Fr Eric Mascall interestingly pointed out that the article 'POPE' in Addis's and Arnold's Catholic Dictionary did at one point in its history ... mutate. Here is a passage from the edition of 1905:
It must not be supposed for a moment that the Pope is an absolute monarch. He cannot ... annul the constitution of the Church ordained by Christ. His power of definition is limited by a multitude of previous definitions due to his predecessors, to the councils, to the ordinary exercise of the Church's magisterium through the pastors united to the Holy See. If the Pope obstinately rejected an article of faith which had already been proposed by the Church, and to which the Pope owes allegiance as much as the simplest of the faithful, he might be judged and replaced. 'It has always been maintained', says F. Ryder ... 'that for heresy the Church may judge the Pope, because, as most maintain, by heresy he ceases to be pope'. Bellarmine and Turrecremata maintain that he would cease to be Pope ipso facto; Cajetan and John of St Thomas require formal deposition.
The last three sentences, which I have rendered into italic type, were omitted by the 1951 edition.
Apparently, this passage gave no offence, seemed in no way problematic, in the quarter-century after Vatican I had, under the presidency of B Pio Nono, defined the Primacy of the Roman Pontiff and his Infallibility. It is interesting to note that it had become too dangerous ... or tactless? ... to reprint it in the pontificate of Pius XII.
It is sometimes felt that the 'problem' of the Papacy has something to do with the Decrees of Vatican I. I have never believed this to be so. It was in the middle of the twentieth century, under Pius XII, that inflated views of the Papacy reached a dangerous pitch. And, as Joseph Ratzinger pointed out, it was in the years after the Council that the erroneous view spread that "a pope could do anything". And now, under Papa Bergoglio, the disease has become even more acute.
