I'm not sure you should, at least, not 100%. See the September 8, 1957 Awake! Magazine article entitled 50,000 Errors In The Bible? at:
1st page: http://www.jamaat.net/bible/AwakeArticle(1957).html
2nd page: http://www.jamaat.net/bible/AwakeArticle(1957)b.html
Can anyone verify that this is an authentic article? If so, it is quite damaging and could be very helpful when discussing any topic with a JW since they assume the Bible is not in error.
This article evokes questions in me such as:
Can the WTS produce the entire list of errors and if so, can I get a copy? If not, why not? They are claiming errors have been resolved by modern scholars so they must know what errors were fixed in order to be able to make this claim in the first place.
Can they produce the list of resolved errors and if so, can I get a copy of this one as well? If not, why not?
My expectation is that no JW has ever seen this article. And... I expect, they would NOT be able to produce the lists.
Heaven
