Eustratius of Nicaea, a Theologian: About the Recent Publications of Alexei Barmin

Being the most prominent philosopher and theologian of his epoch (late 11th-early 12th cent.), Eustratius of Nicaea provoked important theological discussions in the fields of both Christology and Triadology. He was eventually condemned (1117) for his Christological views, but his Triadology faced a strong opposition as well. His Byzantine opponents unfavourable to the Latins rejected his logically consistent approach to the Trinity and developed their own non-consistent (paraconsistent) approach, whereas his 13th-century latinophrone opponent Nicetas “of Maroneia” demonstrated that Eustratius’s logically consistent Triadology is more naturally compatible with the Filioque.
