That's OK, I agree with this on its face. I know we disagree on whether there is additional truth that is revealed through men as we move through time, but that's a different matter.
The Holy Spirit allows the Truth to be known, utilizing man’s attempts to write down what God has made known.
I think the Catechism reads stronger than that, but nevertheless, if you'll agree that God's "true truth" is fully revealed in the scriptures, to the extent God desired, then I think we are in agreement. IOW, God fully accomplished His mission to reveal to us in scripture everything He wanted to reveal, without error, and that the Bible is both Holy and God's word.
I see this as a matter of extreme difference with the Orthodox. Or, perhaps only Kosta. :)
The Orthodox Church holds scriputres to be true but not in the literal sense, and certainly not wihtout possible human omissioins and errors. The Church teaches that the message of the scriptures is preserved pristine, however.
Kosta defers to the Church, and its collective wisdom and knowledge, but Kosta doesn't always agree. :)

The key phrase here is - to the extent God desired - which is neither a claim that everything has been revealed nor that further revelation is disallowed.
Jesus left us His Church - with the authority to carry on His work of bringing the Good News of Salvation to the entire world.
