Abstract: This dissertation is a study of the Trinitarian theology of creation in Louis Bouyer. The goal is to systematize Bouyer's thearcian triadology and sophiology. It is argued that Bouyer employs these theological perspectives in order to put anthropology, cosmology and ecclesiology into the perspective of a pronounced Christological and Trinitarian ontology. A central argument is found throughout: that Bouyer connects the elements of Christian dogma by showing the inextricable connection of humanization, cosmicization and divinization. Moreover, and connected, it is argued that for Bouyer finite being and becoming can have no other plausible ground except in the eternal, Trinitarian perichoresis. Bouyer's theology of creation is expressed by means of a theological ressourcement and attention to modern insights in philosophy, philology, science and aesthetics. The dissertation proceeds by first showing the historical context of Bouyer's 'Trinitarian panentheism,' then by examining it in all its aspects. Bouyer's 'cosmological anthropology' is first explored. Next, the connection of this cosmological anthropology is made to his theology of the Trinity. The study concludes by drawing out some of Bouyer's themes in connection to other modern theologians whose concerns are similar to those of Bouyer.
