The Church of the Word Incarnate, Charles Journet: He (Cajetan) explains first that the power to elect the Pope resides in his predecessors eminently, regularly and principally. Eminently, as the "forms" of lower beings are in the angels, who, however, are incapable in themselves of exercising the activities of bodies (Apologia, cap. xiii, no. 736). Regularly, that is to say as an ordinary right, unlike the Church in her widowhood, unable to determine a new mode of election save "in casu", unless forced by sheer necessity. Principally, unlike the widowed Church, in whom this power resides only secondarily (no. 737). During a vacancy of the Apostolic See, neither the Church nor the Council can contravene the provisions already laid down to determine the valid mode of election (De Comparata, cap. xiii, no. 202). However, in case of permission (for example if the Pope has provided nothing against it), or in case of ambiguity (for example, if it is unknown who the true Cardinals are or who the true Pope is, as was the case at the time of the Great Schism), the power "of applying the Papacy to such and such a person" devolves on the universal Church, the Church of God (ibid., no. 204).
