How does anyone become saint in the Catholic Church? See 6 Vatican Rules

3) Diocesan phase (local). Testimonials, documents and writings are collected. The historical committee raises everything. Theological censors evaluate the texts. A diocesan court formalizes acts and ends the inquiry under seal.

4) Roman phase (in the Vatican). The dicker receives the material. A rapporteur guides the writing of Positio – the dossier that demonstrates life, virtues or martyrdom and the fame of holiness. Theologians and, if applicable, historians make an opinion. Cardinals and bishops of the Dicsteria vote. With approval, the Pope may sign a decree of heroic or martyrdom virtues. The title becomes venerable.

5) Beatification. It is the intermediate step. For martyrs, no miracle is required. For the others, it takes a miracle attributed to the intercession of the venerable. Cure must be complete and without scientific explanation. Medical Commission, Theological Consultants and the Session of Cardinals and Bishops analyze the case. With the papal decree, the venerable is proclaimed Blessed.

6) Canonization. To turn saint, the rule asks for a second miracle, which occurred after beatification. With positive opinions and the Pope’s decree, the Church recognizes universal worship.

Special cases. The Pope can dispense with deadlines or miracles in exceptional situations. “There are exceptions. John XXIII, for example, was canonized without the demand for a second miracle. John Paul II had its process accelerated, with the waiver of five years after death” (Vatican News).
