Some, like certain apostates today, are disloyally working as Satans agents to undermine the faith of newly associated members of the Christian congregation.(2 Corinthians 11:13)<quoted text>
Other Religions follow the bible; they do not make up their own.
Other religions follow the bible, they do not rewrite an established version of the bible retrofitting their theology into it.
Other religions follow the bible, they do not lie to their followers at to what the sources of their bible is.
Watchtowerism is a cult. It easily fits into any major definition of cult you are likely to find.
Rather than simply use the Bible as the basis for true teachings, they concentrate on trying to discredit the New World Translation of the Holy Scriptures, as if Jehovahs Witnesses were wholly dependent on it for support.
But this is not so.
For the best part of a century, the Witnesses used primarily the King James Version, the Roman Catholic Douay Version, or whatever versions were available in their language, to learn the truth about Jehovah and his purposes. And they used these older versions in proclaiming the truth about the condition of the dead, the relationship between God and his Son, and why only a little flock go to heaven.
Informed persons are also aware that Jehovahs Witnesses continue to use many translations of the Bible in their worldwide evangelizing work.
