I am seeking a complete and authoritative explanation of this issue.
Who presides at Sacrament meeting (common Sunday services) when the bishop of a ward (pastor of a local congregation) is unavailable? There are several circumstances that should be considered when answering this question. The best answer will cite both the handbook of instructions and scripture to justify the explanation. Linking back to Church resources is appreciated.
When any higher authority is easily accessible and...
- When the Bishop (perhaps due to illness) is suddenly unavailable.
- When the entire bishopric is unavailable, but the absence was expected.
- When the entire bishopric is unavailable, but the absence was unexpected.
When all higher authorities are also unavailable and...
- When the Bishop (perhaps due to illness) is suddenly unavailable.
- When the entire bishopric is unavailable, but the absence was expected.
- When the entire bishopric is unavailable, but the absence was unexpected.
A bonus would be an explanation of what priesthood keys (or priesthood authority) is NOT available when any or all of these circumstances take place. As an example (and as a hint), if the bishop and all higher authorities are unavailable, non-priesthood disciplinary councils cannot be convened.
