When Timothy (an Israelite of the sect of Jesus) talks about the Scriptures, he refers to the Judaic Scriptures (a collection of books or "the Bible). Timothy was writing a letter or an address to others; he was not adding to the Scriptures in question.

When we read about Jesus saying, "It is written....," he was speaking to people, was not writing, and was not referring to his word as being written in the future and adding to the Scriptures in question. It was some Christians later on that considered the Christian scriptures as a body of writings and called it the New Testament. The New Testament is not and addition to and hence not a part of the Bible. [To create confusion, some Chrstians started using the word "bible" to include the Bible and the New Testament.]

Now, to go back to the original question of this thread, the Gospels and the rest of the corpus called New Testament have been considered canonical by the Catholic Church and by others; that is, authentic (unlike other gospels and writings, which branded "apocryphal"). They are the authentic ones, truly representing the genuine speakers of the faith, and are so declared by the infallible Pope. So, the theory goes, the Pope makes official pronouncements by divine inspiration; so all the dogmas of the Chruch are sanctioned by God. Thus, the Catholic-selected writings are the authentic works which contain true accounts. Hence, the letters of Timothy, Paul and the others, The Acts, the Apocalypse, and the Gospels are truthful works. They are inspired by God in the sense that they contain only true statemnts. I don't know what cretin [French for "Christian simpleton"] ever said that the New Testament and the Old Testament are "the word of God" in the sense of "dictations by God." The dogmatic theory is that all the Scriptures are truthful or were so inspired or guided by God as to be truthful.

Those who maintain that all the Scriptures are the written word of God are obviously not thinking: Are the prayes in the Scriptures and the devotional poems (psalms) in the O.T. what God said? Was God praying to himself, begging forgiveness, etc.? All all the epics of the O.T. -- the tales of military exploits and plunderings (in some of which God intervened to assist, to stop the movement of the sun, etc.) -- tales told by God to those who wrote them down? Or are they oral lessons, composed by rabbis, to the children of Israel, which were eventually edited and written down? Were the tales of creations and the genealogies in the O.T. told by God to the prophets (the speakers or announcers to the Israelites) and eventually written down?

Only humans are the authors of what is written in all the Scriptures, but, as I indicated, there is the dogmatic theory that all that was written down is truthful -- and it is, if we do not look at the errors of fact, at the contradictions and the fallacies in the thinking which was written down. (The O.T. is a great work for ethnological research, since it reveals what ancient people thought, what they knew, and how they thought, when they taught all the lessons in question.) To note that certainly there are many tales in the O.T. which report God speaking to somebody, such as Moses, lords of the Israelites, etc. In the N.T.. God speaks through angels in dreams, but His voice was also heard when John baptised his cousin Jesus.

The Gospels are BIOGRAPHIES of Jesus the Christ. As in the O.T., there is always a speaker or narrator. In the Gospel according to Matthew, for instance, the narrator is a person called Mathhew. Mathhew was a teacher or preacher of what we read in written form. He narrates life facts about Jesus and reports sayings and preachings of Jesus'. (Matthew, not God, is the narrator, the historical reporter, but the Church tells out that the narration or report is historically true.) If a report says that Jesus performed a miracle, well, the evangelist is actually reporting what somebody else said; he was not a witness to a miracle, but if, a priori, the evangelist is truthful, that means that Jesus really performed a miracle. If the O.T. is truthful, then the Elohim really created the world as if by magic; Yahveh really fashioned the world (including Adam out of clay and by breathing into that product); Yaveh really stopped the sun's movement for a while; and so forth.
Everything written is true, whether consistent or contradictory, and whether verisimilitudinal or not. That's God's word!

The verse from 2 Timothy really only refers to the Hebrew Bible. There was no NT Canon yet and the author would not have thought he was writing "scripture" himself.

Even it made an unambiguous claim that the NT in its entirety was being referenced, it still doesn't say that all Scrioture is the word of God and...more importantly...it would be a completely circular argument anyway. It would be nonsensical to try to argue that the Bible is the word of God because the Bible says so.
