Emerging as a defining document of Reformed theology, The Second Helvetic Confession offers a comprehensive articulation of Protestant beliefs in the wake of the Reformation. Written by Heinrich Bullinger in 1562 and gaining widespread adoption shortly after, it addressed the perceived limitations of its predecessor and distanced itself from Lutheran formulations. Embraced by Reformed churches across Switzerland, Scotland, Hungary, France, and Poland, the confession became one of the most authoritative expressions of Reformed doctrine alongside the Heidelberg Catechism. It explores central theological themes such as the nature of Scripture, the sacraments, ecclesiology, and Christology with clarity and conviction. Rooted firmly in its 16th-century context, this confession captures the intellectual and spiritual rigor that shaped a significant branch of Protestantism. A cornerstone of Reformed identity, it continues to illuminate the foundational principles that defined a critical era in church history.
