Written by Protopresbyter Thomas Hopko, the series 'The Orthodox Faith' is intended to provide basic, comprehensive information on the faith and the life of the Orthodox Church for the average reader. The four volumes (all on-line) cover Doctrine, Worship, Bible and Church History, and Spirituality.
