The sixth chapter examines the patristic revivals of theosis in the early twentieth century by the Russian émigré theologians of the ’Paris School’, principally through the work of Myrrha Lot-Borodine, Vladimir Lossky, and the later Bulgakov. The first two of these writers engage with modern theologians partly to differentiate Orthodoxy from its new Catholic environment and partly (especially in Lossky’s case) to enable Western theology to enrich itself through interacting with Orthodox thinking.
