[daniel1212]

And yet even if the likes of Cardinal Cajetan and the Catholic Encyclopedia etc were wrong and Florence did infallibly define the canon so that disagreement should have ceased as it did with Trent, what does that avail the papists?

For since its judgments were manifestly wrong about what the NT church believed, then why should its judgments on the canon of Scripture (which writings are of God) necessarily be believed?

They no more warrant belief than all the judgments of who was of God by those who sat in the seat of Moses did., despite their own pedigree and being the magisterial stewards of express Divine revelation.

[Petrosius]

And yet even if the likes of Cardinal Cajetan and the Catholic Encyclopedia etc were wrong and Florence did infallibly define the canon…

You keep ignoring my point. It was not that Florence dogmatically defined the canon, but rather that there was a general consensus since the 4th century, and that such would be a part of the Ordinary Magisterium. This, by its very nature, does not issue dogmatic declaration.
