ABSTRACT This article takes up questions regarding the interrelation of the given and the undetermined in Augustine’s understanding of the self. As a critical point, it argues that debate regarding the Augustinian self has been marked by an emphasis on given structures that has constricted conceptions of human becoming. This emphasis emerges by way of competing narratives of discovery: Augustine is presented as a discoverer either of a constitutive space of the self, or of a determinative temporality. It results in (...) accounts of formation that occlude the spiritual significance of the full sweep of Christ’s history, from incarnation through ascension. As a constructive point, this article argues that Augustine positions himself to develop a Christological vision of Christian becoming, rooted in attention to all aspects of Christ’s life and work, by understanding space and time not as structures that fix the bounds of human becoming, but rather as realities that take on different forms in accordance with differing modes of love.
