Few of Sergius Bulgakov's professional writings achieve the lyrical heights of Jacob's Ladder. In it he discusses the doctrine of angels and their importance for contemporary humanity. He includes reflections on the meaning of love, the sexes, death, and the Christian hope of resurrection, meditating on the Wisdom of God in the creation. This work completes the word picture of divinized and Sophianic creation begun in The Burning Bush and The Friend of the Bridegroom, which together constitute what scholars call Bulgakov's -major, - or first, trilogy.
