Mystical theology is better understood as a "wisdom of experience" than a "wisdom of doctrine." It arises from bringing mystical experience into words, though such experience cannot be captured in doctrinal propositions. Consequently, mystical theology always describes the way, journey, or transition toward an ineffable experience of God. While its doctrinal content has often seemed unimpressive, tracing its historical roots—such as Augustinian, Neoplatonic, or gnostic motifs—misses the path of mystical theologians. To share in their experience, one should join them on their journey, for example with Bernard of Clairvaux on the "ladder of love" or Bonaventura on the "pilgrimage of the soul to God."
This paper examines Hans Boersma's critique of Bonaventure's view of the beatific vision. Boersma argues that mystical union with God in this life must involve both intellect and will, contrary to Bonaventure's claim that it occurs only through the will. The author contends that Boersma overlooks Bonaventure's Commentary on the Gospel of John, where Bonaventure explains that the beatific vision does unify intellect and will, but sin prevents the intellect from experiencing such union in earthly life. The analysis suggests Boersma requires a more robust account of intellect and will to effectively critique Bonaventure.
