The classic and definitive guide to Eastern Christianity. This comprehensive guide to the history, theology, worship, and spirituality of the Orthodox Church makes it a key reference for both Christians and general readers seeking to understand the roots and beliefs of this tradition. Written in accessible language, the book is highly recommended for anyone seeking to explore the rich spiritual heritage of Eastern Christianity. The book is divided into two main sections: history and faith and worship (theology & spirituality). The first section traces the journey of the Orthodox Church from its origins to the modern era. It covers (a) ancient roots (the birth of Christianity in the East and how the church has maintained the faith through the ages), (b) the Great Schism (the separation of the Eastern Orthodox Church from the Roman Catholic Church in 1054), and (c) regional developments (the history of the Orthodox Church in Russia and Greece, and its spread throughout the world). Meanwhile, the second part explains in detail the beliefs and practices of Orthodox people, such as (a) dogma and councils (explanations of the seven ecumenical councils that form the basis of the Orthodox faith), (b) sacraments and worship (the deeper meaning of the sacraments as well as the life of prayer and spirituality), (c) theology and teachings (Orthodox views on the trinity, free will, salvation (theosis), and relations with western churches (Catholic & Protestant).
