"Aktuelles" (in German). Bistum. St. Gallen. 30 September 2015. Retrieved 16 August 2017. The diocese presents an archive of its press releases. The press release of the diocese is "Sensationsmeldung?" ('Sensational News?') dated 30 September 2015 and at the bottom of that is a link to Fürer's statement "Erklärungen von em. Bischof Ivo Fürer" ("Explanations by Bishop emeritus Ivo Fürer").
Some sources also name Cardinal Basil Hume as a member, but this is probably based on Marco Tosatti's misreading of Danneels's biography; see "Francesco: elezione preparata da anni". La Stampa. 24 September 2015. Retrieved 24 July 2017. The meeting of Fürer, Danneels, Hume and the French theologian Hervé Legrand in Saint Gallen that the biography mentions (M&S 217) took place in 1984, over a decade before the first meeting of the Saint Gallen Group.
