Re: The Cloud upon the Sanctuary
The "insular rings" style of organization is not the paradigm given for the body of Christ. There is no secret inner circle in the Kingdom of God, after the manner of occult organizations.
There is, however, the requirement to keep secrets or certain information confidential, but that does not constitute an inner sanctum in the church.
Jesus said that not everyone was ready for the inner teachings; he did not give the deeper revelations to those who were not prepared for them - this is a matter of spiritual maturity and individual relationship with God (i.e. Rema).
