2016 Wesleyan Discipline: 503
From Wesleyan Discipline
503. A pastoral charge may consist of a single church, or of two or more churches designated by the district conference as a circuit; is supplied as a regular pastoral appointment by the district conference; and transacts business through a local conference of the covenant members. The constitutional rights of a pastoral charge are given in 2016 Wesleyan Discipline:315. If the district conference desires to appoint a minister to serve two or more churches that shall continue as separate pastoral charges, it may appoint the minister as pastor of one church and supply pastor of the other (2016 Wesleyan Discipline:3255–3260).
