The Eternal Son

Robert Letham's The Eternal Son offers a sustained theological and historical treatment of the person of the Son within the Trinity, arguing that Christology is central to the Christian faith.

The book traces ecumenical debates—especially the often-neglected councils after Chalcedon—showing how questions about the Son's person affect soteriology and doctrine.

Letham defends the orthodox position that the eternal Son assumes a true human nature without change to his divine person and critically engages modern biblicist and revisionist proposals.

He includes pastoral implications, discussion of adoption and atonement, and appendices addressing contemporary confusions.

The work is written for pastors, scholars, and students concerned with reclaiming historic Trinitarian and Christological clarity.
