New Advent disagrees with you. Your lack of theological distinctions sinks your arguments.
No, Pax, his understanding is the correct one. You have it wrong. I cited the part of CE which clearly states that an Ecuмenical Council must be considered infallible due to the protection of the Holy Ghost promised to the Church ... even beyond the strict scope of papal infallibility. You R&R constantly ignore this and believe that the Magistiirum can become thoroughly corrupt and harmful to souls. While allowance can be made for good faith due to the confusion of the times, this particular articulation of R&R is in fact unquestionably objectively heretical. You need to stop droning on about the limits of strict infallibility and realize what you're saying, that the Magisterium and Universal Discipline of the Church can defect.
