“Christian faith has a dramatic conception of man. A person is not a thing with attributes; a person is a story. It is for this reason that I suggest that personal identity be understood as the dramatic continuity of a story” (Jenson, Knowledge, p. 151).
In his Thinking the Human, Jenson clarifies that logic somewhat: treating a person as a static essence differentiated by accidents, while commonsensical, does not take seriously enough our sheer contingency as creatures, the startling fact that we are, in an ontological sense, accidents all the way down. That I perdure as an unity in time is only ever due to God’s continuing to speak me into being (so, we must also reject any conceptual distinction between “creating” and “sustaining”): my existence is the story God is telling about me.
