Jude 1:3: "Dear friends, although I was very eager to write to you about the salvation we share, I felt I had to write and urge you to contend for the faith that was once for all entrusted to the saints."
I guess only the Canonized had the faith entrusted to them.
Come on.
By your logic -the Catholic Church should canonize ALL? It would also follow that if ALL are saints equally it does not matter to be in error as you imply -why continue irrelevant debate amongst fellow saints?
Anyway, the Catholic Church does not teach that all saints are known or can be known by man...
I think you may just be turning scripture on its head by selective reference to fit your notions... The totality of scripture and tradition must be taken into account OTHERWISE one can come up with erroneous interpretations and end up teaching false doctrine e.g. we are all saints...
