The present article seeks to further the distinctive participatory picture of Calvin through an engagement with the prelapsarian contours of his anthropology and their oft-overlooked importance for the theme of participation that is uniquely found in his thought. The interpretive argument that emerges is that Calvin’s prelapsarian understanding of participation not only necessitated mediation by Christ in a (perhaps unexpectedly) dynamic way but was also synergistic in shape (especially when considered “preceptively” as opposed to “decretively”). Calvin’s postlapsarian understanding of participation will be shown to have adaptively retained its originally dynamic mediatorial aspects through a pivotal shift towards monergism that was brought about by humanity’s fall into sin. Taken together, it will be concluded that Calvin’s prelapsarian assumptions surrounding participation not only undergirded and bolstered the monergistic postlapsarian participatory account of salvation that he is more typically known for but also provides a previously unconsidered angle deserving of conversation.
