A few years back I mentioned the Rev 5v10 blatant mis-translation to an active JW, he said he would consult his greek friend, who also knew N.T greek, and get back to me on that one.
Funny, he never got back to me. LOL
It is evident that many translators, and I am not sure we can glorify the WT with that title, I personally think they never really translated, they simply cobbled together their own version, but it is evident that actual translators are influenced by their own Theology/Christology to come up with the renderings that they do.
The WT have over the years argued in favour of their dodgy renderings in a reasonably able manner in many cases, even John 1v1, but have argued unsuccessfully, and often disingenuoosly in a good number of cases.
The Revised NWT is even worse, and now less honest, than the original, for example, they put brackets around some of their blatant interpolations in the original, they no longer do so, giving the impression that they have some Manuscript suppport for what they have printed, which is simply not true.
