"Now, since I think I can safely assume you believe it is the Catholic church's decision to make, then the canonicity of those books was only decided by the Catholics after the Protestants had excluded them, at the Council of Trent. Before then, it was left as a matter of individual conscience, which means your accusation against Luther is basically an ex post facto indictment."

You misunderstand the workings of the Church. The Church does not make proclamations in anticipation of error or conflict, it makes them in response to conflicts or challenges. It operates much like a baseball umpire, rendering a call only after a play. GK Chesterton once described the Church as being like a cart careening down a mountain road at breakneck speed, only correcting its course when bouncing off a wall or rail. Trent only reaffirmed the Canon that had been established in 381 AD in response to the Reformation.

“Trent only reaffirmed the Canon that had been established in 381 AD in response to the Reformation.”

You’re speaking of the First council of Constantinople? What canon, in respect to books of the Bible, did they establish? I’m going to need a link on this claim, because your Catholic Encyclopedia doesn’t even try to claim such a thing. The Vulgate hadn’t even begun to be translated yet at that time!
