This National Spiritual Assembly, which, pending the establishment of the Universal House of Justice, will have to be re-elected once a year, obviously assumes grave responsibilities, for it has to exercise full authority over all the local Assemblies in its province, and will have to direct the activities of the friends, guard vigilantly the Cause of God, and control and supervise the affairs of the Movement in general.
