Existing manuals – already required of presbyteries, synods, and the General Assembly, and in use by many sessions – remain in force until changed by a council. Revisions do not have to be made immediately, affording a council time to determine what structures and procedures will work best to carry out its identified mission for Jesus Christ. The Advisory Handbook for Councils for the Development of Policies and Procedures [hyperlink] identifies policies and procedures required by the new Form of Government for each council, most of which should already be in place and would be revised only if and when a council deems it necessary.
