A lot of the jw defence is mearly semantics. If it gets tough you could try qualifying what the definition of prophet is. They admit that the GB inturprets words and "signs" to predict the future. They have stated future events with dates. There are NO dates in the bible. 1914 is nowhere.
Ask them if bible charactors who interpreted dreams were prophets. The bible is inspired by Jehovah, but those dreams were inspired by Jehovah as well. It's the same thing. So, if those dream interpreters were prophets by using the holy spirit to interpret dreams to predict the future, the same can apply to the GB by using the holy spirit to interpret Jehovah's words to predict the future. Remember, the number 1914 is nowhere in the bible.
This is very different to say a stock broker or sports commentator predicting the future. They use form and intuition to make an assumption. The GB doesn't make assumptions . So, if its not assumptions to say what IS going to happen in the future ESSPECIALY when siting dates, it sound to me like prophecing.
However, if you end up getting a juditial commitee, you will not win. You will be given two choices. The same two choices religions have been giving for hundreds of years. Repent of your sins and accept the church or die (spiritually die and familly communications die) . If you want to stay in good communication with your mom you'll probably have to back down.
I posting this to let you know that I believe your argument to be correct, and strong. You are right. There is a bigger picture than argument with this sect, and that's your relationship with your mom. And for that I do not envy your position. Many of us on this board have been through similar situations.
Please keep us updated on your progress, and ask for help here whenever you need it.
Keep strong.
