Who typically assists the priest at an Eastern Orthodox service?

The correct answer is that a cantor typically assists the priest at an Eastern Orthodox service. In the context of Orthodox liturgy, the cantor plays a crucial role in leading the congregation in hymns and chants during the service. This includes singing responses to the priest's prayers, chanting the readings from Scripture, and guiding the congregation in the liturgical music that is an integral part of Orthodox worship.

The position of the cantor is significant as it enhances the spiritual atmosphere of the service and helps to convey the theological messages embedded in the music. By performing these duties, the cantor supports the priest and contributes to the overall worship experience, aligning closely with the traditions of the Eastern Orthodox Church, which places a strong emphasis on music and liturgical celebration.

In contrast, while a celebrant refers to someone who leads a liturgical ceremony, typically in a broader Christian context rather than being specific to the Eastern Orthodox Church, a cardinal usually holds a position of authority in the Roman Catholic Church, and a pallbearer is someone who carries a casket at a funeral, none of which relate directly to the role that assists the priest in an Eastern Orthodox service.
