In this accessible text, author and theologian helps you grasp the doctrine of the Trinity so we can resist attempts to distort it and articulate the Trinity in a way that's faithful to the Scriptures and impactful in our own lives.

"Simply Trinity demonstrates how much is at stake in the trinitarian debates that have recently roiled the evangelical community. I recommend it highly."--Thomas S. Kidd, professor at Baylor University; blogger at The Gospel Coalition


To truly know God, we must understand God as Trinity. But what if the Trinity we've been taught is not the Trinity of the Bible?

In this groundbreaking book, Matthew Barrett reveals a shocking discovery: we have manipulated the Trinity, re-creating the Father, Son, and Holy Spirit in our own image. With clarity and creativity, Barrett mines the Scriptures as well as the creeds and confessions of the faith to help us rediscover the beauty, simplicity, and majesty of our triune God. What we believe about the Trinity also has untold consequences for salvation and the Christian life.


"Matthew Barrett has the evangelical instinct for classic, time-tested, deeply traditional biblical teaching about the Trinity. . . . Simply Trinity proclaims the good news of the unmanipulated doctrine of the triune God."--Fred Sanders, Torrey Honors Institute, Biola University

"Readers are led away from the rocks of those who have sought to convince us that biblical, classic trinitarian theology needs radical change, and into the calm, wide sea that is the Christian community's historic faith."--Lewis Ayres, Durham University

"Matthew Barrett offers a sane and sober recovery of the church's exegesis of Scripture and defends the Christian doctrine of the Trinity against its unwitting saboteurs."--Michael F. Bird, Ridley College
