No, that’s not what the CHI says. The CHI says that IF a formal Church disciplinary proceeding is held, then . . . But there’s no requirement that a disciplinary hearing be held at all in response to a criminal conviction, unless the conviction is for murder or incest. A criminal conviction for DUI can be handled by informal counseling and/or informal probation by the person’s bishop and go no farther than that. The decision to hold a formal disciplinary proceeding would not be based on the DUI conviction, but on the person’s history of Church-related problems (e.g. “Word of Wisdom” problems, such as drinking alcohol, with no legal action). If the Church response to Killpack’s DUI is informal counseling and informal probation under the direction of his bishop, then the duration of any restictions are also entirely at the discretion of his bishop. If his bishop requires him to turn in his temple recommend for 6 months and attend Church-approved alcohol counseling, then that’s all that happens, and the Bishop is free to give back his recommend at the end of 6 months (or even earlier if the bishop changes his mind). No formal Church Discipline proceeding >> no connection between legal status and Church status.
Unless the offense is grave enough to bring bad PR onto the lds - sufficiently vague to cover a multitude of sins.
