After the publication of the Prologue, the A' and B' Books of the Antirrhetic Treatise by John V' Kantakouzenos Against the heresy of the Palamites by John Kyparissiotes, this volume presents the C' Book of the extensive treatise, which aims to complete the effort of the crowned scholar and theologian to defend the patristic and primarily Palamite theology.

This is an autonomous text that focuses on the nature of the light of Tabor, on its relationship with the light that the hesychasts saw during their prayer, and highlights the uncreated nature of the divine light, which belongs to the divine and not to the human nature of the Lord.

This edition captures all the Palamite and anti-Palamite theology of the era regarding the nature of the Tabor light, while simultaneously tracing indirect influences from other contemporary and earlier texts, demonstrating their interaction in the context of the hesychastic controversy.
