I used to have a copy of the KIT. As I remember, the back of the book is filled with a good number of rather shaky justifications for the oddball NT translations seen only in the NWT. (Stake vs. cross, no immortal soul, no eternal punishment, no bodily resurrection of Christ, the tetragrammon in the NT, an impersonal Holy Spirit, and, of course, Jesus as a second and lesser God.)
Are WT doctrines THAT wacky? A few (actually A LOT) on here regard the 607BC, Blood and shunning as a bit dodgy but some of the above in the quote can be proven using either the bible or a good Greek-English lexicon.
