There is a lot of talk about heresy these days. The frequency and volume of accusations suggest that some Christians have lost a sense of the gravity of the word. On the other hand, many believers have little to no familiarity with orthodox doctrine or the historic distortions of it. What's needed is a strong dose of humility and restraint, and also a clear and informed definition of orthodoxy and heresy. Know the Heretics provides an accessible 'travel guide' to the most significant heresies throughout Christian history.
As a part of the KNOW series, it is designed for personal study or classroom use, but also for small groups and Sunday schools wanting to more deeply understand the foundations of the faith. Each chapter covers a key statement of faith and includes a discussion of its historical context; a simple explanation of the unorthodox teaching, the orthodox response and a key defender; reflections of contemporary relevance; and discussion questions.

Excellent book! Introduces major heretics from church history and explains the false teachings they put forth, then gives the response of the orthodox church at the time. Each chapter concludes with a few questions, which would make this great for a group study.
This book is not an exhaustive listing of all of the heresies out there, it is a sampling of the more major ones, with an explanation of the heresy, the history and the main person behind it, the orthodoxy response, the importance of the heresy and the response today and a list for further reading after each section.
The book was laid out in a very reader-friendly way. Religious non-fiction can be dry, lengthy and boring. This book managed to easily dodge each of those pitfalls.
This was going to be a 4.5 star book, rounded down, BUT I realized that it earned a full five stars because it not only caused me to learn something, it ALSO led me down the rabbit hole of "I don't know anything about this thing, now I need to learn about it!". So now I'm going to try to find out more about Original Sin. It's not something that was focused on much when I was in Sunday School (not Catholic, so all I know is it's cause Adam and Eve fell by disobeying God. Maybe that's all it is, but I don't know.) Original Sin is a subject that was one of the contentions in a heresy and was the only heresy that I didn't fully understand the issue at hand. So something requiring more study by me to be sure.
So this book gave me what I was looking for, I learned more about something I didn't know that much about and it led me to further study.
My thanks to NetGalley and Zondervan Academic for an eARC copy of this book to read and review.
"All I need is my Bible as my guide - I don't need any formal instruction or knowledge of 'how it was done before'…"
I have heard this quite a few times from people, and I used to giggle at it not really understanding how little I knew about the church. My exposure to info in church until fairly recently was limited to the small window of insights from the independent baptist church I grew up in. Why do we affirm a Triune God (and what are the possible nuances in that)? Was Christ both fully human and fully divine? Was He…real like us? What did He die for?
Sure you could say all you need is the Bible to those questions and my prayer is that the Holy Spirit would guide you to orthodoxy in His sovereign will, but…there's absolutely something to be said for at least a basic understanding of how orthodoxy developed over time.
We - the church - didn't arrive at our positions on things until they were challenged. Heresies often carry the name of the person who championed them (there are exceptions, though). Understanding the why behind what they were trying to do will only help one in preventing themselves from falling suspect to the same tricks.
This book goes into enough detail to explain some general reasons why various heresies came to be, and what the church catholic did in response. There's politics, charismatic personalities, different nuances in approach that are all relevant to the situations, and this book does well in highlighting what's relevant, explaining in enough detail that things can be pretty easily understood, all while not getting too far into the weeds. Even better, the organization is such that there is a certain level of continuity - there's a bit of association between heresies over the years, and the order they're put in naturally points a bit of that out. The "contemporary relevance" sections do well in modernizing what those heresies were…and I'll definitely be following up with a few of the suggested readings at the end of the sections.
I'm interested in more of this "Know" series now…good job, Mr. Holcomb.
offers an informative and in-depth overview of key heresies that have challenged Christian doctrine throughout history. It provides a clear explanation of heterodoxy, helping readers understand why theological accuracy matters. One of the book’s strongest insights is the idea that truly loving God requires seeking to know Him rightly. The structured approach—walking through different heresies in a simple, predictable format—makes the content accessible and easy to follow.
