Lambertini’s Theological-Forensic Synthesis

Prospero Lambertini, later Benedict XIV, stands at a decisive junction in the tradition. He inherits scholastic metaphysics but writes as a jurist, canonist, theologian, and experienced Promoter of the Faith concerned with actual causes of beatification and canonization.

The 1738 Latin volume reveals a project more ambitious than a handbook of miraculous cures. Lambertini constructs what may be called a theological-forensic science of miraculous signs: he defines relevant orders of causality, distinguishes divine from created agency, asks what a miracle can signify, establishes ecclesial rules of attribution, and only afterward applies those principles to medicine, extraordinary physical phenomena, apparitions, demonic phenomena, and imagination.

Book IV, Part I of De Servorum Dei Beatificatione et Beatorum Canonizatione was published at Bologna in 1738 under Prospero Lambertini’s name before his election as Benedict XIV. Lambertini explains that he had served for twenty years as Promoter of the Faith in causes of beatification and canonization and had submitted his observations to the Congregation of Rites; he also served as a consultor. A contemporary ecclesiastical approbation describes the principal subject of the fourth book as miracles, their degrees, causes, ends, proofs, variety, differences, investigation, and truth, adding that the subject requires physical, moral, medical, and theological knowledge.

The description captures the multidisciplinary character that makes Lambertini especially valuable for a systematic theology of miracle.

The index confirms 33 chapters in Part I: Chapters I–XXXII and a final chapter on imagination. Chapters I–VII establish the conceptual and canonical architecture; VIII–XIX apply it principally to healing; XX–XXXII broaden the investigation to childbirth, resuscitation, preservative or “negative” miracles, multiplication and transformation, the elements, celestial phenomena, extraordinary bodily signs, fasting, spiritual miracles, exorcism, incorruptibility, phenomena associated with corpses, and apparitions; the final chapter examines imagination and its causal powers.

The material can be grouped more precisely as follows:

That progression matters. Lambertini does not begin with cases and call the unexplained ones miracles. He begins by constructing a doctrine of miracle capable of identifying what kind of phenomenon the inquiry is seeking.

Lambertini adds a distinct contribution to a deeply informed Catholic account of miracle:

The preceding architecture approaches miracle through ontology, epistemology, phenomenology, semiotics, providence, presence, sacramentality, ecclesiology, and comparative religion.

Lambertini adds a distinct field:

forensic epistemology.

The Church is not merely asking philosophically whether miracles are possible. It has to adjudicate an actual historical proposition:

Did event E happen as alleged, and what can legitimately be inferred from it?

That requires witnesses, medical testimony, causal exclusion, temporal sequence, physical circumstances, durability, documentary reliability, absence of fraud, theological coherence, and attribution.

Thus Catholic miracle theology contains something analogous to a court of evidence.

Lambertini's famous seven medical conditions in Chapter VIII make sense only inside this wider forensic architecture. Even they are not sufficient by themselves. A medically inexplicable cure still needs contextual and theological interpretation before the Church can call it divine.

This yields a refined formulation of the position:

A Catholic miracle is not identified merely by anomaly, inexplicability, religious context, or temporal proximity to prayer. It is identified through a convergent judgment concerning the event, the limits of created causality, its circumstances, its theological provenance, and its intelligible relation to the truth or sanctity it is alleged to attest.

That is Lambertini’s great contribution.

The 1738 Book IV, Part I contains thirty-three chapters. Its sequence is itself an argument: definition and degrees of miracle, efficient causality, rival or deceptive agencies, final causality and true versus false signs, canonical necessity and quality, medical cures, extraordinary physical phenomena, exorcistic and postmortem phenomena, apparitions, and finally imagination.

Lambertini’s distinctive achievement is therefore procedural. He turns a theology of miracle into a disciplined inquiry into fact, cause, excess, purpose, attribution, testimony, and ecclesial judgment.
