How does someone become a saint? The canonization process

A person becomes a saint by receiving God’s grace, persevering in faith and charity, and entering heaven. Canonization is the Church’s formal recognition that a particular person is in heaven and may be honored publicly.

Before a cause begins. A canonization cause ordinarily begins at least five years after the person’s death, although the pope can waive this waiting period. The person should have a genuine and lasting reputation for holiness or martyrdom. The local bishop consults the Holy See and gathers testimony, writings, and historical evidence. Once the cause is formally opened, the candidate is commonly called a Servant of God.

The main stages. The process normally follows these steps:

1. Servant of God. A diocesan investigation examines the person’s life, virtues, writings, and reputation for holiness. The evidence is sent to the Dicastery for the Causes of Saints in Rome.
2. Venerable. If the pope recognizes that the person practiced Christian virtue to a heroic degree, the person may be declared Venerable. For a martyr, the Church instead examines whether death was accepted because of hatred for the faith.
3. Blessed. Beatification ordinarily requires one verified miracle obtained through the candidate’s intercession. A martyr normally does not need this miracle. Beatification permits limited public veneration, often within a particular country, diocese, or religious community.
4. Saint. Canonization ordinarily requires another miracle occurring after beatification. The pope then solemnly declares the person a saint and extends public veneration to the universal Church.

How miracles are examined. A claimed healing must be medically documented, lasting, and without an adequate natural explanation. Independent medical experts examine it before theologians consider whether it followed prayer specifically seeking the candidate’s intercession. This careful process does not treat every unusual recovery as a miracle.

What canonization means. The Church does not claim that canonized saints were sinless. Mary alone was preserved from all stain of original sin by a singular grace (CCC 490-493). Canonized saints needed Christ’s mercy, sometimes underwent deep conversion, and became examples of what grace can accomplish. By canonizing them, the Church proposes their lives as trustworthy models and recognizes their intercession (CCC 828, 956).

The details of the process are ecclesiastical discipline and can change. The call to holiness does not change: every Christian is called to become a saint (CCC 2013). Begin with ordinary fidelity today, through prayer, the sacraments, charity, repentance, and the duties God has placed before you.
