THEOREM Explained: A Mystical Treatise on the Essence of Life

Born in Bologna, the director left behind around twenty feature films, many of which have become permanent fixtures in the history of cinema. Among Pasolini’s numerous important cinematic achievements, I consider the film that marks its 56th anniversary this year to be his most perfect work. On this occasion, I decided to explore the significance of one of the greatest philosophical treatises ever captured on film, and the pinnacle of Pasolini’s humanistic thought – Theorem.

The Gospel According to Pier Paolo

The term “theorem” in logic refers to a proposition derived from previously existing and accepted statements.

It is thus a derivative of a set of propositions (prior theorems or axioms) that form a system within which the new proposition exists. The etymology of this Latin-Italian term traces back to the Greek theorema, which, besides its logical meaning, also conveys the ideas of “spectacle” and “intuition.” It seems that all three categories suggested by the title are reflected in the film. Theorem is indeed a film—a kind of spectacle or show—where religious reflection and a form of theological deduction intertwine with intuitionism, giving cognitive primacy to non-verbal, sensory perception.

The story Pasolini tells in Theorem is spare and brilliantly simple—a mysterious, unnamed Guest arrives at the home of a wealthy Italian family. He intrigues them with his sensual confidence, wise and penetrating gaze, and the mere fact of being an Outsider, someone from the outside. Played by Terence Stamp, the man gradually seduces all the household members: the maid (Emilia), the son (Pietro), the mother (Lucia), the daughter (Odetta), and the father (Paolo). However, when the head of the family, the last to succumb to his charm, finally does, the Guest departs just as silently and without explanation as he arrived. His disappearance leaves a void in the family’s life that each member tries to cope with in their own way.

The sequences of seduction and the struggles with the Guest’s departure constitute the two fundamental parts of Theorem —the moment of Presence and the confrontation with the Void, connected by transitional farewell scenes. Before we witness the course of the fateful visit, Pasolini shows us a quasi-documentary scene of interviews with the factory workers managed by Paolo (as we later learn, this was actually the epilogue of the whole story), and sepia-toned scenes presenting the family members, signaling their characters and personality traits. Color appears only when the father reads a brief telegram brought by a cheerful messenger: “I’m arriving tomorrow.” From this moment on, the gray, monochromatic overlay and documentary style disappear, replaced by the restrained yet carefully composed frames characteristic of Pasolini’s cinema, colored with vivid, expressive hues.

The Guest’s name remains unknown, as does his relationship with the family that entitles him to sudden and authoritative visits. His identity can only be inferred from the context—the Guest is God Himself. However, this is not the God preached by priests, nor does He seem to belong to any earthly religious institution. The mysterious, laconic Guest is more a vital force, divine energy clothed in human form than a personal Creator known from catechism. By using direct quotes from the Bible and transforming religious symbolism, Pasolini creates in Theorem something akin to a personal spiritual impression, a kind of personal Gospel in which he tries to understand and describe the absolute through his own sensitivity.

It is no surprise that the Vatican reacted sharply after the film’s premiere, deeming it blasphemous and sacrilegious.

The Prophet Pasolini

Theorem is Pasolini’s sixth feature film—roughly in the middle of his career, which spanned from 1961 to 1975. By the time of its release, Pier Paolo Pasolini was already an acclaimed filmmaker with at least three significant works to his credit (Accattone, Mamma Roma, and The Gospel According to St. Matthew). From the very beginning of his career, the director was recognized as a highly intellectual artist, using the language of cinema in a very deliberate way.

His uniqueness on the map of Italian cinema of the time lay in his skillful and sometimes surprising combination of poeticism with the socialist zeal of his films. Pasolini’s sensibility was deeply rooted in both Marxism and Catholicism, from which emerged a specific existential fatalism in his portrayal of the world, as well as a dual revolutionary potential. Concerning the conservatism of post-war Italy, Pasolini was a revolutionary, sharply attacking class inequalities and the rigid institutions oppressing the working class. On the other hand, from the perspective of leftist orthodoxy, the creator of Salò appeared as a spirituality-obsessed intellectual whose theological-historical inquiries had little to do with the ideas of global proletarian revolution. The result was a deep anti-orthodoxy in Pasolini, who seemed to break both the frameworks of tradition and revolutionary thought.

