Well........interesting. This video will make no impact for two reasons.
1) It is about 12 minutes to long. It sounds like aprofessor trying to fill time with a grand point in a classroom, but the point is a letdown.
2) He almost makes it seem as though you cannot have a rational discussion about the bible if you don't understand translation. I don't think the JW's showed up at the door suggesting that subject. In fact, I doubt that is the way the phone call began earlier. because it is his area of expertise, he drives it that direction when they share a scripture, and then says they don't know the point they are making.
Now he may be right in the sense that parroting "facts" is never a good thing, and it is better to have actually researched. However, i am sure most Christians in general, have little concept if any as to how the bible came into existance, how it is translated, what the flash point for translation are, and even less about exegesis and early manuscripts. So his premise comes out flawed, even though the meat of his point is 100% accurate. JW's do not follow truth AT ALL COSTS.
So honestly, I don't think much of this guys video. Comes off as kind of self aggrandizing as well in just my humble observation.
