Thank you all for your responses. I personally don't think they are deluded in so much as they know full well that they are changing a doctrine, change a word here or there = change the meaning, blame the RF if you believed what they told you (circa 1975), misinterpret to keep those believers in line, change the wording in the Bible to suit your teachings etc. If you read Franz's 'Crisis of Conscience', he states that most of the decisions were made without prayer; aka no discussion with God; so really, they know darn well what they are doing.
Again thanks everyone - oh and I really enjoy this site, so thank you to all who participate.
