In this book, I have suggested that we best understand Calvin's Christological thinking if we pursue it under the rubric of Christ as Mediator, the rubric that Calvin himself repeatedly offers. Moreover, I have argued that we go to the heart of this Christology when we locate Christ's mediation within the context of the covenant history, even as Calvin does in his introduction to Christology in the Institutes (II.vi). This has allowed me to explicate Calvin's Christology expansively, under the threefold office of priest, prophet, and king, and to situate Calvin's understanding of Christ's person in relation to his office.

What, finally, can I say about the character of Calvin's Christology on this basis, and what might such a Christology contribute to contemporary Christological thinking? A first characteristic of Calvin's Christology is its eclecticism – that it embraces a variety of biblical themes and addresses a multitude of existential situations in the breadth of its exposition. But this eclecticism does not leave us with a doctrine that is scattered and unfocused. Rather, the approach that I have taken suggests that the rich diversity in Calvin's thinking emerges from and revolves around a Christology that is historical and relational in character. That is what it means to locate Christology in Christ's office as Mediator of the covenant. Lest this seem like a trivial observation, let me expand on the significance of these additional characteristics, turning first to Calvin's concern for history and then to his attention to relationality.
