The document explores the Protestant doctrine of 'sola scriptura,' emphasizing that Scripture alone is the ultimate authority for Christians, surpassing church traditions and papal decrees. Key reformers, including Martin Luther and John Calvin, argued that individual interpretation must align with Scripture and warned against reliance on non-biblical teachings. The document contrasts this with the Catholic Church's perspective established at the Council of Trent, which holds both Scripture and tradition as authoritative, asserting that the church retains the final interpretive authority.
