It highlights a series of talks that Rev. Paul Smith is having, and gives a synopsis, but even the synopsis is interesting. Makes a good point, the talks give the details.
While the story is fiction, Smith says it reveals four important truths, and “attacking the bad facts in the story is like accusing Jesus of making up the story of the Prodigal Son and therefore saying there is no truth to it.”Those 4 truths are original diversity, lost gospels, marginalizing women, and distorting the humanity of Jesus.
The article gives a little info on each of those 4. And if you go to Rev. Paul Smith's website, under teachings, you can download 3 of the 4 talks. (The last one will be up in about a week.) The series is called, "Why the Da Vinci Code is TRUE!: (and today’s Christianity is dysfunctional)".
I've read the first one, and found it quite interesting and informative. I look forward to reading the others.
