My son-in-law and his family are/were. He says it is a cult. He and half his family have been ostracized. They only see the other half when the other half disregards the "shunning" they are supposed to do to the oscracized. He has 4 grandchildren of his parents which puts them in a tight spot.
I cannot tell you all the details of why he says it is a cult but I can tell you the pain he and his family have over how they were treated by the JW congregation is very real. My daughter essentially has said it has left him a shell of a man, unsure of his convictions and eager to avoid conflict stemming from those convictions.
There are always two sides to every story Wrangler....the shunning is scriptural, (1 Corinthians 5:9-13) and it is only applied when serious wrongdoing is confirmed and the person is completely unrepentant. (1 Timothy 5:20) Their attitude and conduct make them unfit company.
"A little leaven ferments the whole lump"....which is why they are disfellowshipped, (2 John 9-10) to protect the rest of the congregation.
If we make a vow to God, he expects us to keep it. We know the rules before we apply for baptism, so to us, it is a more serious commitment than a marriage. Its not something where you just decide to change your mind and walk away. It is seen as a defection.
You cannot join Jehovah's Witnesses....you have to choose to
become one.....this is after a thorough study of the Bible, which is not undertaken superficially. If you don't do the wrong thing, you don't have to endure the discipline. How can you complain about the discipline if you signed up knowing full well that if you break the rules, it will be administered? (Hebrews 12:11)
A vow to God is not to be taken lightly.....so we don't. But the door is never closed.....a repentant one will be welcomed back after appropriate and loving counsel is given. Some of my own family members have been disfellowshipped and have come back to the fold, humbled and grateful for the discipline....others have had their pride injured and just get angry. It shows us who we really are at heart.
