5023:5

(5) Dismissal. Dismissal is the strongest discipline and is the expulsion of the offender from membership in the Church (Disc. 305:3; 315:1; 585:3), which automatically includes all lesser disciplines. Dismissal should be imposed only for the most serious offenses, or for obstinate persistence in a serious offense. (See 2 Cor. 6:14–15; 1 Tim. 1:19–20.)
