It is against the continued belief of many aspects germane to Christian belief. It's an attempt to rid Christianity of these erroneous beliefs and create a new understanding of the Bible by correcting its errors. It is against, "anti," the current comprehension of the Bible. Not saying this is bad, but in as much as very few Christians appear to have any desire to correct their beliefs, I very much doubt they will regard this news as something "they have to know to treat the New Testament as the foundation of the religion."
Where I think it comes into play is as I said to reach to those in the middle who are not the dyed in the wool hardline traditionalists, who have always never really taken the stories of the Bible as literal facts but nonetheless consider themselves Christian. In other words, they don't
really believe Jesus walked on water, but take those as symbolic stories about an elevated figure of their religion's traditions, still cherishing them as representing higher truths. When those people see and hear these hardline fundis quoting the Bible to support their particular flavor of worldview, they lack any real knowledge to counter these other "Christians" with, since it appears the fundis are more knowledgeable about the Bible than they are. You give them some knowledge, it takes power away from the fundis.
Granted, the article has flaws in what it's saying as Well Named pointed out above, but it gets the dialog going in the middle, whereas previously it's just Pat Robertson versus Richard Dawkins, neither of which on the extreme ends speaks to the more centrist views of the American middle, where religion isn't a matter of being literally true, or literally false. If the article isn't about destroying faith (Dawkins), but educating people about their own faith while honoring it as a tradition, it is in my opinion a better conversation to be had than letting the extremes have all the voice. You'll never convince the extremes with reason, but you will help the middle have a clearer understanding.
