2016 Wesleyan Discipline:3260:2

(2) A supply pastor shall be appointed temporarily to fill the pulpit and to provide a spiritual ministry, but shall not have authority to administer the sacraments or to perform marriages unless that authority adheres on some other basis, and shall not perform the administrative function of the pastor except in filing of reports unless authorized to do so by the district superintendent (cf. 2016 Wesleyan Discipline:1310:8, 23). If a supply pastor is serving a congregation isolated from Wesleyan ministers, making it difficult to provide for administration of the sacraments (2016 Wesleyan Discipline:725:6), the district superintendent may grant the supply pastor special authorization to administer them.
