Popes John Paul II and Benedict XVI have called for unity of the Roman Catholic and Orthodox Churches. George Grube’s encyclopedia can help in this project. He holds graduate degrees in education, history, and theology from Trinity College, Washington, D.C., and the Angelicum in Rome. He wrote a two volume set entitled What the Church Fathers Say About …(1998), published by Light and Life Press. He also wrote The Orthodox Church: A to Z (2003), published, too, by Light and Life Press. This present book covers several topics in theology, history, and other topics \ with mostly short entries. Grube wrote most of these three thousand entries, but others, including Orthodox bishops, priests, and educators, also wrote some of the entries.

The Complete Book of Orthodoxy is a quick reference tool that would be of interest to Orthodox believers and to those studying the Orthodox Church. The entries are understandable, and occasional see-references help the reader locate what she or he is looking for. There are no footnotes or a bibliography; the inclusion of those would have helped readers wanting to learn more. Other than that problem, the book meets its purpose of being a quick reference on Orthodoxy.
