Abstract

Christian theology is one of the most neglected areas of Leibniz’s thought. It is a subject that engaged his attention throughout his intellectual career. He seems to have been very well informed about the main currents of theological opinion in his own time, and to have had an extensive knowledge of historic doctrinal positions. He left behind a wealth of letters and unpublished papers discussing topics in revealed theology; but this resource for understanding both his own thought and the history of theology at the dawn of the Enlightenment remains largely unmined. The Academy edition of Leibniz’s works includes as yet no systematic project for the publication of his theological papers—the largest class of his papers—although important treatments of theological subjects are finding their way into series I and VI. Gaston Grua surveyed and assembled a large quantity of theological texts, but these are organized around Grua’s interest in Leibniz’s theodicy, so that Leibniz’s views on topics such as grace, predestination, and theological method are represented much more richly than other topics in revealed theology. Another topic much discussed in the secondary literature is Leibniz’s treatment of eucharistic theology, which has attracted attention because it is involved both in his negotiations about reunion of the churches and in some of his major discussions of issues about corporeal substance. But other central topics of Christian theology have received much less attention in the secondary literature; and this is true in particular of the doctrines of the Trinity and the Incarnation, even though they are rich in metaphysical resonance and Leibniz had quite a lot to say about them.
