anyone that can provide me current dumba** things that the witnesses have changed in the last say 15 years
I don't want to sound cynical, but I seriously doubt that this approach would make any difference either. You have to remember how Witnesses are indoctrinated to perceive these changes (or blunders). They have been very carefully trained to see these changes as proof that the organization is granted progressive understandings, or "new light" from Jehovah. They actually take pride in receiving these "changes", as they are constantly told that "Jehovah's chariot is on the move". By inference, this suggests that their teachings would also be "on the move" (i.e. wishy-washy).
I think that there are some very simple Biblical principles that are easy to approach, and which are very troubling to the JW doctrinal set. One of them is the concept of organizational salvation. Nowhere is there any hint in the Bible that salvation can come through (or be predicated upon) organizational membership. The Society's use of Moses and the Old Covenant priesthood as some sort of analogy to their organization simply does't fit. Only Christ is the "Greater Moses" (or mediator), and no person, "class" of people, or organization could ever serve in that capacity.
The JW baptismal requirements are also very dubious. The Biblical record is consistent in stating that people were baptized in the name of the Father, the Son, and the holy spirit. There was never any indication that one had to make a declaration of being baptized into any earthly arrangement, such as a particular congregation. The Watchtower Society in it's baptismal questions states that one must acknolwledge being baptized in association with Jehovah's spirit-directed organization (and by extension, in association with the Watchtower Society) before they can be considered having a right heart conditions for immersion.
Inform them that people in the first century knew exactly what it meant to be baptized in the name of the Father, Son, and holy spirit. Jesus himself never hinted that there must be this kind pre-requisite attached to baptism that the Watchtower Society requires.
Tell them that the requirement of acknowledging being baptized in association with an organization (or any earthly arrangement) is completely absent from the Scriptures and is a concept that was introduced into Christianity by the chruch councils. This requirement is still in practice by many of the churches of "Christendom" today. Ask your family how the Watchtower or JWs can criticize this practice in other churches, yet not criticize it within their own?
