It is the only way to get the flock to go along with present teaching, without complaint. There is no valid method of non-compliance without consequences. So, "Listen, Obey and Be Blessed" - the title of a new song from the songbook. Elevating oneself or a group is dangerous since there is accountability associated with it. Better it is for equality for a open exchange of ideas, expressions of valid complaints and true fellowship. Being responsible for the salvation and lives of the lowly ones is a sombering thought.
Can you imagine a suggestion box at the KH or at Conventions / Assemblies? How about solictations for individual thoughts on bible passages / doctrine? How about special interest group meetings? Ah, a community fellowship arrangement. It will never, ever happen.
