Therefore not only must it be said that the Pope is infallible in matters of faith and morals, when he defines doctrines about faith and morals, but that this infallibility is that infallibility which the Church enjoys.
Therefore, someone who would simply assert that the Roman Pontiff is infallible when he defines something about faith or morals has by no means comprehended the meaning of our definition. Nor is the meaning of our formula comprehended by someone who simply asserts that the Roman Pontiff is infallible when he defines something which simply must be held by the Church. The two things must always be joined so that the meaning of our formula be correct and true. Moreover, this formula seems most suitable to express both things: “The Roman Pontiff, when he defines a doctrine of faith and morals to be held by the universal Church, enjoys that infallibility with which the divine Redeemer wished His Church to be endowed in defining doctrine of faith or morals.”
Therefore, in this entire definition, the following three things are contained:
- The Roman Pontiff, through the divine assistance promised to him, is infallible, when, by his supreme authority, he defines a doctrine which must be held by the Universal Church, or, as very many theologians say, when he definitively and conclusively proposes his judgment;
- the object of these infallible definitions is doctrine about faith or morals;
- in respect to the object of infallibility, generically proposed in this way, the infallibility of the Pope is neither more nor less extensive than is the infallibility of the Church in her definitions of doctrine of faith and morals.
Therefore just as everyone admits that to deny the infallibility of the Church in defining dogmas of faith is heretical, so the force of this decree of the Vatican Council makes it no less heretical to deny the infallibility of the supreme Pontiff, considered in itself, when he defines dogmas of faith.
However, in respect to those things about which it is theologically certain - but not as, yet certain “de fide” - that the Church is infallible, these things are also not defined by this decree of the sacred Council as having to be believed “de fide” in respect to papal infallibility. With the theological certitude which is had that these other objects, apart from dogmas of the faith, fall within the extension of the infallibility which the Church enjoys in her definitions, so, with that same theological certitude, must it be held, now and in the future, that the infallibility of definitions issued by the Roman Pontiff extends to these same objects.
Now, as to what concerns the method for treating this, matter in our voting, most eminent and reverend fathers, you can see for yourselves that everything in our formula is so interconnected that those things which are found in the following suggested corrections - touching upon the object of papal infallibility and on the relation which exists between papal infallibility and the infallibility of the Church – are not able to be joined to our formula, nor can anything be separated from our formula. Therefore there remains nothing to do except first submit to a vote of the most reverend fathers this formula of the Deputation. But if this formula is accepted - as, with the help of God, I hope it will be – then no further votes need be sought in respect to the following suggestions, to the extent that they concern the object of papal infallibility and the relation between papal infallibility and the infallibility of the Church. This is so because, as I have just said, the matter found in these suggestions cannot be taken into our formula while saving its meaning, nor is anything able to be omitted from our formula without ruining its tight connections. Therefore a vote will first be sought in respect to our formula, and, in case it is accepted by the general congregation, another further relatio about those suggestions concerning the object of infallibility and the relation between papal infallibility and the infallibility of the Church will no longer be necessary.
Therefore I think I can refrain from any further observations about these suggestions and only say something if a particular thing seems to be worthy of note.
