Deification penetrates all spheres of human existence, and can be seen as an answer to most pending ultimate questions. It is essentially practical in its manifestation and uplifting in its content, but nevertheless, always evasive and arcane in its comprehension. Aimed both at those who are already students of theosis and at those who are looking for an introductory text, this book contains biblical and historical-theological essays that offer innovative approaches to the issue of theosis the transformation of believers into the likeness of God. The interconnection between deification and the doctrines of the Trinity, Christology, anthropology, protology, hamartiology, soteriology, and eschatology are made manifest in these fascinating new studies.
