What term describes the officiant at a funeral service for the Church of Jesus Christ of Latter Day Saints?

In the context of the Church of Jesus Christ of Latter-day Saints, the officiant at a funeral service is referred to as a "Speaker." This designation aligns with the practice within the church where individuals may be called as speakers for various occasions, including funerals.

The role of the speaker is to provide comfort, share messages of faith, and often recount the life of the deceased. Typically, the speaker is not a designated clergy member but rather a member of the faith community who has been asked to fulfill this important role during the service.

The other terms listed in the question typically refer to officiants in other religious contexts. For instance, a reader may conduct readings but lacks the specific connection to Latter-day Saint practices concerning funerals. A practitioner could refer to an individual involved in religious or spiritual practices more broadly, but again does not embody the specific tradition of the Latter-day Saints. Lastly, a rabbi is a religious leader in Judaism, which makes them relevant in that faith but not in the context of a Latter-day Saint funeral service.

Thus, "Speaker" accurately captures the function and title of the officiant within the specified religious tradition.
