Who determined it was divinely-inspired?

God knew it was when He wrote it and said so within it.

I mean, the individual books. There were a lot of "Gospels" and epistles being circulated in the early years of Christianity. How did Christians determine what was divinely-inspired and what wasn't?

Who determined [or recognized] it was divinely-inspired?

Interesting circular logic you use. Sounds very similar to what the Mohammedans say about the Koran.

“But for the authority of the Catholic Church, I would not believe the Gospel.”- St. Augustine 354-430 AD

Catholics, like St. Augustine believe the Gospel to be God's own infallible word because the only authority established on earth by Our Lord Jesus Christ, (which was before the Gospel was in written form), the Church, declares it to be so.

It is silly to say the Catholic Church does not believe the bible. It's a Catholic book.
