Having certitude does not preclude debate. Certitude ,or as your previous post mentioned reasonable certitude, or even absolute certitude all have different meanings . Thus to make a statement regarding certitude one must first provide a precise definition of said term. You did not define a precise definition at the outset.
Since the Canon remained the same from Cathage/Hippo until today, save for Luther,how valid and forceful was this debate.
Trent merely rubber stamped what had been done 1100 years before.
Believe what you want, end of discussion . God bless and Good night.
Now you are reasonably dealing with a valid point, and i am sorry if you assumed i was speaking about anything less than absolute certitude. Trent did affirm the historical canon of Rome which precluded the possibility of change thus enabling absolute certitude for Catholics, versus a certitude which allows doubt and change due to a matter not being definitely settled. I did state in my response to MadDawg (before you first posted) who raised this issue, “the certitude aspect is based upon the certitude which requires assent of faith, which you need an infallible definition to do” but perhaps you did not see that or it was unclear.
Grace and peace through faith in Him who is faithful and true, and His sure word of prophecy.
