Hey, dan, ....
How many ex cathedra statements have you found out to have ever been made?
Is there any official church record of them? Like an ex cathedra on the ex cathedra's?
Note that ex cathedra statements only refer to papal ones, but which does not constitute all the teachings considered to be "infallible, incapable of erring. And which is necessary to ascertain in order to yield the required assent of faith. Rome has presumed to infallibly declare she is and will be perpetually infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
As to your ?,
Different Roman Catholic apologists have asserted very divergent numbers of ex cathedra papal statements. The doctrine of the Immaculate Conception and the doctrine of the Bodily Assumption of Mary were taught infallibly by Popes Pius IX and Pope Pius XII in 1854 and 1950, respectively. Hahn has proposed a two-statement canon of ex cathedra papal statements. But apologist Tim Staples says there are at least four, and likely very many more...
As evidence that the dilemma is not limited merely to a few teachings, the Roman Catholic is invited to consider the much longer list compiled by Roman Catholic priest Leslie Rumble in his book, That Catholic Church. In this book he provides his opinion that there have been 18 ex cathedra papal statements throughout Roman Catholic history. Not only does Rumble's list contain considerably more statements than Hahn's or Staples', it also contains two caveats indicating that the degree of certainty of the reliability of this (or any) list is in doubted. - http://www.examiningbeliefs.com/apol75.htm
Bishop Vincent Gasser, spokesman for the deputation “de fide” (the committee of Conciliar Fathers charged with drafting the solemn definition), delivered a four-hour speech explaining and defending the draft which was submitted to the assembled Fathers for their vote. Gasser is quoted no less than four times in the official footnotes to “Lumen Gentium” 25, which treats of infallibility…
In replying to some Fathers who urged that the procedures or form to be used by the pope in arriving at an infallible decision (i.e., his grave moral duty to pray for guidance, diligently consult the existing teaching of the Church, etc.) be included in the definition, Gasser replied: But, most eminent and reverend fathers, this proposal simply cannot be accepted because we are not dealing with something new here. "Already thousands and thousands of dogmatic judgments have gone forth from the apostolic See;" where is the law which prescribed the form to be observed in such judgments?
In other words, Gasser was able to assert "in passing"--that is, as something which did not need arguing and would be taken for granted by his audience-- that there had already been "thousands and thousands" of infallible definitions issued by the Roman see! - http://www.orthodoxanswers.org/papalinfallibility.pdf (EO source)
