The process towards Sainthood starts locally after a Catholic, who is considered to be holy, dies. The person's writings & life are investigated by the local bishop, either for heroic virtuousness or/and martyrdom. If the local bishop is satisfied, it goes on for further evaluation to the Vatican, by a panel of theologians. Then they look for evidence of at miracle.
To prove a person worthy of sainthood, the Catholic Church conducts a detailed investigation into their life and virtues after their death, starting with a local bishop. The process involves examining heroic virtues or martyrdom, verifying miracles attributed to the individual, and culminates in the pope's declaration. This structured approach ensures that only those truly deserving are canonized as saints.
