ABOUT THIS BOOK<\/div>\n

<\/div>\n<\/div>\n

A Catholic-Orthodox dialogue in book form. Dave Armstrong\u2019s apologetic for Catholicism and respectful critique of Orthodoxy, with significant additional contributions from Byzantine Catholic Fr. Deacon Daniel G. Dozier \u2014 feedback, reply, and a closing chapter from the Eastern theological perspective.<\/p>\n

[First Edition completed in July 2004; published by Lulu in August 2007; Third Edition (heavily revised), with additional contributions from Eastern Catholic Fr. Daniel Dozier, was completed in July 2015; 335 pages]<\/p>\n

It has been my strong desire for some time now to revise my book in order to emphasize ecumenism and unity proportionately a lot more than in the first (2004) edition. I\u2019m much more interested in finding common ground. I\u2019ve also learned a thing or two about Orthodoxy over the past decade. I wanted this volume to be able to read by Orthodox and also Eastern Catholics, without having seizures or going into apoplectic fits (caused by my ignorance or overly polemical or biased writing). I exaggerate, of course, but perhaps not by much! Toward that end I have enlisted a very qualified Eastern (Byzantine) Catholic friend to participate in the revised edition: Fr. Deacon Daniel Dozier. The revision remains an apologetic for Catholicism and respectful critique of Orthodoxy, but now it also includes friendly ecumenical discussion and dialogue: feedback and input from the Eastern theological perspective. The overall tone, tenor, and goal is considerably different. Unity is stressed as much as apologetics. <\/p>\n<\/div>\n<\/details>\n<\/div>\n
