📖 How Does the Church Make a Saint? Canonization Explained

It is easy to treat this as church bureaucracy, interesting trivia with no real weight on your own walk with God.

⚠️ But strip away the paperwork and one real question is sitting underneath all of it. How does anyone actually know whether a life was worth imitating. Not admired from a distance. Imitated.

Scripture answers that question before any Vatican office ever existed.

"Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us,"

Every Christian, Catholic or Protestant, is told to run a race while watching lives that already finished theirs well. Canonization is the Catholic Church's own careful, documented attempt to answer who belongs on that list, and to show its work doing it.

Whether or not you accept the process, the instinct behind it, that a finished life can still teach you something about how to run your own, is one every believer already owns.

Catholic Straight Answers lays out where every cause actually begins. After someone dies with a local reputation for holiness, what the Church calls fame of sanctity, a cause can open once the normal five year waiting period has passed.

The local bishop, not a Vatican office, starts things moving. He appoints a tribunal, gathers testimony from people who actually knew the person, examines their writings for soundness of doctrine, and records any favors reported through their intercession.

📌 A sealed, authenticated copy of all of it then goes to Rome. At that point the person is formally called a Servant of God, the first real title in the process.

The Roman office receiving that file has changed names more than once. Vatican News traces it to the Sacred Congregation of Rites, set up by Pope Sixtus V in 1588, which Paul VI split in 1969 into one body for worship and a separate Congregation for the Causes of Saints. John Paul II renamed it again in 1988, and Pope Francis' 2022 constitution gave it its current name, the Dicastery for the Causes of Saints.

Once the Dicastery accepts a cause, a postulator, appointed to argue for the candidate, pulls everything into one document. Catholic Straight Answers describes it as part biography, part legal brief, part scholarly argument, known as the positio.

A Vatican official called the promoter of the faith, popularly nicknamed the devil's advocate, raises formal objections against the file. The 1907 Catholic Encyclopedia, hosted on New Advent, describes a process built entirely around answering his questions, called dubia, before any stage can move forward. In that era there was, by its account, only one promoter of the faith and one assistant handling every single cause in the whole Church.

A panel of nine theologians then votes on whether the evidence shows heroic virtue, or in a martyr's case, death specifically for the faith. Catholic Straight Answers reports that six positive votes send the cause to the Dicastery's own bishops and cardinals, and a two thirds vote there sends it on to the Pope himself.

If he agrees, he signs a decree and the person becomes Venerable. Nothing about that title is a guess or a feeling. It is a formal judgment that a specific life produced the fruit Jesus said to look for.

"Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?"

Venerable is not yet permission to publicly venerate anyone. Catholic Straight Answers is specific about what closes that gap. One verified miracle, attributed to the candidate's intercession after death, is required for beatification, unless the candidate is a martyr, who can be beatified on the martyrdom alone.

Even then, beatification is limited. The newly titled Blessed can be venerated publicly, but Catholic Straight Answers notes that permission usually only covers one diocese, country, or religious order, not the whole Church at once.

💡 Why a miracle at all. EWTN quotes Monsignor Michele Di Ruberto, once an undersecretary at the Dicastery, putting the Church's own logic plainly. People can be wrong about who was holy. A miracle, by definition, comes only from God, who does not deceive. In that framework a verified miracle functions as God's own confirmation of a human judgment that could otherwise be mistaken.

That logic is not new. Peter leaned on the same connection between miracles and divine approval the very first time he preached after Pentecost.

"Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:"

A reported miracle does not go to theologians first. Aleteia traces organized medical review of these claims back to 1743, when the future Pope Benedict XIV, already an expert on canonization law, created the first standing register of physicians for the job.

The board in its current form dates to 10 July 1959, when Pope John XXIII merged two earlier bodies into a single Medical Board, often called the Consulta Medica. Two experts carry out a first review of the case. A seven member commission from that board then studies it in full.

📌 Nothing moves forward on a simple majority. Aleteia reports that revised 2016 rules require the commission's conclusions to be approved by a qualified majority, at least five of seven doctors, or four of six when a smaller panel sits, and that a single case cannot be sent back for review more than three times. Only once that panel finds no natural explanation does the file move on to the theologians who weigh its spiritual meaning.

Canonization asks for the same proof again. Catholic Straight Answers states that a second miracle, attributed to the candidate's intercession after beatification, is normally required before a Blessed can become a Saint. That one plus one standard is itself a modern simplification. The 1907 Catholic Encyclopedia describes a far heavier older requirement, up to four miracles for beatification alone depending on how the evidence was gathered, before John Paul II's 1983 reform cut it down to the standard used today.

