Book excerpt: This new 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, 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.
