CoCo...that is a great question, and one I have wondered about for years. I have never heard an answer to the question of how the very "councils" that finalized the canon of the Bible as we know it today, could also be the "councils" of the era that affirmed the Trinity and Immortality of the Soul doctrines. How can they be inspired in one endeavour and then promoters of false religious teachings in another?? This has always seemed a contradiction, but I have never heard anyone actually challenge the WTS's position on this...it certainly makes one think!
