The Vatican's Dicastery for the Doctrine of the Faith recently revealed more details about its 1974 ruling on reported apparitions in Amsterdam tied to the devotion of the "Lady of All Nations." The bishops said the visions which Ida Peerdeman described between 1945 and 1959 were not supernatural and that there was no need for further investigation by the doctrinal office. This decision, which was followed by a unanimous 'no' vote by the cardinals during their meeting in March 1974, was ratified by Pope Paul VI in April of the same year.

While the Vatican had generally kept such decisions to itself in the past, it now announced this "so that the holy people of God and its pastors may draw the appropriate conclusions." An initial finding of no evidence of supernatural phenomena by Bishop Johannes Huibers of Haarlem in 1956 was first confirmed by the Holy Office, and then again by the Congregation for the Doctrine of the Faith in 1972 and 1974.

On the "Lady of All Nations" title, the Vatican says it is theologically acceptable, but cautions that such acceptance does not imply any endorsement of the supposed supernatural phenomena that surround its origin. Bishop Johannes Hendriks of Haarlem-Amsterdam reiterated in 2021 that a private veneration in devotion toward Mary under this title is commendable, but must not be confused with the disputed messages and apparitions attributed to Ida Peerdeman.
