That is an example of the wrong reasoning drilled into us by the GB/WTS.
Flash, this is a much-needed insight that points out much of the flagrant irony displayed here at the forum.
Many EX-JWs here and elsewhere have a bad taste left in their mouth after awakening from their comatose state in the Borg. Many will then react with revulsion against the hypocrisy and ignorance that the WBTS fed them, and they often do so with their scriptural training availing them in many counterarguments raised against the Borg and even against the Bible itself (many don't make the necessary distinction between the two). That is to say, in reacting against the fundamentalism and selective literalism of the WBTS, which is the foundation of all that EX-JWs loathe, many EX-JWs will use that very same methodology to refute the borg and the Bible.
When butting heads with a fundamentalist, this method is justifiable insofar as it demonstrates that one literalist's interpretation is just as valid as the other's. But when seeking to discredit the Bible as a providential collection of inspired texts, to lean upon this method only demonstrates that one has not yet recovered completely from the mental atrophy of the WBTS coma. With many examples in the Bible to show this, scripture was never meant to be interpreted without an accompanying tradition of teaching. Jesus, while citing scriptures throughout his ministry was not satisfied with a mere reading of it, but offered deeper insights than could be gleaned from the text. If appealing to Jesus seems unfair, then take the example of Paul, for whose teachings there are no precedent as established by Christ--and it would be ignorant to think that Paul's epistles contain EVERYTHING that he taught during his ministry. And finally, the Bible shows us Christ as establishing the Church and the apostles founding supporting Churches as institutions of a living tradition of teaching. The point, which fundamentalists are reluctant to grasp, is that a book although Divine and inspired is not intended to support itself. So, if I may offer some advice to the many who still walk with a fundamentalist's limp, you need the aid of more than the strict letter of the Biblical text if you want to have a thoughtful discussion.
