 The Congregation for the Doctrine of the Faith at the Holy See, which is the official authority for approving private revelations on behalf of the Catholic Church, did not declare Mother Eugenia's writings heresy, so this is not controversial to the Catholic Church.A common human source of false revelations is pareidolia, where people see visions or hear voices where there are none.The church claims that apparitions and visions cannot be photographed and messages and locutions cannot be recorded.
