I was invited twice. So I didn't attend twice. But I did turn up over an hour before the 2nd one was due to be held and told them they had no right to do this and that I did not recognise their authority, nor did I recognise them as Jehovah's Witnesses and I told them their behaviour was appauling and that they all ought to be ashamed of themselves.
Before this I also turned up to an elders meeting with letters detailing pretty much the same as above. There were probably about 16 or 17 men at this elders meeting and they were unwilling to come to the door. I sensed the one who opened the door was even trying to pretend it wasn't an elders meeting so they could all hide. But I made it clear that I knew what was going on and invited them to step outside. Only 3 did and they didn't linger.
Anyway they had no Christian authority so effectively they've done nothing to me in relation to anything scriptural. Except they have proved themselves to be a bunch of lying, bullying, apostates.
