To the OP : Also look into Captives Of a Concept by Don Cameron.
You touched on this briefly with 'new light' of Prov 4:18 and how it ties in to Math 24 :45-47 and the Faithful and Discreet slave. This was a rhetorical question posed by Jesus and was not meant to point to any one particular group. The WT don't have a leg to stand on once this is shown. I believe they did this for 'unity at all costs' and even though their reasons may of been honorable at one point long ago, they certainly no longer are.
Oh and the 'well where will we go, you have saying of everlasting life' spoken by Peter. Well the answer to that is Jesus Christ himself, not the 'organization' that claims to be Jehovah's organization. Actually when you stand back and look at it there whole way about upholding themselves is childish, immature and reminds me of schoolboy behavior and bullying.
