I really don't see how you get this from the text. Really.
You quoted:Inspiration can be considered in God, who produces it; in man, who is its object; and in the text, which is its term.
God, to be precise, is not "inspired". He inspires, and He inspires the mind of man, as the article's quote of 2 Pet 1:21 suggests.
In a section called
Erroneous views proposed by Catholic authors
the article condemns the view that the Church can make a "merely human writing" inspired. Earlier is says that no writing of the post apostolic age can be in the canon.
Can you help me see how the article says what you say it says?
Did I misread the text? Are you confirming that only scripture is the inspired word of God and error free?
