In the Moscow and St. Petersburg of the late nineteenth century, and later in Parisian exile, Vladimir Soloviev, Nikolai Berdyaev, Sergei Bulgakov, Pavel Florensky, and Mother Maria Skobtsova reimagined Christian thought from within the Russian spiritual tradition. When the Revolution scattered them, they carried their conversation to the Saint Sergius Theological Institute in Paris, where the tradition continued in diaspora.
