In A Systematic Theology of the Early Church , Dustin R. Smith offers a groundbreaking exploration of the foundational beliefs that defined first-century Christianity, rooted solely in the Old and New Testaments. Unlike traditional systematic theologies that blend scripture with post-biblical ecumenical creeds and denominational confessions, this work focuses exclusively on the authentic doctrines of the Early Church. With precision and clarity, Smith examines eight core theological pillars—theology, anthropology, hamartiology, christology, pneumatology, soteriology, ecclesiology, and eschatology—revealing the Early Church’s vibrant understanding of the only true God, humanity, sin, Jesus Christ, the Holy Spirit, salvation, the church, and the kingdom of God. Written to be accessible to a wide range of readers and believers, this volume offers the opportunity to rediscover the beliefs of the early Christians, inspiring a biblically grounded spirituality marked by faithfulness to Jesus Christ and his apostles. Dustin R. Smith, Ph.D , is a New Testament scholar at Spartanburg Methodist College. He is the author or editor of nine books, including Wisdom Christology in the Gospel of John , The Son of God: Three Views of the Identity of Jesus , and Paradoxical Conquering in the Apocalypse of John. He has served on the editorial boards of A Journal from the Radical Reformation and the Journal of Biblical Unitarianism. Dustin Smith is the weekly host of The Biblical Unitarian Podcast. " This Systematic Theology volume has been an excellent and honest read, taking great pains to evaluate the early beliefs of the first-century Church, without the unnecessary interpretations and additions of later church councils and creeds. In addition to being theologically accurate, it is also extremely practical, a quality often lacking in many works of systematic theology. As a pastor, I have found it difficult to introduce the average layperson to deeper theological works, as many other works fail to communicate the application of such findings with regular day-to-day life: this volume has succeeded in addressing that 'gap' between the scholar and the layperson. You simply will not find a more theologically honest, accurate, and applicable systematic theology than this present volume ." Talon Paul Senior Pastor, Maple Grove Community Church " Dustin Smith has produced a methodical work of reconstructing first-century theology by uncovering the beliefs and practices of some of the earliest Christians. This book serves both the serious scholar and the everyday Christian who wants to go deeper into biblical studies. Smith consistently provides daily and practical application drawn directly from the theology itself. It encourages us to live out the command from James to "be doers of the word, and not hearers only" (James 1:22). Correct doctrine leads to correct living, and the subjects in this book are treated with care and depth. If you've ever had questions about the nature of God, how sin affects human beings, what happens when we die, or how we are called to live within the church, you'll find thoughtful, biblically grounded responses to these crucial doctrines, and more ." Nathan Massie Associate Pastor, Oregon Church of God " Dustin Smith, together with his co-authors and editors, has delivered a systematic theology that is both richly biblical and refreshingly clear. This volume combines theological depth with an accessible format, offering practical wisdom for today's believer. For anyone seeking a well-organized resource that presents key doctrines from a first-century, restorationist perspective, this work is a must-have. This book is an incredible gift to the church. Clear, well-sourced, and deeply instructive, it is a resource the Body of Christ will treasure for years to come ." William Barlow Head Pastor, Compass Christian Church " Dustin Smith is to be commended for his prodigious work on Systematic Theology. He has produced a volume that surveys many of the cardinal doctrines of theology in an orderly and detailed way. His helpful introductions will serve students of the Bible to get the lay of the theological land. Though there are drawbacks to this approach, the advantage is that Smith has produced in one text a comprehensive articulation that allows the reader to observe connections between doctrines and contemplate the system as a whole ." Sean Finnegan President, Living Hope International Ministries " I've read systematic theology books before, but I've never encountered anything like this... until now! Dustin Smith endeavors to take us back to the foundations of Christianity and the early church as he explores what Jesus' original disciples believed and why, way before flawed councils and erroneous creeds that punished dissenters got involved Dustin will take you on an exciting journey with rich Jewish context and a comprehensive background to paint a beautiful picture of a deeply
