Pope jurisdiction over bishops & Vat I: The actions of Pius VII in Tam Multa and Qui Christi domini thus cannot be used to sustain the thesis that the pope has the right to remove diocesan bishops at will. The sequel to this episode is extremely important for our question. Abp. Deschamps of Malines presented a postulatum to the First Vatican Council in 1870 in connection with the ‘Petite Église’. He requested a formal condemnation of this movement as schismatic. He proposed an amendment to the Council’s chapter on the Roman primacy that would assert the pope’s power to suppress dioceses, and supported this amendment by reference to Pius VII’s actions in 1801.[17] (See E. Mangenot, ‘Anticoncordataires’, DTC 1/1, col. 1377). The Council Fathers refused to accept this amendment.[18] This claim about papal power therefore cannot be described as having been taught by the First Vatican Council. The Council chose not to include this claim in its description of papal primacy when asked to do so.
