Why do you believe what you believe? Understanding Epistemological Presuppositions

Why do you believe what you believe?

On this episode of The Capitol Ministries Weekend, Ralph Drollinger unpacks the vital role of epistemological presuppositions—our foundational beliefs about truth and knowledge—and how they shape decisions, worldviews, and policies.

🎙️ Joined by Frank Sontag, Ralph challenges both believers and skeptics to ask:

➡️ What is your source of truth?
➡️ Are your moral assumptions based on Scripture, culture, or self?
➡️ How do your presuppositions influence your leadership and vote?

Drawing from 2 Corinthians 10:5, Ephesians 4, and Romans 1, this conversation explores how God’s Word stands as the only authoritative and unchanging source of truth in a fallen world.
