What is a Hieromonach in the Eastern Orthodox Church?

Hieromonach (Greek: ιερομόναχος, ierosmonachos) is a title used in the Eastern Orthodox Church to refer to a monk who has been ordained to the subdiaconate and serves as an assistant to a bishop or abbot. The word "hieromonach" is derived from the Greek words "hieros" (sacred), "monos" (alone), and "akhos" (leader).

In the Eastern Orthodox tradition, hieromonachs are typically chosen from among the monks of a monastery and are ordained to the subdiaconate by the bishop or abbot. They serve as assistants to the bishop or abbot in various capacities, such as leading prayers and liturgies, preaching sermons, and performing other sacramental rites. Hieromonachs may also be responsible for overseeing the spiritual and material needs of the monastery and its members.

The title of hieromonach is considered to be a mark of distinction and honor within the Eastern Orthodox Church, and it is typically bestowed upon monks who have demonstrated a high level of devotion, wisdom, and spiritual maturity.
