so for example with "Just War" we see this passage:
> it is important to reaffirm that the “just war” theory, which has all too often been used to justify any kind of war, is now outdated.
This would clearly be thought to be an error from a Catholic viewpoint, because the right to wage "justified war" comes from the individual right to self-defense, as applied to a collective group of people legitimately defending against aggression (maybe lots of people here for example would argue Ukraine is legitimately justified in waging defensive war against Russia, for example).
Hence while it is good to promote peaceful resolutions of conflict, the document goes too far in condemning legitimate self-defense.
(So while the whole long document likely says correct things about AI and the dignity of work, it also adds in things like the above that Catholics would clearly reject. Typically Catholics would accept what a pope is writing so if you're getting someone who claims to be pope teaching erroneously, this points to a bigger problem for Catholics.)
