Last year, a horror film was released. It was about the "real" case of Maria Rossi, who murdered three persons as a result of a failed exorcism. Is it true? The film itself was advertised as that the Holy See condemns it. I know that at some times, exorcism needs repeating. Also, did the priest do the exorcism properly? Like, at exorcism one must not use the Blessed Sacrament.
