To supplement my post on the unity of the Bible, I created an infographic that lists each book of the Bible and its author (or possible author in some cases). Each entry contains the name of the author, name of the book, the date of composition, and some details on the author. For the dates of the books, I mainly consulted Andrew E. Hill and John H. Walton, A Survey of the Old Testament, 3rd ed. (Grand Rapids: Zondervan, 2009); D. Edmond Hiebert, An Introduction to the New Testament: Three Volume Collection (Waynesboro: Gabriel Publishing, 2003); and my class notes from my Bible survey classes from seminary. However, any mistakes are entirely my own.
The purpose of this graphic is to add to the argument I made in my post on the unity of the Bible. The names and dates I provided are the traditional (and more conservative) authors and dates of the 66 books of the Bible. The graphic shows that there are around 40 authors of the Bible, and the books of the Bible were written over a period of about 1,500 years. It would seem that a group of people from vastly different backgrounds (including fishermen, shepherds, physicians, kings, prophets, tax collectors, etc.), locations, and times would produce a jumble of literature that would not cohere whatsoever. Yet, in the Bible we find a comprehensive view of reality and the human condition and a complete and coherent story of creation, fall, and redemption.
Blessings and enjoy!
