This second edition of the bestselling Orthodoxy & Heterodoxy is fully revised and significantly expanded. Major new features include a full chapter on Pentecostalism and the Charismatic movements, an expanded epilogue ("Relations with the Non-Orthodox") and a new appendix ("How and Why I Became an Orthodox Christian"). More detail and more religions and movements have been included, and the book is now addressed broadly to both Orthodox and non-Orthodox, making it even more sharable than before. For reference, the first edition was called Orthodoxy and Heterodoxy: Exploring Belief Systems Through the Lens of the Ancient Christian Faith Are you an Orthodox Christian who wonders how to explain to your Baptist grandmother, your Buddhist neighbor, or the Jehovah s Witness at your door how your faith differs from theirs? Or are you a member of another faith who is curious what Orthodoxy is all about? Look no further. In Orthodoxy & Heterodoxy, Fr. Andrew Stephen Damick covers the gamut of ancient heresies, modern Christian denominations, fringe groups, and major world religions, highlighting the main points of each faith. This book is an invaluable reference for anyone who wants to understand the faiths of those they come in contact with as well as their own.
