This chapter discusses Leibniz’s views on key Christian doctrines that were surrounded, in the early modern period, by particularly lively debates. The first section delves into his defence of the Trinity and the Incarnation against the charge of contradiction, and his exploration of metaphysical models capacious enough to accommodate these mysteries. The second section focuses on the resurrection and the Eucharist, with special regard to their connections with Leibniz’s metaphysics of bodies. The third section investigates Leibniz’s position on predestination, grace, salvation, and damnation. It comes to the conclusion that salvation, for Leibniz, does not ultimately depend on believing a set of true doctrines, but on a practical attitude: the love of God above all things. Leibniz’s theology is thus fundamentally a theology of love that is ultimately practical and tries to be both universalist and Christian.
