Abstract

Union with Christ was a key doctrine for second-generation Reformed theologian Girolamo Zanchi. As a Thomist, Zanchi shared similar elements with Thomas Aquinas in his understanding of salvation as participatio, but his understanding of union with Christ differed with regard to the difference between infused and imputed righteousness. Unlike Aquinas’s doctrine of infused righteousness, Zanchi argued for imputed righteousness, which was both the foundation for one’s justification in this life as well as appearing before the divine bar at the final judgment. Zanchi’s doctrine of union with Christ has the utmost significance for personal eschatology and the judgment believers undergo at the great assize, insights that are worth retrieving for a clear understanding of the relationship between justification and the final judgement.
