In his well-known monograph, Conciliar Christology, Timothy Pawl purports to provide a model of the incarnation that coherently affirms all the declarations of the ecumenical creeds and councils. Recently, Pawl has extended his model to incorporate a version of divine simplicity as well. Unfortunately, Pawl’s accommodation results in both argumentative and metaphysical grounding problems. On the argumentative side, the revised conception of simplicity Pawl deploys undercuts many of the standard arguments offered in support of the doctrine. On the metaphysical front, Pawl’s model leaves inexplicable the capacity of the pre-incarnate Son to take on a human nature. Finally, when one combines these results with previous work by Robin Le Poidevin, a general dilemma emerges for those attempting to integrate simplicity with models of the incarnation.
