Notice Where Canon Discussions Begin

What assumptions are being made at the start of the discussion? For example, when somebody like Cameron Bertuzzi is assuming the truthfulness of Christianity, that certain individuals of past generations were Christians, what writings attributed to those individuals are genuine, etc., did he get to those conclusions by a means he's criticizing Protestants for utilizing? Cameron has made a series of canonical judgments, about canons other than the canon of scripture, before he begins his criticisms of Protestantism on canonical matters. How does he know which documents attributed to Athanasius or Augustine, for instance, are genuine and which aren't? What's the canon of Athanasius' writings or Augustine's, Jerome's, Innocent I's, and so forth? Cameron probably frequently relies on Protestant scholarship on patristic issues, much as he relies on other sources who aren't conservative Catholics on patristic issues and issues pertaining to the Bible, church history, and so on. That includes scholars who are highly antagonistic toward Christianity, like Bart Ehrman, a source Cameron recently cited on canonical issues. Ehrman not only has been a scholar in the field of New Testament textual criticism, but also has done work in related areas. His doctoral thesis was on textual issues in Didymus the Blind, a church father. So, Cameron's conclusions on matters related to the Bible, church history, the church fathers, church councils, etc. depend on fallible, probabilistic judgments derived largely from scholarship that isn't part of conservative Catholicism (moderate Catholics, liberal Catholics, Protestants, Eastern Orthodox, atheists, agnostics, etc.).

When conservative Protestants are faulted for depending on sources they have significant disagreements with, keep in mind that conservative Catholics do the same. When conservative Protestants are faulted for relying on fallible, probabilistic judgments about controversial and complicated issues, keep in mind that conservative Catholics do the same. Etc.
