EyesOpenHeartBroken, it is sad to hear that your father has passed away, it's not easy to deal with. I was fortunate enough to spend time with my father during his last months and I will never forget that as I imagine that is the same with you.
Thank you for sharing what he had to say. I will consider the book of John and James with your father's appreciation of them in mind.
Some posters have mentioned before that particularly amongst some of the older Elders there were/are some very special men. You're dad sounds like he was one of them. They knew of the flaws within the Organization, they saw it and experienced it on a level that most r&f members will never see. What kept them going was their love for God and they knew of no other way of feeling that they were serving him to the best of their ability. They were sincere and probably very disappointed at the many wrongs that they had seen.
Treasure the things that you learnt from him.
