This thesis examines questions of humanity and divinity that are pressing in contemporary philosophy and theology as seen in the thought of Dietrich Bonhoeffer and Richard Kearney. Both these thinkers seek to address issues around transcendence/immanence, sameness/difference, ontology/ethics, and post-metaphysical approaches to God. Chapter one explores the many convergences in their thinking with regards to these topics. Chapter two looks at the main divergence in their thinking: their respective Christologies. Chapter three, following up on the exploration of convergences and divergences in their thought, examines a possible way in which to mediate the difference in their otherwise similar patterns of thinking. The thesis aims, overall, to show that a Christologically-based incarnational humanism is a suitable and appropriate live option that is not only biblical, but also responds to issues in both contemporary philosophy and theology, providing a way to understand how the possibility of divine incarnation depends upon our ongoing human response.