The Pope reviews the finished file personally and makes the declaration in public, usually at a Mass in Saint Peter's Square, the same square where Pope Francis canonized Mother Teresa on 4 September 2016, the final word on a cause that had opened almost two decades earlier.

Once that happens, the person's feast day enters the Church's own calendar for every parish, not just the one diocese beatification allowed. That is the same calendar behind the difference between a solemnity, a feast, and a memorial, and the reason All Saints Day exists at all, as one shared day for every canonized name the ordinary calendar has no room for individually.

📌 One more claim needs stating carefully, not flattened into a fact. The 1907 Catholic Encyclopedia, citing Aquinas, says most theologians across history have held that the Pope cannot err when he canonizes. The same entry is just as clear that this has never been formally defined as a required article of faith, only treated as theologically certain, and that a minority of serious theologians have disputed it. Say it the way that source does. Widely held, not universally settled.

That five year wait mentioned at the very start is not absolute. Catholic Straight Answers confirms it is the normal rule before a cause can even open, set as part of John Paul II's 1983 reform. It is also entirely within the Pope's own discretion to set aside.

Mother Teresa is the clearest example. EWTN News, carried through Catholic News Agency, reported in 2005 that John Paul II himself had waived the wait for her, letting her cause open only two years after her 1997 death instead of five. She was beatified in October 2003 on the strength of a healing credited to her in 2002, and VOA News reported that the Vatican approved a second miracle, the inexplicable cure of a Brazilian man's brain tumors, in December 2015, clearing the way for canonization.

John Paul II received the same courtesy in reverse. That same 2005 report records Pope Benedict XVI announcing, within weeks of John Paul II's own death, that he would waive the five year wait for him as well. UPI reported that Pope Francis canonized John Paul II on 27 April 2014, and the Associated Press reported that roughly 120,000 people filled Saint Peter's Square when Francis canonized Mother Teresa there on 4 September 2016.

⚠️ Notice what a waiver does and does not do. It moves the paperwork faster. It never skips the tribunal, the theologians, the medical board, or the two miracles. Every shortcut in this process has still run through the whole process.

Most Protestant traditions have no version of this process at all, and it is worth hearing the actual biblical case rather than dismissing the whole thing as a difference in style.

GotQuestions makes the core argument directly. It reads the New Testament as using the word saint for every believer, living or dead, not for a smaller class the Church certifies later. Paul opens an entire letter addressing a whole ordinary congregation that way.

"Paul, an apostle of Jesus Christ by the will of God, to the saints which are at Ephesus, and to the faithful in Christ Jesus:"

From there, GotQuestions argues that Scripture gives every believer direct access to God and never instructs anyone to route a prayer through someone already in heaven, which leaves the Protestant case against the whole practice resting on something simpler than a disagreement over paperwork.

📌 Say the actual disagreement plainly, because it is not about the history above. Catholic teaching does not claim canonization manufactures holiness. It claims to recognize a holiness the Church believes already exists in heaven. Most Protestant readers reject the premise underneath that claim, that a believer in heaven can hear and relay a prayer at all, which is the same disagreement running underneath the wider split between Catholic and Protestant church calendars. It is worth adding that the earliest saints, figures like Andrew the apostle, were never run through this tribunal at all. Their recognition came from centuries of ordinary veneration, long before Rome built a formal process for anyone else.

You do not have to resolve every doctrinal question here to let this topic shape you honestly. Seven ways to do that.

None of these verses mention a tribunal or a medical board. They are the raw material underneath the question canonization is actually trying to answer: who finished well, and how would anyone know.

Strip away the headlines and three things remain true.

📌 Canonization is a documented process, not an announcement. A bishop's tribunal, a positio, nine theologians, a medical board, and two verified miracles all stand between a death and a declared saint.

📌 The waivers only ever move the calendar. Every shortcut Rome has granted, to Mother Teresa, to John Paul II, still ran through the same tribunal and the same miracle standard everyone else faces.

📌 The real disagreement with Protestants is not about the steps. It is about whether a believer already in heaven can hear and carry a prayer at all. Settle that question and the rest of this process becomes a detail, not the argument.

Wherever you land on that question, Hebrews 12:1 still asks something of you directly. A finished life, examined honestly, is there to change how you run the part of the race still ahead of you.
