Canonization

Canonization is the formal process by which a Christian church or communion declares a deceased person to have entered heavenly glory and authorizes public veneration of that individual as a saint, typically adding their name to the official list, or canon, of recognized saints. It is the definitive act that elevates a person to the full honors of the altar, often following a preliminary declaration of beatification. While most developed in the Roman Catholic Church, analogous procedures exist in Eastern Orthodoxy, Oriental Orthodoxy, and, in modified forms, some other Christian traditions. The word derives from the Greek κανών (kanón, “rule” or “measuring rod”), indicating that the person’s life measures up to the standard of heroic virtue and that their name is inscribed in the canonical catalogue of saints.

History of Canonization

In the earliest Christian centuries, veneration of holy persons arose spontaneously out of popular devotion, particularly directed toward martyrs. Local bishops would approve and regulate the cult, often by authorizing a feast day and the enshrinement of relics. The first known example of a formal papal canonization occurred in 993, when Pope John XV canonized Bishop Ulrich of Augsburg at a synod in Rome, thereby transforming what had been a local cult into a universal one. Over the following centuries, papal authority over the recognition of saints slowly increased, partly to curb unregulated local cults and the multiplication of spurious relics.

The medieval process became increasingly juridical. Popes Alexander III (12th century) and Innocent III reserved the right of canonization to the Holy See, a principle later codified by Gregory IX in 1234. With the establishment of the Sacred Congregation of Rites by Pope Sixtus V in 1588, the investigation of candidates’ lives, virtues, and miracles was centralized. Urban VIII’s decrees (1625–1634) further tightened the norms, prohibiting public veneration of a person not yet beatified or canonized and establishing the distinction between beatification (which allowed local or limited cult) and canonization (which mandated universal cult). The modern era saw periodic adjustments, notably the radical reforms introduced by Pope John Paul II in the apostolic constitution Divinus Perfectionis Magister (1983), which simplified procedures, reduced the historic role of the “Promoter of the Faith” (colloquially the “devil’s advocate”), and emphasized historical-critical method. Subsequent popes, especially Benedict XVI and Francis, have refined the process, including strengthening the scrutiny of miracles and the use of collegial consultation.

Process in the Catholic Church

The Catholic Church understands canonization as an infallible papal declaration, confirming that the saint is in heaven and may be publicly invoked and venerated throughout the universal church. The process, conducted under the supervision of the Dicastery for the Causes of Saints (formerly the Congregation for the Causes of Saints), proceeds through several stages.

Preliminary Phase and Declaration of Heroic Virtues

A cause normally begins no less than five years after the candidate’s death (the pope may dispense from this waiting period). The local bishop, after receiving a petition from the faithful and ascertaining a genuine fama sanctitatis (reputation for holiness), initiates a diocesan inquiry. A postulator is appointed to gather documentation: writings of the candidate, witness testimony, and any evidence of miracles. The collected material is sent to the Dicastery for the Causes of Saints, where a positio (a comprehensive biography and theological evaluation of virtues or martyrdom) is compiled. If the candidate is judged to have lived the theological virtues (faith, hope, charity) and the cardinal virtues to a heroic degree, or to have died as a true martyr for the faith, the pope issues a decree declaring the person “Venerable.” No public cult is yet permitted.

Beatification

For a non‑martyr, a miracle attributed to the intercession of the Venerable must be proved. The alleged miracle—almost always a healing—is rigorously investigated by medical and theological experts. If approved, the pope presides over the beatification rite, after which the person is called “Blessed.” A blessed may be venerated locally (within a diocese, religious order, or region) and assigned a feast day. For a martyr, no miracle is required for beatification, only proof of martyrdom.

Canonization

A second miracle, occurring after beatification, is normally necessary for canonization. The scrutiny follows the same medical–theological process. Once the miracle is accepted, the pope convokes a consistory of cardinals and bishops, and later celebrates the canonization Mass, during which he formally inscribes the name of the Blessed in the catalogue of saints. From that moment, veneration extends to the universal church. Although the requirement of two miracles is standard, the pope can dispense from it, as occurred with the canonization of Pope John XXIII (2014) for whom Pope Francis dispensed the customary second miracle.

Recent Modifications

The 1983 reform replaced the lengthy adversarial proceedings with a single diocesan phase and a Roman phase, both focused on historical and scientific accuracy. The literary and historical qualifications of the experts were emphasized. More recently, in 2017, Pope Francis issued the motu proprio Maiorem hac dilectionem, which opened a new pathway for beatification: the offering of one’s life—a heroic act of charity by a person who has voluntarily and knowingly accepted premature death for the sake of others, even if not strictly a martyr. Additionally, the requirement for a second miracle can be waived, as noted, and Pope Francis has encouraged causes that reflect the “everyday holiness” of laypeople and families.

Eastern Orthodox and Oriental Orthodox Traditions

In Eastern Orthodoxy, the term “canonization” is occasionally used, but the more traditional expression is “glorification.” The process is less juridical and more liturgical and synodal. There is no centralized Vatican-like dicastery; each autocephalous or autonomous church, through its holy synod, may recognize a saint. Glorification usually follows a long period of spontaneous popular veneration, which includes reports of miracles, incorrupt relics, and a widespread fama sanctitatis. A synodal committee gathers evidence, and the synod then issues a formal proclamation (a tomos) and a service in the saint’s honour, effectively “listing” the saint in the church’s calendar. There is no equivalent of beatification as a distinct preliminary status; the proclamation implies full sainthood and universal veneration within that particular church. In modern practice, Orthodoxy has glorified many new martyrs of Ottoman and communist oppression. The Oriental Orthodox churches (Coptic, Armenian, Syriac, Ethiopian, etc.) follow similar synodal practices, rooted in their own canonical traditions, where the local holy synod acts after establishing enduring popular devotion.

Other Christian Denominations

The Anglican Communion does not have a formal canonization mechanism that claims to “make” a saint in the Roman Catholic sense. Instead, some provinces, such as the Church of England, maintain calendars with commemorations of “heroes of the faith,” figures whose lives are held up as examples of Christian witness but without implying a definitive judgment on their heavenly state. A few Anglo-Catholic circles use the term “canonization” loosely for these insertions, but no universal juridical act exists. The Lutheran and Methodist churches generally reject the notion of canonization as a mediatorial function of the church, though they may honor exemplary Christians day in their liturgical calendars without any process of declaration.

Other Uses of the Term

Outside theology, “canonization” describes the process by which an author, text, or work of art becomes accepted into the recognized body of classic literature, music, or intellectual tradition—the “canon.” Scholars in literary criticism and cultural studies analyze how social, institutional, and political forces shape the elevation of certain works to canonical status, often drawing an analogy with the religious process of recognizing saints. While sharing the root idea of inclusion in an authoritative list, this secular usage lacks the elements of miracle verification and heavenly intercession.
