Every illustration people reach for to explain the Trinity — ice, water, and steam, a three-leaf clover, even “one times one times one” — ends up breaking down somewhere. In this episode, we take on one of the most difficult and most argued-over doctrines in church history: three persons, one Godhead.
We walk through the biblical evidence, starting in the Old Testament with “let us make man in our image,” the tower of Babel, and Isaiah’s “who will go for us,” through the New Testament’s baptism of Jesus and the explicit naming of Father, Son, and Holy Spirit. We talk about why first-century Jewish believers weren’t blindsided by the doctrine of the Trinity the way we might assume, why doctrine actually matters for everyday faith, and how a misunderstanding of the Trinity helped shape a religion that’s endured for fifteen hundred years. We close by naming a few of the classic heresies — modalism, Arianism, and Oneness Pentecostalism — so you can course-correct if you’ve picked up a wrong idea along the way.
