Neighbouring churches shall come together in a classis by delegating a minister and an elder, or if a church has no minister, two elders. Classis shall convene at least once every six months in person. The ministers shall be chairman in rotation, or one shall be chosen to be chairman; however the same minister shall not be chairman twice in succession. The chairman shall ask whether the ministry of the office-bearers is being continued, whether the decisions of the major assemblies are being honoured and whether there is any matter in which the consistories need the judgment and help of classis for the proper government of their church. Every classis shall determine where and when the churches shall meet again. The last classis before synode shall choose delegates to that synod.
