In the patristic and medieval periods, the trilogy of biblical books ascribed to Solomon (i.e., Proverbs, Ecclesiastes, Song of Songs) was understood to be a symbolic unity encompassing both the tripartite division of Greek philosophy and the ‘three stages’ of the soul’s mystical ascent to union with God. Reflection on these books unfolded around a series of complex interrelationships between scriptural hermeneutics, philosophical theology, ascetic practice, and mystical experience. This course explores key themes of Christian spirituality and development across the three stages: purification, illumination, and mystical union; the role of asceticism, the nature of knowledge, the structure of the world, and union with God.
