In this article, I uncover a point of contact between Cornelio Fabro’s philosophical theology and Søren Kierkegaard’s theological anthropology. I survey how Fabro’s metaphysical account of the human person as a created ‘synthesis’ between the infinite and finite, also invites a soteriological account of the call of Christian discipleship. My wider argument is that Fabro unearthed a structural feature in Kierkegaard’s theological approach to free creation from nothing, human subjectivity, suffering, and freedom that mapped on to Fabro’s philosophical theology of participation. In doing so, Fabro recovered the missing metaphysical and soteriological elements of Kierkegaard’s theological emphasis on the task and goal of selfhood beyond the atheistic existentialist stereotypes of God-denial, acosmic individualism, and self-annihilation. Often construed as polar opposites, I claim that Thomistic philosophy and Kierkegaard’s existential approach can be juxtaposed fruitfully as sharing an important point of departure with free creation from nothing. In short, Fabro’s creative link between Kierkegaard and Thomas Aquinas affords a unique theological development in post-Kantian approaches to the topic of existential freedom.
