What literary work did John Chrysostom write that outlines the service liturgy?

The Divine Liturgy, attributed to John Chrysostom, is a foundational text that outlines the structure and elements of the Christian service liturgy. This work provides a comprehensive guide for the celebration of the Eucharist and incorporates various prayers, hymns, and rituals integral to the Orthodox Christian worship practice.

Chrysostom's contribution is particularly significant as his liturgical formulation is still used in many Eastern Orthodox churches today. The Divine Liturgy reflects theological ideals and pastoral concerns of the early church, illustrating how worship is meant to be both a communal experience and a profound encounter with the divine. This work's emphasis on prayer, the reading of Scripture, and the sacraments underlines the importance of liturgical worship in fostering a sense of community and spiritual growth.

Other works mentioned, such as Ecclesiastical History, Golden Homilies, and Sermon on the Mount, have their own importance but do not specifically focus on outlining the service liturgy as the Divine Liturgy does. Each of those works serves different purposes, like chronicling church history or presenting moral teachings, but they do not provide the liturgical framework that is the hallmark of the Divine Liturgy.
