Liturgics

Oversimplified

• The study and practice of the Church's worship — the Divine Liturgy, the daily services, the sacraments, feasts, and the yearly cycle.
• For Orthodoxy worship is not one activity among others but the Church being most fully herself: heaven on earth.

Summary

Liturgics concerns the leitourgia ("public work") of the Church: above all the Divine Liturgy of St. John Chrysostom (and of St. Basil the Great), together with Vespers, Matins, the Hours, and the sacraments. The services are woven from Scripture — especially the Psalms — and structured by the daily, weekly, and yearly cycles centered on Pascha.

Worship as theology

"The law of prayer is the law of belief": what the Church prays, she believes. The Liturgy is where doctrine, Scripture, and communion meet, and where the faithful stand already within the Kingdom, offering the Eucharist in thanksgiving.[^1] See Eucharist, The Psalter, Iconography.
