wolves are less viscous
Oh my! If wolves are less viscous, I think that makes them much more terrifying than hyenas. I don't like the idea of fluid(ish) animals sneaking up on me.
No, we assume that every word in any Bible anyone can read is false because it is complete bollocks..."
The NT (Gospels in particular) can be seen as a reasonable historical account. There would be no reason for the authors (Mathew, Mark, Luke, and John) to reword things like what Jesus said. Can we reasonably assume that to the best of their memory, that is what he said? Yes we can. Especially since we take other authors words on far less controversial topics that were written hundreds of years afterwards instead of just 30. http://www.reasonablefaith.org/establishing-the-gospels-reliability
