Iron Eagle,
Can anybody please help me and give me advice on what to say to him next time ... where in the JW publication does it say that , and what other points can I bring up ?
There are so many things you could point out to him. For example, while in Gen. 9:4 blood is forbidden, only animal blood is mentioned. Further, in 1 Sam. 14:32-35 the Israelites ate unblooded meat. Did they die for it? No, they had to make sacrifices to atone for it, but even after breaking an explicit command from God nothing else happened. (Compare this with those who murmured against Moses in the wilderness at Num. 16:1-50.) So why do they consider blood transfusions a df'ing offense?
The UN scandal--for decades they called it the Beast and criticized the Pope in a 1979 quote for saying the people of the world looked to the UN as the hope for the future. Yet ten years or so later, here they are dancing cheek-to-cheek with It, the highest example of Satan's power over the world.
Why were Witnesses in Malawi allowed to be tortured and die rather than be involved in politics, but Witnesses in Mexico were, from what I've read here, allowed to bribe officials to get party cards showing they were active in politics?
It's a proven fact Witnesses have been convicted and imprisoned for child molesting. Yet so often when it's been brought to the elder's attention, their response is to df the accusers ("creating divisions;" "casting reproach on Jehovah's name") and not notify authorities many times (as is required in some states here), citing 1 Tim. 5:19. How many times does someone molest a kid with witnesses to it?
Why is (or was) the WBTS listed as a majority stockholder in one company, which itself is a majority stockholder of another company producing a ceramic engine that the US military is very interested in for use in military transport vehicles? What kind of pacifism is that? And stock ownership--isn't that showing a lack of faith that "Jehovah will provide for the work," and when it stops that'll be the sign the end is near?
Do a search on here by keywords and you'll find other posts on the subject and where the proof can be found. And when he tries to steer you onto another topic, or make it all seem like a pack of lies because it's found on an "apostate website" (they use that word like conservatives here in the 1950's tarred political enemies with "Communist," "Red" and "fellow traveler" to name a few, as a convenient smear word designed to promote fear and disgust in the listener, not leaving them in a frame of mind to remember that "there's two sides to every story," and that "where there's smoke, there's fire"), stick to your guns and you'll get outright denials eventually. What else can he do? If he admits it that's going to send your faith right into the loo, and then he has to explain why he's stuck with the Society in spite of their past record.
A while back Jerry Bergman started a thread asking if some of us would be better off as Witnesses. Unfortunately the answer is yes. Some people have invested so much time, effort, and belief into the Society's teachings that when the house of cards falls their mental health will go with it or be dealt a severe blow. And/or they're so scared (ever notice how much FEAR is a central part of their belief system--FEAR of not living through Armageddon, FEAR of demons, FEAR of being kicked out/reproved, etc?), that all other religions are shot through with Satanic influences that they literally quake even considering going to another church.
Good luck.