However, while the book is undeniably important for faith formation, it’s not the most engaging read. The writing is clear but not particularly gripping, making it more of a reference book than a page-turner. Given its value for understanding Christian doctrine, it’s worth reading, but it wouldn’t be at the top of my recommendation list.
A fantastic read that overviews many of the prominent heresies, especially from the patristic age. The heresies covered in this book: Judaizers, Gnostics, Marcion, Docetists, Mani, Sabellius, Arius, Apollinarius, Pelagius, Eutyches, Nestorius, Socinus.
Each chapter deals with a different heresy and includes the historical background, an overview of their teaching, the orthodox response to the heresy, and the contemporary relevance.
If you're interested in learning about church history, theology, and/or doctrinal discernment, give this book a read.
I read it for my Historical Theology class at Moody Bible Institute.
A helpful primer on heretics and heresies in the early church with a focus on Nicene Orthodoxy, that is, a biblical understanding of the Triune God. Each chapter includes historical background, heretical teaching, orthodox response, and contemporary relevance. The last section was particularly useful as it demonstrates where the heretical ideas remain alive and well today. The author’s conclusion was also helpful as he exhorted believers not to label every doctrinal disagreement “heresy” but to reserve that language for errors that depart from Nicene Orthodoxy. Quite a useful little book.
This is a great book to better understand how the heresies of the past caused Christians to develop sound biblical theology. It also is eye opening to see how these heresies in different forms are creeping into the church today. The author gives a relevance to the church today at the end of each chapter. We need to keep in mind the struggle for Orthodox teaching and encourage one another to be guardians of the Gospel!
Even heretics are helpful conversation partners when it comes to theology. That was my big picture takeaway from this. It's helpful to hear the stories of men who have fallen into ditches, what they were, how they got there, in order to learn from their mistakes, to engage their theology with Scripture, and to reform our own.
Another takeaway: there is nothing new under the sun. Wrong beliefs seem manifold, but they really are all just many shades (I will not say fifty shades) of grey. History, even church history, helps to supply us with something of a genealogy of belief, and an understanding of how things got to be where they are.
It's also nice that this was one of the briefest books I've read this year. I recommend it, if you are able to supplement your reading with something small.
Great concise resource on this topic. Covers the major heresies through church history, while helpfully showing how they are still present in our modern context.
While I appreciated all the historical information on church controversies, my favorite parts were the introduction and conclusion in which the biblical treatment of those we disagree with was addressed.
"Unlike some churches today, the early church did not stipulate all of the minor beliefs that its members should hold, nor did it consider mere disagreement to be heresy."
"We must remember that the entirety of what we think Christians SHOULD believe is not identical to what a person MUST believe to be saved. We believe in justification by faith in Christ, not justification by accuracy of doctrine."
"We can still say that their teachings are not a good application of Scripture to life and doctrine. But don't treat them as heretics. Treat them as brothers and sisters with whom we lovingly disagree."
While it may not be as rare as generation or two ago, reading a Episcopal Protestant with reform leanings writing on Patristic Christology is quite interesting. This perspective enables one to see the Protestant relationship to the "credal" early church. This book focuses on 12 heresies as way of explaining the Orthodox point of view--from a reformed perspective. Holcomb uses both Catholic and Eastern Orthodox explications of the Patristic writings in his works cited, so his view, while definitely reformed, seems very much ecumenical in spirit. Most of the 12 heresies are either ante-nicene or the Christological heresies which concerned the first four ecumenical councils. The exception is the chapter on Socinus, all of these are heresies of the early church.
Holcomb's reformed Episcopal theological leanings are clearest when he writes about the Judaizers. Another point where the Protestant leanings are clear is Holcomb's not mentioning that both Tertullian and Origen, while key church fathers, were both anathematized. Tertullian himself succumbed to the Montanism heresy, which while not a Christological dispute, did have serious implications for proto-Catholic/Orthodox views of forgiveness. Origen was anathematized after his universalism, and his accidental but historical connection to Arianism (whhich Holcomb does actually admit). Finally, using Socinus as a major history is indicative of a relationship to the reformed tradition. While Polish and Transylvanian Unitarianism does lead to modern Unitarianism and Unitarian-Universalism, it is a minor moment in Christian history whose main ideas can be found in other heretical movements. It, however, is particularly significant in Reformed history.
