What is the proper title for an officiant in the Christian Science faith?

In the Christian Science faith, the proper title for an officiant is "Reader." This title reflects a distinctive aspect of their worship services, which typically feature readings from the Bible and the works of Mary Baker Eddy, the founder of Christian Science. The Reader is responsible for conducting the service by reading these texts, which form an important part of the worship experience for congregants.

In Christian Science, there are usually two Readers: one handling the Lesson-Sermon, and the other serving as the Second Reader. This format emphasizes the community's engagement with scriptural and spiritual texts rather than a traditional ministry model where a minister might lead the service.

The other titles—Minister, Deacon, and Pastor—are generally associated with more conventional Christian denominations and imply roles that might involve ordination and sacraments, which do not align with the structure and practices of Christian Science.
