of use of "the 'names' derived from the alleged private revelation attributed to Mrs Gabriele Bitterlich" may have been one of the reasons for enacting the Congregation's more detailed 1992 rules against the use in the movement's "ministry and apostolate" of "the theories originating from the alleged revelations of Mrs Gabriele Bitterlich concerning the world of the angels and their personal names, groupings and functions", and its ruling, "Exorcisms may be carried out only in line with the Church's norms and discipline on the matter, and with the use of formulas approved by the Church." In 1993, the Brazilian priest Frederico Cunha was found guilty in Madeira of the murder of a 15-year-old who resisted his homosexual advances and was imprisoned. He maintained his innocence both then and later. In April 1998 he absconded to Brazil, from where he, as a Brazilian, could not be extradited to Portugal, but could have been subjected to a new trial, if the Portuguese government had requested it. The prison term to which he was condemned expired on 8 April 2018. According to Portuguese and Austrian media, Cunha was a Canon Regular of the Holy Cross. By his own account and that of the Diocese of Funchal, he was incardinated in that diocese.
