In short: The Church did, guided by the Tradition handed down from the apostles. That’s how the list, the canon, got settled. CCC 120

The answer, in writing

Church teaching

The Catechism says it was by the apostolic Tradition that the Church discerned which writings belong in the list of sacred books. CCC 120

That complete list is called the canon: 46 books of the Old Testament and 27 of the New. CCC 120 CCC 138

Our words

No one voted on it in a single meeting. The Church recognized, over centuries of reading them at worship, which books carried the apostles’ faith, and later councils confirmed the list.

Next step: Can we trust the Gospels?

Honestly? The best answers come from people, not websites. Take the next step: find a parish near you
