Waldensians affirm that the Bible is the authoritative Word of God and the supreme standard for doctrine and practice. The Waldensian Confession asserts the full authority of Scripture and its trustworthiness as a guide for faith and morals. However, contemporary Waldensian theology, especially since its academic theologians have engaged modern biblical scholarship, does not typically maintain a rigid doctrine of strict inerrancy.

Instead, Waldensian theology affirms that Scripture is fully authoritative and reliable in its theological and moral teachings without requiring scientific precision on all matters or denying the historical particularity and human limitations of biblical texts. Many Waldensian pastors and scholars accept the results of critical biblical scholarship (source criticism, redaction criticism, historical-critical analysis) while maintaining the authority and theological reliability of Scripture.

This nuanced position reflects the Waldensian Church's commitment to both biblical authority and intellectual honesty. The denomination encourages engaged study of Scripture that takes seriously both the claims of the text and the methods of modern scholarship, always with the aim of deeper understanding and more faithful application of biblical truth.
