The last book of Father Sergii Bulgakov, "The Apocalypse of John", can be considered the conclusion of his work as a whole. Written "in the face of the very apocalypse of life" during the Second World War, Bulgakov's commentary is not focused on trepidation before final judgement, but reflects deeply on the possibility of hope in the midst of the tragedy of human history, and joy at the prospects of God's final triumph, the transfiguration of creation: it is "the divine story of the victory of the Lamb".
