If you are a believer, then you should seriously consider reading a book by Biblical scholar, Bart Erhman. His latest publication “Forged” is a great introduction to the reasons why scholars are persuaded that a significant number of works in the New Testament are not by their purported authors. He also explains why some of the ideas we embrace today do not actually come from the bible at all, but were instead added in later.
As an example, we have a truly crazy idea that many accept as reality. Its the bizarre concept that there is one God that has three different forms, Father, Son and Spirit. We are all familiar with this concept today, it is part of our cultural baggage. However, what really surprised me is that this idea does not exist anywhere in the bible at all … except for one reference in 1 John 5:7-8.
