While there are many human authors who wrote the books of the Bible, the Catholic Church believes that God inspired these authors to write what He wanted to communicate to humanity. This means that God guided the human authors in their choice of words, their ideas, and their overall message.
The Bible is considered to be the Word of God, revealed through the words of human authors. This is why the Catholic Church refers to the Bible as inspired Scripture.
It's important to note that while God is the primary author, the human authors still contributed their own individual styles and perspectives.