Another issue with the book is that a small chapter on Gnosticism may be over-ambitious. Gnosticism being such a huge category, and one where there are significant disagreements in both historical and even orthodox Christian circles as to what technically belongs to the category. The various issues with Gnosticism are hard to pin down in such a short chapter. Gnostic tendencies to re-emerge in late antiquity and in the medieval period add to the protean nature of the category.
Still, despite these criticisms, I find this book to be honest about what the Orthodox point of view from the perspective of the credal churches--most Protestant, Catholic, and Eastern Orthodox--actually state they believe. In any age of religious illiteracy in general, this sort of education perspective is important even if one is not only not reformed, but perhaps not even a Christian. It packs a fair amount of analysis and history in under 200 pages, and, for that alone, I give it a high recommendation.
Last year I started to read about church history, from the Apostles in the book of Acts to the Protestant Reformation. Among Roman emperors, church theology and famous theologians I read a few stuff about heresies in the church so when I saw this book I knew I had to read it.
Know the Heretics its a great book because of mainly two things:
First, Holcomb did a great job reuniting in a small and accessible volume the main heresies of church history. You will find some that may be known to you like the old teachings of the Judaizers. But there are also other beliefs that were held by other religious figures like Mani, who believed he was the promised Paraclete. Or those who followed the Docetism movement, and believed Jesus was fully divine while he was on earth and his physical being was just an appearance.
Being a short book, each chapter presents a single heretic and it’s divided presenting its historical background, the heretical teaching, the orthodox response and the contemporary relevance.
And second, one of the conclusions I came up after reading and learning some church history is that you get to value and to understand something even more when you get identified with its past. Knowing more about church as the body of Christ and even knowing about the heresies in its past will make you be grateful with God and with those who fought for what was right. This book does an excellent at not only describing and giving you historical facts, but also telling you the importance for you to know such information.
I recommend this book not only for those looking to learn a good lesson about history but also to those willing to stand for what is right by getting to know the heroes of our past.
Rating: ★★★★★
I received this book for free from the Booklook Bloggers program for this review. I was not required to write a positive review. The opinions I have expressed are my own.
Book Review: Know the Heretics by Justin Holcomb - a short look at beliefs of the historic heretical movements. Two points that I think are very helpful from the book: 1) Hersey usually started trying to simplify or 'fix' confusing doctrines. 2) Flippant use of the word heresy can ruin the actual meaning to the point of making the concept useless. Kindle book is only $3.79 right now. There is also a companion book, Know the Creeds that I have picked up and will probably read fairly soon. I do think this would be a good book for a small group discussion, there are discussion questions and the chapters (and whole book) are short enough to make it easy to read and discuss.
Zondervan sent me a copy of "Know the Heretics" by Justin S. Holcomb in exchange for an honest review.
This book is the natural successor to a book I've already reviewed, "Know the Creeds and Councils" by the same author. Much of what I said of the basic format of that book also applies here, so I won't give attention to the external features. Rather's I'll give attention to the difference between this book and that.
The concern of this book is primarily to help us appreciate the weight behind the word "heretic." In modern discourse, that word is used much too flippantly. To aid in this, Holcomb explores twelve major heresies that were significant in the early church. Each chapter generally has three sections: 1) what did the heretic teach? 2) how did the orthodox respond? and 3) how is this heresy relevant today? Holcomb covers all three in a commendably clear and concise manner.
As with "Know the Creeds and Councils," I heartily recommend this book, especially for learning basic church history and doing a Sunday School or book study on church history. Be sure to check it out!
