The Comforter Quotes

“Cyril of Alexandria, even more than St. Epiphanius, can present difficulties for the polemicists with the Catholics and lend support to the Filioque partisans, for it is his wont not only to call the Holy Spirit proper, idios, to the Son, in all the ambiguity of this expression, but also to speak of the origination (proeisi) of the Holy Spirit from the Father and the Son, or even from 'Both'.”
― Sergius Bulgakov, The Comforter
