What is the officiant of a Christian Science funeral rite called?

In a Christian Science funeral rite, the officiant is specifically referred to as a Christian Science officiant. This title reflects the unique beliefs and practices of the Church of Christ, Scientist, which focuses on the spiritual understanding of life, healing, and the continuity of existence beyond physical death. The officiant guides the service in accordance with Christian Science principles, which may include readings from the Bible and Mary Baker Eddy's writings, as well as prayers that emphasize spiritual healing and the idea of immortality.

The other options refer to officiants from different denominations that have distinct rituals, teachings, and approaches to funerals. A Roman Catholic officiant is associated with the traditions of the Catholic Church, a Mormon officiant serves in accordance with the beliefs of the Church of Jesus Christ of Latter-day Saints, and a Protestant officiant typically pertains to various mainstream Protestant denominations. Each of these has different theological foundations and practices that do not align with the specific structure and philosophy of a Christian Science service. Thus, the title of Christian Science officiant is not only correct but crucial for accurately representing the context of the funeral rite in question.
