Yep, it ain’t the words, it’s who gets to interpret them. You say “logically”. I say, where does the Bible say that there is or should be a canon and who gets to say what’s in it and what isn’t?
It’s logical to assume that God has always had the capacity to arrange that any number of ways . . .
And I Cor 14 indicates that a local congregation of believers are sufficient to help discern what is of God and what isn’t.
And . . . over 300+ years . . . believers did.
It seems to me, most knew well before that.
It was nice to have a kind of formal declaration made.
However, congregations knew well before that, at least what the essential very kosher books to include were.
