Canonization

← Encyclopedia

Canonization is the formal act by which a church declares that a deceased person is a saint: worthy of public veneration, and held to be already in the presence of God. The word reaches back to the canon — the authorized list, the rule — and that is what the act originally did. It entered a name onto the roll of those the church would honor by name in its liturgy.

For most of the first Christian millennium there was no procedure at all. The martyrs and confessors revered as saints became so by the recognition of the communities who had known them; a local bishop assented, the cult grew, and the saint’s day entered the calendar of a town or a region. Canonization in this period was an act of memory more than of law. The shift came gradually in the Western church between the tenth and thirteenth centuries, as the papacy drew the power to make saints toward itself. By a decree of Pope Gregory IX in the 1230s the judgment was reserved, in principle, to Rome alone — a centralization historians read as part of the wider medieval consolidation of papal authority.

What grew up around that reservation was a juridical process, refined over later centuries into something resembling a trial. A cause is opened and argued by a postulator; evidence of the candidate’s life, writings, and reputed holiness is examined; and, in the procedure as it long stood, miracles attributed to the person’s intercession had to be demonstrated to the church’s satisfaction. The office once charged with pressing every doubt and objection, the promotor fidei, became known in popular speech as the devil’s advocate. In Roman Catholic practice the path runs by stages — the title Venerable, then beatification, then canonization — each marking a further degree of recognized sanctity and a wider permission to venerate.

The Eastern Orthodox churches arrive at much the same end by a different road. They speak of glorification rather than canonization, and tend to understand it less as a verdict that confers sainthood than as the church’s formal acknowledgment of a holiness God has already shown — the recognition of a saint rather than the making of one. The distinction is fine but real, and the two traditions guard it.

Behind the legal machinery lies a claim the procedure can document but not produce. What the church says it is doing, when it canonizes, is recognizing a fact about the unseen world: that this particular person stands among the blessed and may be asked to pray for the living. The investigation tests the evidence available on earth; the thing affirmed is held to lie beyond it. That gap — between a process that can be conducted and a state that can only be believed — is the heart of what canonization is, and the reason the church has always treated the act with such care.
