The word “Trinity” never appears in the Bible… so why do Christians believe it?

In this episode of Ask Dr. E, Michael Easley answers a thoughtful question about the Trinity, early church history, and whether Christians should describe God more “mysteriously” rather than as three persons in one God. Dr. Easley explains why the doctrine of the Trinity matters, why common analogies often fail, and how Scripture consistently reveals the Father, Son, and Holy Spirit working together as one God.

Using passages like Matthew 3 and 1 Corinthians 12, this conversation explores how the Trinity is taught throughout the Bible even if the specific word itself is not used. Dr. Easley also explains why rejecting the Trinity leads to major theological problems—including modalism and polytheism—and why the doctrine is essential to understanding salvation itself.

If you’ve ever struggled to explain the Trinity, questioned whether it’s biblical, or wanted a clearer understanding of the Father, Son, and Holy Spirit, this episode will help ground you in Scripture and strengthen your confidence in Christian doctrine.