Brief overview of 12 different heresies throughout church history. Holcomb does an admirable job of concisely discussing historical context, theological significance, and applying the error to today. He makes it very accessible. He tells the stories well, and highlights the key biblical issues clearly. For a book focused on recording and warning against heretical beliefs, it is actually quite positive in tone.
At some points the history feels a little reductionist, but much better than often happens in books written to be clear accessible discussions of historical events. At times, the way he discusses issues related to divine immutability/impassibility sound strange. Not sure if he was trying to avoid the issue in such a brief book, or if he disagrees with patristic views on the matter.
Early in our marriage, Ben and I read a chapter of this book together every night. I picked it up again because I have found myself engaging with people who are concerned about “purity” of our denomination. My thought is that our focus should be on orthodoxy. And a denomination needs less protection than the people—bodies and souls— that make it up. I think a poor view of our bodies and an inflated view of a denomination is the result of a small view of Jesus. Which is often heretical.
Holcomb is articulate in explaining the history of, responses to, and reactions to heresy. It is concise, though not comprehensive. Each chapter examines a different heresy. This little book is digestible for a layperson like me.
Fantastic little book on major heretical teachings in church history. Too many Christians are woefully ignorant concerning the theological errors that have plagued the church since the ascension of Christ. Sadly, we are poorly equipped to resist reincarnations of heretical teaching today, largely because we’re so ignorant of the past. This little book is an easy-to-read, short, clear work that goes a long way to help remind us where we’ve been. I could see this book (and some of the other works in this series) being helpfully turned into a Sunday School course on church history. Highly recommend this one.
I have read thousands of pages and multiple books on Church History. Most of them give a very lengthy and robust depiction on the heroes and heretics of church history. One of the major issues with those works is that they can reduce or simplify their works to give to the everyday Christian. To allow them to understand the history, its impact, and its relevance today. Holcomb's book "Know the Heretics" does that. After reading this, I want to hand this book (and the others in the KNOW Series Books) to the everyday church member so they can understand how God has walked with his bride through the ups and downs of her history.
This is an excellent guide to 12 major heresies, with chapters carefully organized for context, wrong teaching, orthodox response, and contemporary relevance. The writing's clear and concise, and the organization makes it usable as a quick reference.
Minor aside: the chapters on Eutyches and Nestorious could have been switched in order for a little clarity, and some of the Eutyches chapter could have used better explanations, but only a little.
This one's definitely worth a read to anyone who's at all interested.
Concise overviews that are yet of sufficient depth and scope as to be beneficial. Know the Heretics runs through a number of the Christian church's most important heresies while neither neglecting the socio-historical context nor becoming encumbered with overly technical theological language. A beneficial resource for both the Christian home and the pastor's office.
Good short book that discusses the major doctrinal disagreements down through history and how they helped to define orthodoxy. Defines what heresy is and gives warnings on labeling every disagreement a heresy. Showed what the orthodox response was to each heresy and its relevance for today.
Good, concise overviews of some of the most well-known heretics from early church history. Each brief chapter includes some historical context, the heresy itself, the orthodox response, notes on any contemporary relevance, a few questions for further thought, and a handful of key bibliographic resources. A good resource for any student of biblical truth.
Great book that is super enlightening and fascinating and made me think about nuances about who God is in a way I had never considered before. Knowing the major heresies of the past and the clashes in church history makes you think about the subtle contours of how you describe God, Jesus, and the Holy Spirit and really demands precision of you.
Very good overview of the doctrinal issues that led the church to formulate a Biblical understanding of who Jesus is. Interestingly, the debt is owed to heresy. God indeed uses unbelievers to accomplish His ends.
Fantastic. Holcomb brilliantly summarizes the men, topics, verbiage, and historical context for anyone to engage. His writing style is helpful and vibrant. Is historical theology dry? Not with Holcomb. Great introduction on the topic of heretics. This book should be on every Christian’s shelf.
A fine contribution to the KNOW series with very readable introductions to the historic heresies that have distressed the Church, how orthodoxy responded to these heresies, and the contemporary significance of these debates.
