The document originates from the long experience of the last century, which saw cases where the local bishop (or bishops of a region) rapidly declared a phenomenon’s supernatural nature, only for the Holy Office to express a different decision later.
From Vatican News:
A new document from the Dicastery for the Doctrine of the Faith published on Friday, May 17, has updated the norms for discerning alleged supernatural phenomena. The norms come into force on Sunday, May 19, the feast of Pentecost.
The document is preceded by a detailed presentation by Cardinal Víctor Manuel Fernández, Prefect of the Dicastery, followed by an introduction and six possible conclusions. The procedure allows for faster decisions while respecting popular devotion.
As a rule, the Church’s authority will no longer be engaged to officially define the supernatural nature of a phenomenon, a process that can require large amounts time to thoroughly study an event.
Another new norm involves the explicit involvement of the Dicastery for the Doctrine of the Faith, which must approve the local bishop’s final decision and which has the authority to intervene motu proprio at any time.
Many cases in recent decades have involved the former Holy Office, even when individual bishops have expressed themselves. However, the interventions have usually remained behind the scenes and were never made public.
The Dicastery’s new explicit involvement also relates to the difficulty in circumscribing phenomena, which in some cases reach national and even global dimensions, “meaning that a decision made in one Diocese has consequences also elsewhere.”
The document originates from the long experience of the last century, which saw cases where the local bishop (or bishops of a region) rapidly declared a phenomenon’s supernatural nature, only for the Holy Office to express a different decision later. Other cases involved a bishop saying one thing and his successor deciding the opposite (regarding the same phenomenon).
Each event also required lengthy discernment periods to evaluate all elements in order to reach a decision on the supernatural nature or non-supernatural nature of the phenomena. These time periods sometimes contrasted with the urgency to give pastoral responses for the good of the faithful.
The Dicastery began revising the norms in 2019, leading to the current text approved by Pope Francis on May 4.
CNA sums it up:
The Vatican’s top doctrinal office is centralizing its authority over the investigation of alleged Marian apparitions and other religious phenomena under new norms it issued Friday, a break from past protocols that gave local bishops greater autonomy in discerning such cases.
While emphasizing that “discernment in this area remains the task of the Diocesan Bishop,” the new guidelines state that the Vatican’s Dicastery for the Doctrine of the Faith “must always be consulted and give final approval to what the Bishop decides before he announces a determination on an event of alleged supernatural origin.”
