Anonymity isn’t evidence of incompetence. The Witnesses say the translators wanted glory to go to God, and Jason BeDuhn’s Truth in Translation rated the NWT favorably on several passages. Isn’t implying the work can’t be trusted an ad hominem?

BeDuhn is the strongest non-Witness defender of the NWT and deserves to be read; his praise is also qualified, since he criticizes the insertion of Jehovah into the New Testament, and other reviewers (Bruce Metzger, Daniel Wallace) were sharply critical. On anonymity, the careful wording is cannot be checked: anonymity does not prove bias, but it does prevent the ordinary check of examining the translators’ qualifications, and the names former members have given suggest limited training in the biblical languages. That is a reason for caution, not a verdict.
