That's not how the Church defines inspiration.
In Christian terms, inspiration involves everything God wanted the writer to say, but also does not prevent the writer from including concepts that are dictated by the confines of human nature and the limitations of culture and the period in which the author lived.
For instance, the authors of the New Testament tend to write of seizures as demonic possession. Was it really demonic forces causing the humans to suffer or were these seizures that Jesus was curing?--Compare Mark 9:20-27.
The only reason epileptic episodes are called "seizures" is because ancient cultures believed spirits were seizing control of people and causing them to act this way. The description of epileptic episodes in the gospel Scriptures matches in vocabulary the way they are described in other first century literature.
Most agree that Jesus was curing seizures, not actually performing exorcisms in these particular cases that are described like this. This type of limited composition does not invalidate the value of the inspired work in the eyes of Christianity, nevertheless. No actual demons were involved, but that was due merely to the way people spoke of seizures back then. The cures, teaches the Church, were still authentic, it claims, even if the descriptions are faulty based on first century limitations.
This goes for the Final Discourse on Mount Olivet. It was a discourse perhaps about judgment upon Israel but due to anti-Jewish sentiments in the Church, became colored as something else.
You may think it garbage, but the Church does not. It can see past the human limitations to the truths of Jesus to see warnings about never thinking that what you have with God is permanent just because it's a temple or some deep understanding. It can all come tumbling down and change in a minute, and because you are not ready, your world can end and you with it!
I'm a Jew, not even a Christian, but I know they (Christians) don't need things to be as exact and literal as you to keep their faith in it. They have yet to call it garbage, yet believe exactly as I wrote. Who do you think I got all that I've posted on this thread from? Not me! It's from the footnotes of the official Catholic Bible of the UK, the Jerusalem Bible, and the USA, the NABRE, and the ecumenical, academic standard NRSV. None of this was my opinion or invention.
These are words of believing Christians, not mine. I am Jewish.
