Each synod shall delegate some to execute everything ordained by synod, both as to what pertains to the government and to the respective classes resorting under it, and likewise to supervise together or in smaller number all examinations of future ministers. And, moreover, in all other eventual difficulties they shall extend help to the classes in order that proper unity, order, and soundness of doctrine may be maintained and established. Also they shall keep proper record of all their actions to report thereof to synod, and, if it be demanded, give reasons. They shall also not be discharged from their service before and until synod itself discharges them.
