The complex nature of Christian communion with a personal God requires a nuanced expression. Since its inception, the early church affirmed God’s unknowable nature and also participation in God through Christ. The church fathers employed the language of theosis in talking about union with God and human transformation in the likeness of God. However, the term theosis or deification is a broad category and requires precise explanation to avoid human dissolution into the divine in the mystical union it attempts to describe. In Triadosis, Eduard Borysov offers a new approach to the conundrum of the imparticipable divine nature and the prospect of personal union between human and the Trinity. Most significantly, he proposes that if God is Trinity, then we are created and restored in the image of the same tri-personal God.

Endorsements and Reviews

Borysov’s book adeptly summarizes recent work on patristics, Reformation studies, and modern Eastern Orthodoxy in order to provide guidance for our understanding of Paul’s concept of theosis or deification. His fresh analysis and his new term, triadosis, beautifully capture the most fruitful strand of thought on deification: human beings are meant to share in the relational life that characterizes the Father, Son, and Spirit. I recommend this book enthusiastically.

Borysov’s study does a marvellous job in exploring the Trinitarian dimensions of theosis in Pauline interpretation in church history. The strength of this monograph lies in its probing survey of the fathers, the reformers, and modern theologians, orienting the reader to a multi-faceted treatment of the topic through Trinitarian lenses. Borysov’s work is an important contribution in the re-appropriation of theosis as interpersonal communion with the triune God, who transforms the faithful into the likeness of the tri-personal divine community through grace.
Ashish J. Naidu, Associate Professor of Theology, Talbot School of Theology

A rich study that rewards the reader over and over by its clear engagement of vast theological and historical themes. Eduard Borysov offers us a compelling account of the summum bonum of our transformation and union with God that is robustly Trinitarian, biblically faithful and wise in the present currents of Pauline scholarship.
