Abstract

The theological formulation of the “eternal manifestation of the Spirit through the Son”, developed by the patriarch of Constantinople Gregory of Cyprus in the 13th century, has been the subject of numerous studies in the 20th century and played an important role in the renewal of Trinitarian Orthodox theology. The interpretations are however diverging. Most theologians see in this formulation the manifestation of the uncreated energy, which would have been formalized later by Gregory Palamas. Others understand it as a hypostatic reality concerning the third Person of the Trinity. This paper contributes to the discussion by re-analyzing the main texts of Gregory of Cyprus and of Gregory Palamas on this matter. In a first step, we defend the thesis that in the thought of the Byzantine patriarch, this expression truly concerns the hypostasis of the Spirit. In a second step, we question the existence of the theme of an “eternal manifestation” of the uncreated energy in the work of Gregory Palamas.
