New Liturgical Handbook Illuminates the Heart of Orthodox Worship

INDIANAPOLIS — A groundbreaking new resource for Eastern Orthodox Christians has been published, offering clergy, laity, and inquirers an in-depth yet accessible guide to the Orthodox Church’s divine services. Titled “The Divine Services of the Orthodox Church with Commentary," this comprehensive handbook combines original translations of liturgical texts with rich theological explanations, patristic insights, and practical pastoral applications.  It is perfect for private liturgical study but is geared for use in the pew.  

Authored by three distinguished priests and scholars—Fr. Joshua Genig, PhD; Fr. Lucas Christensen, PhD; and Fr. Patrick O’Grady, PhD—the book serves as a catechetical companion to the Orthodox liturgical cycle. It functions as an “Orthodox hand missal,” helping readers delve deeply into the theology, symbolism, and spiritual meaning of the services that form the core of Orthodox Christian life.

Key features of the volume include:

• Detailed explanations of major services, including Vespers, Matins, the Divine Liturgy, the Holy Sacraments, and festal observances.
• Integrated patristic commentary alongside practical pastoral insights for contemporary application.
• Dedicated sections exploring how the liturgy shapes Christian living and counters modern secular distractions.
• Full liturgical texts with rubrics, plus catechetical questions designed for personal reflection, group study, or parish education.
• Original translations of the liturgical texts for clarity and fidelity.

Endorsements come from prominent figures, including Metr. Sevastianos of the Greek Orthodox Archdiocese of Atlanta, Archimandrite Joseph of St. Gregory Palamas Monastery in Ohio, and the V. Rev. Fr. Bartholomew Mercado, Professor of Canon Law at Holy Cross School of Theology. Metr. Iakovos of Mexico, Exarch of Central America and the Caribbean Islands for the Ecumenical Patriarchate, praised the work in a letter of endorsement:

“From its opening pages, this book unveils a treasury of wisdom, weaving together the beauty of our liturgical tradition, the depth of patristic theology, and the radiant hope of the Gospel... It is a rare gift to encounter a text that so harmoniously balances scholarly insight with spiritual warmth, making it an invaluable companion for the sacred liturgy and communal study.”

The authors intend the book to foster liturgical renewal in Orthodox parishes and serve as an inviting resource for those exploring Eastern Christian worship.

The volume is available in both full-color and grayscale editions, with all profits supporting the authors’ ministerial work. It can be purchased on Amazon, with the full-color edition available here, and the grayscale edition available here.

Published by St. Symeon of Thessalonica Press (December 2025), this 452-page hardcover is poised to become an essential tool for deepening appreciation and participation in Orthodox divine services.
