So how do you know the "Catholic Church " has given you an infallible new testament list? Martin believe the bible was corrupted in the old testament and new testament letters .. like hebrews, james and Revelation. ..
Because, aside from the Roman Catholic Church, the other ancient apostolic churches, those being the Eastern Orthodox (Russians, Greeks, Antiochians, Romanians, Bulgarians, Georgians, Serbians, et cetera), the Oriental Orthodox (Armenians, Syriacs, Copts, Ethiopians, Indians), and the Assyrian Church of the East all agree on the canonicity of the 27 book Athanasian canon.
Some of the books Martin Luther sought to exclude are not used liturgically by all of these churches (the EOs don't read Revelations, the Syriacs and Assyrians use liturgically only a subset of books). However, they all recognize the validity of the 27 book Athanasian canon.
This canon was first enumerated by Athanasius (my avatar is an icon of him); Athanasius was vital in defending the doctrine of the Trinity against Arius and the Arians. So no Trinitarian Christian frankly has any valid reason to object to the canon, something most Lutheran theologians have accepted (Martin Luther's idea of "antilegomenna" was never very popular, even among Lutherans).
So how do you know you have an infallible new testament list since the list itself is extra biblical extra apostolic. ..?
Well, this is a valid argument against sola scriptura or nuda scriptura, in that the NT lacks a table of contents; the canon is a fourth century development. That said, there are good reasons for doubting the antiquity and apostolic authenticity of the various writings rejected by the canon, for example, the Gnostic apocrypha.
