The sophiology of Sergius Bulgakov has exerted a significant amount of influence over Anglophone theology over the last decade. Theological figures as significant as Rowan Williams, John Milbank and Paul Fiddes, to name but a few, have positively engaged with and utilised Bulgakov's sophiology within their own theological contributions. Thus, for many, Bulgakov's sophiology has proven to be a fecund source of theological inspiration, especially when articulating the relationship between God and the world. However, historically, Bulgakov's sophiology has been criticised by many Orthodox theologians, who argue that Bulgakov's proposals are theologically flawed and challenge traditional orthodox readings of Christian doctrine. Despite the controversy surrounding Bulgakov's use of Sophia, very few comprehensive, critical studies of Bulgakov's sophiology, spanning its historical development, exist. This article seeks to fill this void at a time when Bulgakov's sophiology is enthusiastically adopted by many without an accompanying critical lens.
