From Jonathan Moorhead.
I wish I knew. There is no possible way, in my opinion, to know the answer to this question. How can we measure the influence (both good and bad) of certain works upon Christians throughout the centuries? If we were talking about the most influential books of the 21st century in the U. S., The Purpose Driven Life would top the list. But I think we want to focus upon books that have had a good influence upon Christians, right?
Of course, at the top of the list is the Bible. But as for five other books?
Here is a list that I think would have to be contenders for the spot, in no particular order.
1. The Pilgrim’s Progress by John Bunyan. (Who, besides Michael Haykin, hasn’t read it?)
2. The City of God by Saint Augustine. (Christianity defended and shown to be superior to the religion of the world)
3. The Apology by Tertullian. (The most important work of the ‘Father of Latin Christianity’)
4. Matthew Henry’s Commentaries. (Pastors across the world have these on their shelves.)
5. Against Heresies by Irenaus. (Whenever you see some ‘new’ doctrine, look here to see if it has already been refuted.)
If you don’t like my list, make your own.
