What religious services are traditional and structured?

Traditional and structured religious services often include a set order of worship, such as prayers, hymns, readings from sacred texts, and sermons. For example, Christian liturgical services, like those in Catholicism and Anglicanism, follow a specific liturgy, while Jewish services often include prayers and Torah readings. Additionally, Islamic services, particularly during Friday prayers (Jumu'ah), follow a structured format that includes a sermon (khutbah) and congregational prayers. These services emphasize communal worship and adherence to established rituals.
