Ray Franz' view overall appears to be that we stay one in loving conduct toward each other. He has no problem over you or others believing in the trinity, Nathan, besides, various trinitarians also have different views of what the trinity is. Nor does he worry if people feel holy spirit is a person, spirit being or idea. But he believes in unity by love which Colossians says is the strongest bond, not compulsory beliefs on all things.
Christ also emphasized basic principles like love, joy and peace while the Pharisees and Saducees put more emphasis on rules and rigid interpretations of scriptures than love. So I think Ray Franz is correct although like yourselves I also also that he is also sometimes incorrect. Diversity is good, and he appears to agree with that. All trees are not the same kind, nor are all flowers. Why would God or any sane human try to force same beliefs on all topics? God brings sunshine, rain and other kind gifts to us all and as much as possible we need to show kindness too.
My main concern is that elders all over have been totally misinformed about the man. Shame on those doing that. Let them remove the rafters from their own eyes.
