Two Resources for Your High School Graduate

High school graduation is almost here. Every Christian parent wonders this. We pray that we’ve adequately prepared our high school graduate to enter into the fray of college life: intellectually, spiritually, and morally. But, in the end, we must leave their future in the hands of the only person that controls it, God himself.

A New Academic Volume on the Origins of the New Testament Canon

It goes without saying that not all academic sub-disciplines (especially in the field of biblical studies) generate the same level of scholarly interest. Some fields are more active; others less so. And it can change from generation to generation. When I was doing my work with Larry Hurtado years ago at the University of Edinburgh,...

What’s the Best Argument for the Resurrection?

Well, soon it will be Easter. That wonderful time of the year when we remember (and celebrate) the resurrection of Jesus from the dead. But, not all will be celebrating. There are many that find Easter to be a senseless holiday—apart from, perhaps, the joys of Sunday brunch or chocolate eggs. After all, it is...

About Dr.
Michael J. Kruger

Welcome to the website of Michael J. Kruger, the Samuel C. Patterson Chancellor’s Professor of New Testament and Early Christianity at Reformed Theological Seminary.

Featured Content

Sarah Eekhoff Zylstra sat down with New Testament scholar Michael J. Kruger, one of Ehrman’s former students, to talk about Ehrman’s arguments on why he doesn’t believe in God. Kruger has found that, unlike Ehrman, the study of biblical manuscripts has strengthened his faith.
When did Christians first recognize the biblical canon and how do we know we have the right books? On the Sean McDowell Show, Dr. Michael Kruger unpacks what “canon” means, why recognition began far earlier than the 4th century, and how both intrinsic factors (covenant, apostles) and extrinsic factors (heretics like Marcion) shaped the process.
Michael Kruger challenges the modern assumption that the Bible was chosen arbitrarily. With clarity and care, he explores the historical, theological, and cultural evidence that the canon wasn’t imposed, but emerged within the early Christian community.

Miniature Codices in Early Christianity

This volume is the first full-length monograph on the phenomenon of the miniature codex, offering a framework for distinguishing miniature codices from other tiny texts (e.g. amulets), exploring their practical and iconic functions, and, perhaps most importantly, assembling a detailed catalogue of all known Christian and Greek miniature codices. This distinctive book format provides an essential window into the textual, literary, and visual culture of early Christianity, shedding fresh light on how and why Christians were considered people of the book.

Surviving Religion 101: Letters to a Christian Student on Keeping the Faith in College

For many young adults, the college years are an exciting period of self discovery full of new relationships, new independence, and new experiences. Yet college can also be a time of personal testing and intense questioning― especially for Christian students confronted with various challenges to Christianity and the Bible for the first time. Drawing on years of experience as a biblical scholar, Michael Kruger addresses common objections to the Christian faith―the exclusivity of Christianity, Christian intolerance, homosexuality, hell, the problem of evil, science, miracles, and the reliability of the Bible.