This dialectic was reflected in the creator’s approach to sexuality, suspended between contradictions and the classical understanding of it. On one hand, depicting the social problems of the poor and undertaking a sharp cultural critique, Pasolini drew attention to the issue of prostitution, explicitly pointing to sex as a tool of male dominance and class oppression. However, sexuality is also, for him, a form of vital energy, oppressed by cultural institutions of life force and affirmation of existence. This resulting ambivalence gives Pasolini’s work a dark, provocative flavor, making his films continually elude clear-cut interpretations. Considering Theorem as the pinnacle of the Italian master’s anthropological thought, I believe he comprehensively combined in this work the three outlined threads and perspectives, illustrating the meanings that emerged at their intersection in the most nuanced way.

In Theorem, the three Pasolinis—Pasolini the mystic, Pasolini the provocateur, and Pasolini the revolutionary—came equally to the fore. It was from these three identities that the God-Guest was born.

Divine Presence

The mystical and theological dimension of the film forms its framework, organizing the entire narrative. Before Theorem, Pasolini twice attempted to delve into the mystery of past spirituality, examining the early Christian figure of Christ in The Gospel According to St. Matthew and the ancient pagan mysticism of action and destiny in Oedipus Rex.

In Theorem, he examines contemporary spirituality, proposing a synthetic vision of God and faith. The director does not hide the religious tone of the film, opening its main part with a quote from the Book of Exodus: So God led the people around by the desert road… (Ex 13:18), read against the backdrop of the volcanic wasteland of Etna, which will recur as a vision interrupting the main course of events. The barrenness and emptiness, creating the need for divine guidance, serve as the backdrop for the Guest’s visit, whose arrival brings color to the gray existence of the family. During his Presence, the character played by Terence Stamp reveals discreet similarities to Jesus—his facial expressions, as he looks benevolently at the family members trying to please him, occasionally resemble the gentle gazes of crucified Christ’s images, and his power goes beyond seductive charm, allowing him to sense the emotions and intentions of others and even heal the father, suddenly struck by illness.

However, the Guest primarily gives meaning to the lives of the family members, liberating them and unleashing their repressed elements. In this sense, the metaphysical vitality he embodies becomes the impulse that gives significance to human life, hitherto engulfed in lethargy and stagnation.

The suggestions regarding the Guest’s divine identity culminate in the quote from the Book of Jeremiah that concludes the Presence part: You deceived me, Lord, and I was deceived; you overpowered me and prevailed. I am ridiculed all day long; everyone mocks me. … All my friends are waiting for me to slip, saying, ‘Perhaps he will be deceived; then we will prevail over him and take our revenge on him (Jer 20:7–10). At this point, it becomes clear who the Guest is, or at least what role he played in the family’s life. However, the divine breath they experienced also carries danger. You came here to destroy, the father will say in farewell to the unnamed man. For after his departure, a gaping void remains, and the awakened spiritual individuals will suddenly feel naked, weak, and lost in a world whose meaning was given by the inspiration of Presence.

The sudden departure is not, in Pasolini’s view, God’s whim, taking away what He once gave, but rather an inherent element of religious experience. The intimate experience of communion with divine force must at some point be confronted with the outside world, which lacks His Presence. That is why, in Pasolini, God is a Guest, not a father. The second part of the film is a record of this very struggle of spiritually awakened individuals with the absence of God and their desperate attempts to fill the barren void of their lives.

Mysticism Today

In the depiction of divine seduction, it is not so much the fatalistic dualism that seems controversial, but rather the portrayal of sexuality as the means by which the Guest enlightens the various characters.

This could, of course, be interpreted as an expression of the provocateur spirit of the Italian director, who never shied away from controversy or challenging common moral standards. However, in this case, I believe that eroticism is primarily a logical consequence of Pasolini’s proposed vision of spirit and body, rooted in ancient and early Christian thought. This extremely anti-dogmatic, heretical vision is not, for Pasolini, a tool to attack the Church. The director is not interested in overthrowing church dogmas in this film (after all, the erotic scenes are very restrained and modest), but rather in presenting a particular, universal vision of faith and the spiritual dimension of reality.

Pasolini draws on the sexual magic present in ancient religions, weaving it together with Christian symbolism and biblical messages of love, to create a sensualist interpretation of God that transcends human interpretations, assuming only a temporary form for the benefit of the believers who are discovering Him.

