Common mistakes
Don't say
Claiming Constantine or the Council of Nicaea decided the New Testament canon.
Instead
Note that no canon list survives from Nicaea and that core books were already broadly recognized a century earlier; canon councils came later (Hippo, Carthage) and ratified existing consensus.
Don't say
Treating any patristic citation of a non-canonical book as proof it was once considered Scripture.
Instead
Distinguish between a text being read, quoted approvingly, or valued for edification and a text being treated as authoritative Scripture on par with recognized books; ancient authors cited many texts without granting them canonical status.
Don't say
Assuming full uniformity across all ancient Christian communities as if disagreement never existed.
Instead
Acknowledge the genuine disputed periphery honestly while showing it is a bounded, explicable set of cases rather than evidence of total canonical chaos.
What would change my mind? — Christian position
Discovery of solid patristic evidence that the core Gospels or Pauline corpus were genuinely contested as a whole (not merely individual disputed books) well into the fourth century would significantly weaken confidence in early, broad recognition.
What would change my mind? — Skeptical position
Clear documentary evidence of a formal, non-consensus-based imperial or conciliar decree simply imposing a previously unrecognized list of books, absent prior wide usage, would support the 'imposed canon' narrative.
Why does this matter?
The canon question underlies every other claim about biblical authority, since one must first know what counts as Scripture before asking whether it is inspired, inerrant, or historically reliable. It also bears directly on interfaith and interdenominational dialogue, since Catholic, Orthodox, and Protestant Bibles differ at the margins. Understanding the actual historical process, rather than popular myths about Constantine, is essential for having an informed rather than caricatured conversation about biblical authority.
