2016 Wesleyan Discipline: 678
678. A minister who serves as the sole pastor of a church shall be referred to simply as “the pastor.” The term “senior pastor” shall be applied to the presiding minister of a multiple pastoral staff. The pastor shall be expected to carry out the full pastoral function as set forth in 2016 Wesleyan Discipline:675, and ultimate responsibility for the same shall rest upon the senior pastor. An associate pastor is a helping member of a multiple staff who normally shares a broad range of the shepherding and teaching responsibilities and such administrative responsibilities as are delegated (cf. 2016 Wesleyan Discipline:738). An assistant pastor is a helping member of a multiple staff who normally is assigned more limited and specific aspects of the pastoral function (cf. 2016 Wesleyan Discipline:741).