Although personified and real, the God of Theorem also has the character of a personal emanation, influencing individual experiences rather than broader historical events. He does not seem to follow a grand plan, remaining indifferent to what people will do with the spiritual liberation He has granted them. The household members are not so much actively seduced as they are, under the influence of the Guest’s magnetism, luring and provoking Him to come closer. Thus, Pasolini’s God departs from the vision of a creative, proactive force, adopting a form closer to the ancient concept of a violent, elemental power that complements the raw world of matter. The ancient motifs in the interpretation of divinity are also justified in the context of associating the arrival of God with the Greek figure of Hermes, suggesting a highly synthetic understanding of divinity by Pasolini, one that transcends specific systems and doctrines.

In this sense, it is neither surprising nor shocking to depict a God who enlightens through sexuality. He is meant to embody a metaphysics, an idea that gives meaning to existence in a materialistic world.

Pasolini’s God is neither Creator, Father, nor Shepherd—He is a mystical, undefined being, a spark that initiates life and movement in a world immersed in apathy. Such an interpretation seems to be a gesture of restoring archaic religion’s ontology of the senses and experience while rejecting the logocentric canon of contemporary systems. The God personified by the Guest is not accessible through reason but through the senses. By accumulating erotic energy, He brings illumination through sexual acts and His physical closeness, while the words and actions of His lovers are merely their own attempts to understand and process what they have experienced. His intentions are neither evil nor good; they are simply acts of liberation, a reevaluation of the characters’ previous perception of the world.

It is their mistake to trust Him as a shepherd in the Christian sense.

The emptiness left by God

In my view, the synthetic vision of religious experience enhances its totality, which is sometimes lost through the “processing” of defined theological systems. In the face of such a personal and all-encompassing Presence, the Void left by the inevitable departure of the Guest becomes all the more painful. The liberation from stagnation that He brought by seducing the inhabitants of the wealthy house comes with a price—an awareness that they are, in fact, wandering in the desert, and that His presence was only a fleeting glimpse in their intimate world, while the world remains as it was before.

This confrontation is emphasized by Pasolini’s use of the poetics of a hostile reality, pressing upon the characters. Through this, the affluent residence turns out to be a cramped cage, the developed industrial city a soulless hell, and managing the factory—a sign of economic status and prestige—becomes a burden that hinders the attainment of self-awareness.

When the Guest leaves their home, the family members begin attempts to fill the Void left by His Presence. Alone, just as they experienced His blessing alone. The son, to whom the Guest revealed his inner richness and clearly showed the meaning of life, tries to fulfill himself through art. However, increasingly violent creative acts cannot mask the barrenness of his efforts. Pietro utters one of the key sentences in Theorem: We must invent new techniques (…) make our world unlike any other. (…) No one can understand that the author means nothing, that he is abnormal, inferior, that he twists and writhes like a worm to survive. The boy, whose name can be seen as a link between this character and the director, tries to create ever-new, more radical ways to mask his fear, ultimately leaving home to become an artist painting revolutionary slogans on glass.

In this ironic way, Pasolini seems to expose the pursuit of creative expression by humans, which only serves to hide the fact of their loneliness and sense of abandonment by the inspiring force, revealing itself to be fragile and meaningless.

Lucia, the wife/mother, follows a similar but more nihilistic path after the Guest’s departure. Freed by Him from the golden cage that stifled her femininity, she tries to drown out the Void with the same thing He did—with sex. As a result, she plunges into debauchery, which only intensifies her loneliness and fear of the cold, soulless reality, also arousing in her an overwhelming sense of Catholic guilt. Her daughter, awakened as a conscious and mature individual, increasingly feels the pain of abandonment and the burden of the freedom given to her. Deprived of a foundation for herself, she flounders aimlessly around the house and garden, eventually sinking into catatonia, a return to her inner self, deeper behind the old veils.

Odetta, the most suppressed before the visit, feels the Void most acutely, losing the sense she had briefly gained. It is telling that the struggles of the daughter and wife have a romantic-erotic tone. Odetta’s pain, trying to recreate happy moments with the Guest, has undertones of longing for a lover, while Lucia, liberated from marital oppression, ultimately loses herself in sexual self-oppression. Their examples most clearly show the ambivalence of corporeality, which can simultaneously be a means of achieving harmony and breaking stagnation, as well as a tool of destruction.

After the divine impulse, each character, in their own way, realizes what a world without spiritual inspiration is. Different strategies are adopted by Emilia, who was the first to approach the Guest, and Paolo, who was His last lover. Both follow a prophetic-mystical path, clearly seeking an escape from a world dominated by materialism. The housekeeper Emilia leaves the family shortly after the Guest’s departure and returns to her native village, where she begins a silent life as a mystic. A representative of the lower social class, she processes the divine experience based on traditional, folk faith, which gives her the strength to perform miracles—healing a child afflicted with a kind of leprosy with a glance, and in one of the most memorable scenes of the film, levitating above a building.

