When ministers, elders, or deacons have committed a public or otherwise gross sin, or refuse to heed the admonitions by the consistory with the deacons, they shall be suspended from office by the judgment of their own consistory with the deacons and of the consistory with the deacons of the neighbouring church. When they harden themselves in their sin or when the sin committed is of such a nature that they cannot continue in office, elders or deacons shall be deposed by the judgment of the above mentioned consistories with the deacons. Classis, with the concurring advice of the deputies of regional synod, shall judge whether the ministers are to be deposed.
