Leibniz saw the question of the eucharist as a crucial stumbling block to the agreement between Lutherans and Calvinists. Mandated together with Daniel Ernst Jablonsky to prepare working documents for the negotiations between Hanover and Brandenburg in 1697, Leibniz carefully read through the Calvinist Confessions of faith and the works of Calvin in their 1671 edition. He made an extensive collection of excerpts from the Confessions of faith and from Calvin's Institutes all intended to show that Calvinists admitted the substantial presence of Christ's body in the eucharist. (This collection of excerpts is analysed here for the first time and compared with another little-known document, the Unvorgreiffliches Bedencken). L. had argued previously in 1691/92 that, contrary to the assertions of Pellisson-Fontanier, his own conception of substance and of Christ's presence in the eucharist was completely different from Calvin's. However, by 1697, it was clear to Leibniz that Calvin's concept of substance, which was broadly speaking Aristotelian, was never defined clearly by the reformer, and could be made to coincide with Leibniz's own notion of substance as force rather than substance in its dimensional sense. At the same time L. dissociated Ubiquitarianism (doctrine characteristic of late sixteenth century Lutheranism, which defended the dimensional presence of Christ's body in heaven and in the eucharist, by arguing that Christ in his divine nature could cause his physical body to be present in several places at the same time) from Lutheranism. He also drove a wedge between the doctrines of Zwingli and Calvin. L. thus attempted to find religious union on a common ontology and he might well have succeeded if it were not for complex political circumstances, which ultimately caused the failure of the negotiations

Seule la traduction et l'édition grecque simultanée de 1575 est dépourvue d'intention doctrinale ou polémique; le problème de la paternité de cette traduction pose un problème, Hopper étant mort en 1564. .

This essay investigates how Leibniz and Daniel Ernst Jablonski handled the ironing out of intra-protestant religious differences, notably on predestination in the years ca. 1697-1702. I shall be focusing on the recently published union document between the Lutherans of Hanover and the Calvinists of Brandenburg, entitled the Unvorgreiffliches Bedencken (hereafter UB) and on the equally recently published and hitherto practically unknown Meditationes pacatae de praedestinatione et gratia, fato et libero arbitrio of 1701-ca. 1706 2. This is a series of Leibniz’s annotations on Jablonski’s Latin translation of article 17 (predestination) of the bishop of Salisbury, Gilbert Burnet’s Exposition of the 39 Articles of the Church of England. I shall try to show how the issue of predestination is handled in the UB by Leibniz and how his notes on the Meditationes complement and modify Jablonski’s Latin edition of the 17th article of Burnet’s Exposition the Thirty-Nine Articles of the Church of England. This will enable us to isolate the set of theological problems faced by the Lutheran and Calvinist participants in the negotium irenicum of 1697 -1702 and to point to the specific nature of the solutions proposed by Leibniz which were philosophical rather than theological. The underlying issue here is that of coexistence of philosophy and theology in Leibniz’s system. Indeed, one of the persistent questions about this philosopher concerns the exact relationship between his metaphysics (including physics and mathematics) and his theological views: which determined which? I hope to take the debate further here by analysing Leibniz’s contribution to the specifically theological issue of predestination, which, it will emerge, has direct bearing on Leibniz’s Essais de théodicée of 1710.
