Theologians have recently shown interest in the work of Irish metaphysician William Desmond. A prevailing antimetaphysical sentiment may, however, discourage others from engaging his work. To allay concerns, this article brings Desmond into conversation with Jean-Luc Marion on the topic of divine revelation. The purpose is twofold. First, for those wary of metaphysics, this essay demonstrates that Desmond's metaxology evades Marion's critique and, more importantly, shows how the two thinkers share a “familial intimacy.” Despite the opposition between metaphysics and phenomenology, this intimacy renders them companion thinkers. Second, this companionship is theologically beneficial to Desmond. With Marion as guide, we consider how the concept of divine charity can be added into Desmond's metaphysics in what I call the passio caritatis, or “passion of charity.” The article concludes by suggesting how undergoing the passio caritatis effects a theological expansion of Desmond's metaphysics and puts it at the service of theological reflection.
