Presbyter Councils, Deacon Councils and Missional Councils all employ the administrative convention of an Executive Team when the number of members of a Council exceeds 12. The practical reasons for this are that human communication and coordination dynamics become so complex in groups bigger than 12 that the contributions of some individuals become diminished as the contributions of others are elevated over others, which either wittingly or unwittingly, leads to the formation of mediatorial hierarchies. When this happens by default or reactively, it tends to create mediatorial, non-covenantal dynamics in authority relationships, which undermines the group relationally and in its effectiveness. Therefore, Basileia proactively utilizes Executive Teams with Councils of more than 12 members.