In an act of fervor and historical mission, she eventually allows herself to be buried alive at a construction site. This act, a religious transformation of her earlier suicidal tendencies, may be an attempt to “fertilize” the spiritual future world, as well as an expression of helplessness in the face of a society that does not understand the essence of her transformation. The culmination of her storyline is the tears of happiness visible at sunset during the burial—their meaning, however, remains ambiguous, and the significance of the sacrifice undefined. Emilia’s martyrdom, though it may give hope for a better tomorrow, more likely seems to be a symbolic act of burying ancient, authentic, and primordial spirituality and faith by modern technocratic society.

Just as the head of the family was the last person to fall into the Guest’s embrace, his portrait ends the film. Paolo, who earlier accused God of cruelty and a will to destroy, sinks even further into doubts and confusion, which the Presence was supposed to alleviate. For the father, whose name perhaps not coincidentally matches that of the director, awareness is a curse, and the encounter with the Guest is a burden. Realizing that his life is, in fact, a barren desert, in a hermit-like gesture, he renounces control over the factory, which he hands over to the workers (we watched comments on this decision in the prologue) and sets off, naked—literally and spiritually—into the volcanic desert of Etna, which finally appears in its full glory. Is he trying to meet God there again? Whatever he is looking for, he does not find it, and realizing that God had indeed led him into the desert, he lets out a desperate scream. A scream that is simultaneously the scream of all divine orphans, exposed by the religious experience and confronted dispassionately with a secularized reality.

The curse of freedom

In the final act of Theorem, Pasolini’s socialist-Marxist inclinations are subtly revealed.

The sequence featuring the workers at the beginning of the film is not accidental. As they comment on their boss’s decision to hand over the factory, the workers, representatives of the working class, are lost, doubting their future. They hide their fear and sense of abandonment behind clichés about the bourgeoisie’s detachment from their problems and the impossibility of cross-class understanding. On the surface, this establishes a narrative perspective as a critique of the emptiness of the lives of the economic elite, illustrated by the story of the factory owner’s family. However, the stories of the five characters seduced by the Visitor suggest something else. After the divine impulse, each character realizes in their own way what the world is like without spiritual inspiration and struggles with the consequences of their naive trust in God’s protection.

As a result, they experience what can be described as the “curse of freedom,” losing themselves in a sense of meaninglessness brought about by their awakening and abandonment without spiritual guidance. The “orphaned” workers, condemned to self-determination, seem to show the same symptoms.

Pasolini’s metaphysical drama thus simultaneously criticizes modern society, which condemns authentic, intuitive spirituality to be buried, and distances itself from the ideas of proletarian revolution. The economic dominance of the bourgeoisie, in his eyes, seems to be just another dogma, the loss of which causes anger and fear, much like the family’s misplaced trust in God as a protector. Basing one’s identity on a system ultimately leads to painful disorientation when its foundation disappears. In this light, the titular theorem can be interpreted as a sign of the fatalism of human actions based on the functioning of a religious or social system.

The film’s critique is not aimed at any particular class but rather at the civilizational tendency to create dogmatic systems that close people off from primal spiritual forces, the confrontation with which ultimately leads to their exposure and loss. At this point, it does not matter whether the Visitor is God, Satan, or simply a charismatic cousin—he embodies all those forces that people, by trusting in various systems and ideologies, close themselves off to, simultaneously making themselves vulnerable to their sometimes disastrous influence. The film about his visit, in turn, highlights the deceptiveness of doctrines and systems. In this way, Theorem is both a metaphysical treatise on faith and a parabolic social allegory.

In the same year as the film, Pasolini—besides being a filmmaker, also a writer—published a novel with the same title. I haven’t read the book, but available information suggests it is content-wise consistent with the film. The fact that Pasolini told the same story simultaneously in both literature and film seems to indicate the significant importance he attached to the vision proposed in Theorem. In it, the Italian created a kind of intimate exposition of his understanding of spirituality and the nature of the contemporary world, demonstrating his intellectual and cinematic genius. It is also a narrative in which Pasolini perhaps most perfectly combined the most important, seemingly contradictory themes in his work: humanistic mysticism, social engagement, and provocative perversity, which intertwine into an extraordinary, mystical treatise on the essence of faith, the void of existence, and the cultural constructs that surround them. Amen.
