With respect, there is no possible way you could say that if you've read both articles.
Mattei ( and Vennari and the rest) disagree with Van Noort, yes (which means they disagree with pretty much all the other theologians, too). But they have done nothing else. Which is typical of someone talking about something they know nothing about.
Vain, ad infinitum assertions to the contrary are not arguments. The idea that canonizations aren't infallible by declaration has far reaching implications. You are reducing infallibility to something which is ensured naturally, not supernaturally. You are also making it something which has no practical value, since we have no idea just what exactly about the process makes it infallible, which shrouds every definition in doubt. If you could at least give a definitive answer on what precisely about the process, your position would at least have a semblance of respect. But you, Mattei, et al. haven't even done that. How do you expect to be taken seriously?
