I am a free thinker and for me the bible not only has instructions on how to be true but can and will always be interpreted in many ways. this does not mean anyone can say the other is incorrect.
Whereas the JWs believe that the interpretation of the Bible published by the Watchtower Society is the only correct one (that is, until the Society changes an interpretation to a newer one).
They believe that the Watchtower Society (or rather, the "faithful and discreet slave" that uses the Society) is the means through which God explains the true meaning of the Bible. If you become a JW, you cannot doubt this or you would be thought to be an apostate. If you become a JW, you must accept what the Watchtower Society teaches and teach these "truths" to others.
We are getting closer to a united church... there will always be sepretists and people who choose to follow on different paths and this neither wrong or right.
The Watchtower Society condemns ecumenism and interfaith. If you join the JWs, you will be expected to believe that only the path of the JWs is the correct one.
And for this they should not be knocked in fact i implore all those who have been involved with the WT in the past to be more tolerant in a true christian manner.
They are however not tolerant of those who can no longer believe what the Watchtower Society teaches, such as a child who was raised as a JW who never had the kind of experience you had of exploring Catholicism, Islam, and other religions. If someone who was raised a JW wants to explore other faith, he or she would very often be shunned and certainly be strongly discouraged from believing differently from what the organization teaches. There is no tolerance for freethinking and expressing yourself in a way that disagrees with the organization (if you have private thoughts that differ from it, you are supposed to keep those to yourself).
some of my intepretations will not nessacerily fall in line with the WT...But surely there love for me and for christians allows for this.
If you end up joining the JWs, you will have to shed these views that do not agree with the Society. You will be quizzed on your beliefs prior to baptism and when you are baptized you will have to affirm that you believe that the organization is directed by God as his channel. If there are beliefs you do not agree with, bear in mind that you will still have to publically teach the official doctrine and convince others of the correctness of it.
