In response to the Lutheran Formula of Concord, representatives of Reformed churches commissioned Girolamo Zanchi to draft a confession of faith acceptable to all Reformed churches. Zanchi patterned his Confession of the Christian Religion after the Apostles’ Creed, giving it a broadly Trinitarian and redemptive-historical structure that emphasizes God’s saving work for His people in His incarnate Son. It is a synthesis of his exegetical, doctrinal, and pastoral interests and stands out among his numerous publications as a useful and accessible overview of the entire Reformed theological system of doctrine. Although the project never attained confessional status at the ecclesiastical level as was planned, Zanchi’s Confession proved influential in both the Reformed theological tradition generally and the development of Reformed dogmatics in particular.
