What does WSC 3 primarily teach about the Scriptures?

The Westminster Shorter Catechism (WSC) Question 3 specifically addresses the authority of Scripture in revealing what humanity is to believe concerning God. It emphasizes that the primary purpose of the Bible is to communicate essential truths about God, faith, and salvation, thereby guiding individuals in their beliefs. By focusing on what man should believe about God, the WSC underscores the doctrinal content of Scriptures rather than just moral living or interpretative methods. This foundational belief highlights the importance of theology and doctrine as central to Christian faith, making it clear that the Scriptures are not merely historical texts or moral guides but a divine revelation intended to inform one's faith and understanding of God.

The other options, while they touch on aspects of biblical teaching, do not encapsulate the primary message of WSC 3. The focus on theological belief signifies that understanding God is fundamental to the Christian experience, echoing the importance of Scripture in informing one’s faith.
