Heinrich Bullinger (theologian)

Heinrich Bullinger (1504–1575) was a Swiss Protestant theologian and church leader, succeeding Ulrich Zwingli as the main figure in Zurich’s Reformation. He helped shape Protestant beliefs and church practices during a crucial period of religious change, emphasizing the authority of Scripture, the importance of faith, and the central role of Christ. Bullinger also promoted unity among Protestants and engaged in important theological debates of his time. His work influenced later Reformation movements, and he was a key defender of Protestant principles in the face of Catholic opposition.
