The Three-in-One: Who Is God?

Jun 29, 2025    Dr. Kira Moolman Pettit

What does it really mean for God to be Father, Son, and Holy Spirit, three persons in one God? In this session of our “Favorite Heresies” series, we explore three major Trinitarian heresies: Adoptionism, Modalism, and Arianism, and why they matter for our faith today. We unpack how each distorts our understanding of who God is, why it’s essential to hold to the historic teaching of the Trinity, and how the Nicene Creed helps keep us grounded. Along the way, we look at everyday analogies, examine what Scripture says about God’s triune nature, and discover how knowing God as Trinity shapes our relationship with Him. Join us as we dive into the mystery of the Trinity and why it matters for your life.
