ExB: Tonus which other organisations have love amongst themselves as Jesus said would be his true disciples?
I don't know. That is an interesting claim to try to measure. But this is a first step- does this give you confidence to consider them to have it right? You mention the changes in doctrine over the past 140 years. How does it affect your confidence in them?
JWs are not alone in ascribing changes to new insight provided by god, so they're not unique in making doctrinal changes over time. And if the changes they make do not align with that of other Christian denominations, perhaps it means they have it right. It still leads me to wonder if we should feel comfortable with a god who claims he is not a god of confusion, yet allows such confusion and misunderstanding to affect those who seek to serve him faithfully.
