In the Catholic Church, the Devil's Advocate, formally known as the Promoter of the Faith, plays a crucial role in the canonization process. This role, abolished in 1983 but its function retained, ensures rigorous scrutiny during the Church investigation. The Devil's Advocate's purpose at a recognized stage of the process is to meticulously examine all evidence of holiness presented for a potential saint. They rigorously challenge the validity and sufficiency of the presented material, searching for flaws or contradictions. This adversarial approach aims to guarantee a thorough and objective assessment before a declaration by the Pope of sainthood. Their objective is not to oppose holiness but to ensure the integrity of the process.
