Can anyone seriously imagine any member of the current GB standing up and reading a Resolution seeking Jehovah's forgiveness for any errors within the organisation? Or printing such in a Watchtower article (or today's equivalent - making a statement from behind that fancy desk at JW HQ on a monthly broadcast?)
From my own understanding in the land Downunder, my take is that it was not a mea culpa by the GB (WTleadership) of the time but rather derived from a reprimand of the local i.e. Australia branch, leadership during a visit to the branch.
