Just what exactly am I missing here?
Elders get confessed tosummon the acccused to a mandatory interrogation, priests get confessed to voluntarily--they have no power to compel a confession.
Elders enjoy privileged information which is known to multiple elders on the judicial council and to witnesses who testify before the council, which becomes fodder for gossip when an announcement is made to the congregation; priests enjoy privileged information known only to them and the penitent, and they are forbidden to reveal even the existance of such information to anybody (even if their silence means going to prison).
Elders get orders from Bethel as spelled out in the top-secret elders manual and letters from HQ that most members are forbidden to see; priests get orders from published encyclical letters and the code of canon law, available for anybody to see and read (clergy, layman, and non-Catholic alike)--the same rules which apply to all members of the Church, including the Vatican.
