II. The Assemblies of the Church
C. The Classis
The council of each church shall delegate a minister, an elder, and a deacon to the classis. If a church is without a minister, or the minister is prevented from attending, another elder shall be delegated in place of the minister. Officebearers who are not delegated may also attend classis and may be given an advisory voice.
