Sola Scriptura ("Scripture alone") is a foundational doctrine of Protestant theology, asserting that the Bible is the supreme and sufficient authority for Christian faith and practice. This principle emerged during the Reformation as a direct challenge to the Catholic Church's assertion that both Scripture and Sacred Tradition carry equal interpretive authority.

Core Tenets

Sola Scriptura maintains that:

• The Bible is the infallible, divinely inspired Word of God
• Scripture is self-sufficient for establishing Christian doctrine and morality
• All teachings must be tested against biblical standards
• Extra-biblical traditions, papal decrees, and ecclesiastical councils are subordinate to Scripture
