How do we know evangelical principles are true?

The truth of evangelical principles is established through their strong foundation in Scripture, the historical teachings found in the Church's articles, and the writings of significant theologians throughout history. For instance, the Thirty-Nine Articles of the Church of England reflect key aspects of evangelical doctrine, asserting the necessity of Scripture alone for salvation. Moreover, a thorough examination of evangelical leaders from the Reformation to contemporary times reveals a consistent commitment to biblical fidelity and the core tenets of Christianity as contained in the Scriptures.
