What principle did John Wycliffe emphasize in his teaching?

John Wycliffe emphasized Scripture as the supreme authority over tradition, which was a foundational principle of his teaching. He believed that the Bible should be the primary source of authority for Christian faith and practice, and he challenged the prevailing view that church tradition and the papacy held ultimate authority. Wycliffe argued that all believers should have direct access to the Scriptures, which led him to advocate for the translation of the Bible into the vernacular, making it accessible to the common people. This idea significantly influenced later reformers and highlighted the importance of individual interpretation of Scripture.

In contrast, the other choices do not reflect Wycliffe's views. He did not endorse the papacy as the ultimate authority, emphasize monastic life, nor support the idea that indulgences played a key role in salvation. His stance on Scripture challenged the established norms of his time, contributing to the wider Reformation movement.
