Surveying theological literature produced in the Christian East from the first through the 20th century, Eastern Christianity in its Texts explores different theological themes (analytical and mystical), genres (epistles, treatises, and poetry), and milieux (Greek, Armenian, Western and Eastern Syriac, Russian and Romanian).

The book illustrates the evolution of the Orthodox thought, how it influenced and was influenced by intellectual, social, and political environments. It demonstrates a theology in context, and yet displays consistency in the traditions spread through different epochs and countries.

The book is divided in five parts, each standing for an epoch with distinct features: formation of the Christian identity in the era before Constantine, golden age of theology in the period of Late Antiquity, the pinnacle of erudism and mysticism in the eastern Middle Ages, wrestling with the Modernity imported from the West in the 18th-19th centuries, and finally theological polyphony in the 20th century.
