 Lay people assist in the execution of the liturgy of divine services in numerous ways, as musicians, readers of the lections (not to be confused with "lay readers," above), intercessory leaders, and ushers (often called sidesmen or sidespeople).For many years some parts of the church have relaxed the official rules about lay ministry.Clergy often see their role as officiant and teach that the congregation are the ministers both in worship and through their daily work.
