Gavin D'Costa's writings represent a significant attempt in the current discussion of the theology of religions to utilize the resources of Trinitarian doctrine and address the function of religions in the divine salvific plan. This paper systematically outlines his theology through an interpretive model of particularity/universality to elucidate its structure and highlight his emphases on Christology, Pneumatology and Ecclesiology. I argue that while his system has the considerable merit of a desire to maintain a single economy, there remain several difficulties, including a possible conflation of salvific will and grace, and a dissonance of the proposal of limbo with his system.
