ABSTRACTThis contribution investigates the mystical anthropology of two important and related medieval mystics, William of Saint-Thierry and Hadewijch, neither of whom were well known in their own day, but who have come to the fore of scholarly attention in recent years. In the first part, the authors explore the Trinitarian theology of William of Saint-Thierry and the ways in which it provides the foundation for his mystical anthropology. William radically argues that the human soul is structured according to the pattern (...) of the Trinitarian life, and advocates a reciprocal and mutual encounter between the soul and God in which each touch and pass over into one another, becoming one Spirit. In the 13th century, Hadewijch would draw on William’s fundamental insights, integrating them into her own mystical-theological thought. Following her theoretical reflections on the nature of the soul, and unlike her contemporaries in the Schools, Hadewijch maintains that the soul has the natural potential to be united with God without a created intermediary, and that in mystical union, the soul becomes God in love.
