Who has written the holy book, Bible?

The Bible is a compilation of several individual books. These books were written by different human authors at different periods of time under the inspiration of the Holy Spirit. These were later compiled into a single book, “The Bible” under the authority of the Holy Catholic Church.

Dei verbum, the Second Vatican Council’s Dogmatic Constitution on Divine Revelation states the following in paragraph 11.

“Those divinely revealed realities which are contained and presented in Sacred Scripture have been committed to writing under the inspiration of the Holy Spirit. For holy mother Church, relying on the belief of the Apostles (see John 20:31; 2 Tim. 3:16; 2 Peter 1:19-20, 3:15-16), holds that the books of both the Old and New Testaments in their entirety, with all their parts, are sacred and canonical because written under the inspiration of the Holy Spirit, they have God as their author and have been handed on as such to the Church herself. In composing the sacred books, God chose men and while employed by Him they made use of their powers and abilities, so that with Him acting in them and through them, they, as true authors, consigned to writing everything and only those things which He wanted.”
