Ubi Arcano Dei Consilio §69

⁶⁹ We, therefore, who are now the heirs and depositories of the ideals and sacred duties of Our Venerated Predecessors, and like them alone invested with competent authority in such a weighty matter and responsible to no one but God for Our decisions, We protest, as they have protested before Us, against such a condition of affairs in defense of the rights and of the dignity of the Apostolic See, not because We are moved by any vain earthly ambition of which We should be ashamed, but out of a sense of Our duty to the dictates of conscience itself, mindful always of the fact that We too must one day die and of the awful account which We must render to the Divine Judge of the ministry which He has confided to Our care.
