Seminarians' existential crises of faith are often-experienced but little-studied. Through surveys of Millennial MDiv students (n = 30) and seminary Student Affairs and Student Services Professionals (SASSPs) (n = 44), this study suggests crises of faith are fundamental to MDiv students' spiritual formation, mirroring the pattern of Mezirow's Transformative Learning Theory model (TLT). TLT also undergirds secular Student Affairs, where SASSPs regularly provide co-curricular "student learning" support. This study recommends training seminary SASSPs to be similarly-utilized within theological education, which would require resources for professional development from both their institutions and the Association of Theological Schools. Implications for multi-cultural theological education are also discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
