What an odd response. There’s no single volume of all U.S. local, state, and federal law, along with all judicial precedent. Would you, then, attempt to convince us that “no one knows exactly and completely what is the law in the United States”? :nope:
So, no: I didn’t say that “no one knows exactly and completely what are the infallible dogmas of the Catholic Church.” I only said that there’s not one single bound volume of the texts of the official teachings, as compiled by the Church. Big difference there.
This doesn’t mean that “we can’t easily know which teachings are … infallible,” either. You’re right, of course, that we are to assent to Church teaching (infallible or not). But, “the point” would be that it would be
nice to have such a single-point-of-reference document.
Here’s the thing, though:
such a document can never exist. Let me try to convince you of this assertion (since it’s something that I’ve never seen anyone assert, but it seems to be correct): * Any such document, put together outside the magisterium, would be a fallible compilation of infallible teachings. That would render it somewhat unhelpful – if one attempted to use it, the response would be “well, that list, itself, isn’t authoritative!”
- Any list, put together at some point in time, couldn’t call itself the “complete list”… since it would only be complete up until new doctrine was named. If it were put together by an outside entity, it would always require updates. Seeing the ways that people attempt to wedge one Church teaching against another, it would seem that having various versions (in various languages) of such a document, would simply be inviting discord and debate.
- Incompleteness would be a problem for the magisterium, too – it would, by definition, always be false: after all, how could a “complete list” in the 19th century fail to include the Assumption and still call itself ‘complete’? Wouldn’t that mean that the 19th century list was not infallibly correct?

- If there was infallible teaching and an infallible list… which would be authoritative? Which would be seen as the more important: the teaching or the inclusion in the list? Wouldn’t that mean that, by definition, there would be ‘relevant’ and ‘irrelevant’ infallible teaching? That’s problematic.
So, I think that, by definition, there
cannot be any magisterially authoritative “complete list of doctrine”, ever. However, there are lots of ways to know what the magisterial teaching of the Church is, even in the absence of an ‘official list’. As I mentioned earlier, the Catechism is a great place to encounter the Church’s teaching…
