiritual material, uncertain how to integrate it with their psychological training. Tillich’s work provides a bridge. His translation of theological concepts into existential terms makes religious ideas accessible without requiring confessional commitment. His critique of literalism and idolatry provides resources for working with problematic forms of religiosity. His insistence on the depth dimension of all human experience suggests that spiritual concerns are never truly separate from psychological concerns.

Therapists influenced by Tillich can engage spiritual material neither dismissively (reducing it to pathology) nor uncritically (accepting every religious claim at face value). They can help clients examine their ultimate concerns, identify idolatrous patterns, and move toward more authentic relationships to transcendence.

Anxiety, Acceptance, and Transformation

Contemporary approaches such as Acceptance and Commitment Therapy (ACT) emphasize acceptance of difficult internal experiences rather than attempts to eliminate them. This represents a significant shift from earlier behavioral approaches that focused primarily on symptom reduction.

Tillich anticipated this development by decades. His distinction between existential and pathological anxiety implies that the therapeutic goal cannot be anxiety elimination but must involve transformed relationship to anxiety. His concept of “the courage to be” describes precisely the acceptance of existential realities (including anxiety) that ACT and related approaches cultivate.

Yet Tillich adds something that purely psychological approaches often lack: a framework for understanding what makes acceptance possible. For Tillich, the courage to accept anxiety is finally grounded in being grasped by the power of being itself. Acceptance is not a technique to be mastered but a grace to be received. This insight may help therapists understand why acceptance proves so difficult for some clients and what deeper resources might need to be activated for transformation to occur.

Psychotherapists Influenced by Paul Tillich

Paul Tillich’s impact on psychotherapy extends through numerous clinicians and theorists who drew directly from his work or developed their approaches in dialogue with his ideas.

Rollo May stands as the most prominent psychotherapist shaped by Tillich. As Tillich’s student and advisee, May integrated Tillichian concepts into the foundation of American existential psychology. His books including The Meaning of Anxiety, Love and Will, The Courage to Create, and Existence (co-edited with Ernest Angel and Henri Ellenberger) all bear Tillich’s influence. May’s therapeutic approach emphasized helping clients confront anxiety, develop courage, and engage creatively with existence.

Carl Rogers, while developing person-centered therapy from different intellectual sources, engaged with Tillich in public dialogue. Their famous 1965 conversation explored the relationship between theology and therapy, and Rogers acknowledged points of convergence between his concept of unconditional positive regard and Tillich’s understanding of acceptance.

Irvin Yalom, a leading figure in existential psychotherapy, draws on the tradition that Tillich helped establish. Yalom’s identification of four ultimate concerns (death, freedom, isolation, and meaninglessness) echoes Tillich’s existential analysis, and his therapeutic approach reflects the Tillichian emphasis on confronting rather than avoiding existential anxiety.

James Hillman, founder of archetypal psychology, studied at the Jung Institute but engaged seriously with Tillich’s thought. His emphasis on soul-making and his critique of literalistic approaches to both psychology and religion reflect Tillichian themes.

Kirk Schneider, a contemporary existential-humanistic psychologist, explicitly acknowledges Tillich’s influence on his work. His concept of “awe-based therapy” and his emphasis on the polarities of human existence draw on Tillichian categories.

Seward Hiltner, a pioneer of pastoral psychology and counseling, developed his approach in direct conversation with Tillich at the University of Chicago. Hiltner’s integration of psychological and theological perspectives in pastoral care owes much to Tillich’s model.

Howard Clinebell, another major figure in pastoral counseling, built on Tillichian foundations in developing growth-centered approaches to pastoral psychotherapy. His emphasis on the spiritual dimension of wholeness reflects Tillich’s influence.

Viktor Frankl, while developing logotherapy independently, shares significant common ground with Tillich in their mutual emphasis on meaning as central to human existence and their recognition of the spiritual dimension of psychological distress. Both thinkers were working through existentialist frameworks to address the crisis of meaning in modern culture.

The broader movements of existential psychotherapy and humanistic psychology that emerged in the mid-20th century were shaped by the intellectual climate that Tillich helped create. His insistence on taking seriously the depth dimension of human existence, his sophisticated treatment of anxiety and courage, and his integration of psychological and spiritual perspectives all contributed to making space for therapeutic approaches that transcended both reductive behaviorism and orthodox psychoanalysis.

The Continuing Gift of Tillich

Paul Tillich offers contemporary psychotherapy something increasingly rare: a comprehensive vision of human existence that integrates psychological, philosophical, and spiritual dimensions without reducing any to the others. In an age of specialization and fragmentation, his synthetic achievement provides resources for therapists seeking deeper foundations for their work.

For depth psychology specifically, Tillich remains remarkably relevant. His existential analysis of anxiety speaks directly to what clients bring into the consulting room. His concept of ultimate concern provides a framework for exploring the deepest motivations and commitments that shape human lives. His understanding of symbols and their participation in the realities they represent offers resources for working with dreams, images, and the productions of the unconscious.

Beyond technique, Tillich offers therapists a way of understanding their vocation. The courage to be, which therapy aims to cultivate in clients, must also characterize the therapist. To sit with another person in their anxiety, their despair, their search for meaning, requires a courage that is finally ontological rather than merely professional. Tillich helps us understand what we are doing in the therapeutic encounter and why it matters.

As clients continue to present with meaning-related distress, existential anxiety, and spiritual struggles, Tillich’s thought remains not a historical curiosity but a living resource. His work invites therapists to recognize the depth dimension of all psychological distress and to approach that depth with the courage, wisdom, and reverence it deserves.
