A Catholic Scholar’s Long View of Scientology

A 2005 study by Aldo Natale Terrin argued that Scientology should be examined as a religion in its own right. Read today, alongside his death in 2024 and his later 2017 book on the subject, the text appears less like an isolated intervention than part of a long scholarly engagement.

Nearly two decades before his death, Italian Catholic priest and scholar Aldo Natale Terrin posed a question that still carries weight in debates about religion and modernity: can Scientology be understood as a religion for a modern society? In a 2005 report written in Padua, Terrin answered that question in the affirmative, arguing that Scientology should be evaluated not through slogans or social suspicion, but through the same conceptual seriousness scholars bring to other religious traditions.

That matters because Terrin was not writing as a casual observer. He worked within a Catholic academic world linked to the Istituto di Liturgia Pastorale in Padua, an institute officially incorporated into the Faculty of Theology of the Pontifical Athenaeum Sant’Anselmo in Rome. His report was not a Vatican declaration, nor did it claim to speak for the Catholic Church as a whole. It was, rather, the judgment of a priest-scholar trained in philosophy, theology and the history of religions, applying his own method to a movement that has long been contested in public discourse.

The rediscovery of that text becomes even more significant now that Terrin’s own life has come into fuller view. The Diocese of Padua announced that he died on 9 January 2024 at the age of 82, after a long career devoted to teaching and research. Seen in that light, the 2005 study reads not simply as an old document resurfacing online, but as part of the intellectual legacy of a Catholic scholar who spent decades reflecting on ritual, spirituality and the religious imagination.

Not a passing remark, but a sustained inquiry

One of the strongest features of Terrin’s report is that it does not present itself as a first impression. At the outset, he explains that he had already written about Scientology in the 1980s, including in his book Nuove religioni. Alla ricerca della terra promessa and in an essay on Scientology’s search for liberation from human limits. In other words, by 2005 he was returning to a subject he had already studied, not improvising a judgment from afar.

That continuity would become even clearer later. In 2017, Terrin published the full-length volume Scientology. Libertà e immortalità, issued by Morcelliana. The existence of that later book changes how the 2005 report should be read. It was not a one-off defense or a brief academic curiosity. It was an early stage in a longer scholarly project that Terrin continued to develop over the years.

How Terrin defined religion

The report’s central question is not whether Scientology is popular, understood, touches vested insterests or how much it is socially accepted. It is whether Scientology fits a serious definition of religion. Terrin rejects both a purely bureaucratic definition and a purely reductionist one. He argues that religion cannot be explained away as a mere social label, an ideological construction or a legal convenience. At the same time, he does not reduce religion to one narrowly Christian template.

Instead, he proposes what might be called a combined definition. On one side stands the phenomenology of religion: a real encounter with the sacred, understood as something that exceeds ordinary empirical reality. On the other side stand social and ethical conditions that matter in the modern world: human dignity, freedom, reason, democracy, the rule of law and a distinction between politics and religion. For Terrin, both sides matter. A religion must point beyond the merely material, but it must also exist in a way that can be understood within a modern pluralist society.

He gives particular importance to two ideas: the sacred and salvation. In his view, no religion can be understood without them. A tradition must refer to something greater than the measurable world, and it must offer some path of liberation, redemption or ultimate fulfillment. Those paths may differ widely from one religion to another, but Terrin argues that without this horizon of salvation, one cannot really speak of religion in the fullest sense.

Why he believed Scientology met that test

Once he establishes that framework, Terrin turns to Scientology’s own language. The decisive concept for him is the Thetan, which he reads as the movement’s central affirmation of the spiritual nature of the person. In his interpretation, the Thetan is not a decorative idea or a metaphorical flourish. It is the sign that Scientology places spirit, not matter, at the center of human identity.

From there, he moves to salvation. Terrin argues that Scientology presents a path in which the human being seeks increasing freedom from the limits of MEST — matter, energy, space and time — and moves toward greater self-determination, spiritual awareness and, finally, the horizon of the infinite. That structure, he says, places Scientology within a recognizable religious logic. It may not resemble Christian soteriology in every respect, but it still offers a narrative of spiritual ascent, liberation and relation to the divine.

This is one reason Terrin repeatedly describes Scientology in relation to gnostic forms of religiosity. He does not use the word as an insult or a sensational label. He uses it descriptively, to say that Scientology understands salvation largely through knowledge, awakening and the recovery of the spiritual self. In that respect, he sees parallels not only with ancient esoteric currents, but also with broader patterns found in Eastern religious traditions, where liberation is closely connected to insight and spiritual discipline.

He also notes that Scientology’s concept of the Supreme Being is less dogmatically fixed than in some Western traditions. Yet he does not regard that as disqualifying. What matters to him is that Scientology points beyond the finite and situates the spiritual journey in relation to transcendence. For Terrin, that is enough to place it within the field of religion, even if its theological vocabulary differs from that of Catholicism (otherwise it would be Catholicism and not Scientology).

The issue of “science” and spiritual method

Terrin’s report also addresses one of the most disputed aspects of Scientology: its technical language and its use of the word “science.” Rather than reading that vocabulary in the narrow modern sense of laboratory science, he argues that Hubbard’s usage should be understood in an older sense closer to ordered knowledge or wisdom. In that reading, Scientology is not trying to replace religion with chemistry or physics. It is presenting a disciplined method for spiritual clarification (or clearing as scientologists name it).

This point is important because it shows Terrin trying to interpret Scientology from within its own conceptual grammar. He does not dismiss its practices simply because they sound unfamiliar or technical. Instead, he argues that Hubbard’s emphasis on method, sequence and intelligibility belongs to a broader effort to structure spiritual liberation in rational form. Whether or not all readers find that persuasive, it is a serious attempt to understand rather than caricature.

That seriousness extends to Terrin’s broader warning against easy labels. He is clear that scholars should not erase criticism, but they should begin with the internal logic of belief. For him, the first task is to understand what a religion says it is doing before deciding whether it succeeds, fails or deserves critique. That approach is one reason the report still feels relevant today, when debates about minority religions are often driven more by cultural reflex than by careful analysis.

Why the report still matters now

Terrin’s study does not settle every argument about Scientology, and it does not remove the missunderstandigns that are controversies that surround the movement in different countries. But it does something more durable. It shows that a Catholic scholar, writing from within an established academic and ecclesial environment, concluded that Scientology could not simply be pushed outside the category of religion without serious intellectual loss.

That judgment carries added force because it now stands alongside the arc of Terrin’s own life: his earlier writings on new religious movements, his 2005 report, his 2017 book, and his death in 2024. Together, they reveal consistency. He did not glance at Scientology and move on. He returned to it over time, refining an argument that the movement should be examined as a genuine religious phenomenon and not only as an object of polemic.

For readers today, that may be the most important lesson of all. In an era when public debate often rewards instant labeling, Terrin’s work argues for something slower and harder: describing a religious movement in terms that take its own beliefs seriously, even where disagreement remains. Whether one ultimately shares his conclusions or not, his work reminds us that pluralism begins not with approval, but with the discipline of understanding.
