Peace be with you!
Actually, the Canon of Scripture was declared at the council of Rome in 382 and again at the 3rd and 4th Councils of Carthage in 397 and 419. You can check the canons of those councils if you like.
I don’t get why Protestants always–and I do mean ALWAYS–claim that the Church “added” the Deuterocanonicals to the Bible at Trent. I don’t know who first came up with that claim, but it is completely false. What Trent did was not to create a canon of Scripture; what Trent did was to RE-AFFIRM the SAME canon of Scripture in the face of NEW OPPOSITION from Protestants. Trent simply said “These books have always been part of Scripture and the issue is not open to debate”. That’s what happened at Trent.
I think that the Bible was intended for people to read (afterall, Paul does say that all Scripture is beneficial to read), but not to INTERPRET privately. That is what the Church is for. One has only to look at the, what, 35,000 Protestant denominations to see that clearly that is NOT what Christ intended. But I guess sola scriptura is the way to go…
In Christ,
