A Preview of My New Book: The 10 Commandments of Progressive Christianity

I am pleased to announce my new book has just been released: The Ten Commandments of Progressive of Christianity (Cruciform Press, 2019).

As most readers will know, I did a blog series on this theme a couple of years ago. Tim Challies, who runs Cruciform Press, approached me about expanding the material into a small, introductory book, in hopes of getting the content into the hands of more people. Cruciform Press has done a good job publishing solid, accessible books by authors like John Piper, Tony Reinke, Joel Beeke, Jerry Bridges, and others.

The fact that the book was essentially released over the Christmas season is fitting, I …

The Heresy of Orthodoxy: How and When was the New Testament Canon Put Together?

For the last few weeks, I have been posting a series of videos where Andreas Köstenberger and I discuss our response to Walter Bauer’s thesis on heresy and orthodoxy in early Christianity.

These discussions are based on our book, The Heresy of Orthodoxy: How Contemporary Culture’s Fascination with Diversity Has Reshaped Our Understanding of Early Christianity (Crossway, 2010).

The first week was an overview of Bauer and why we wrote the book (see here), and the second week was on the role of diversity in the NT books themselves (see here).

In this video below, we discuss an area very central to the Bauer thesis, namely the development …

In Honor of Thomas Oden: Seven Essential Lessons Learned from an Evangelical Scholar in the Secular Academy

I just learned here that the well-known evangelical scholar Thomas Oden has passed away.  Oden was known for starting out as a classic liberal scholar and later becoming orthodox–a rare feat in today’s world.

A number of years ago, I had the joy of meeting Tom when he came to RTS Charlotte to speak at our Harold O.J. Brown Lecture series.  He was a delight.  In honor of his passing, I republish below an article I did in 2015 on his book, A Change of Heart.

I think that book (and the summary below) captures the essence of his life’s story.  And it has a number of things …

Where Are All the Heretical Bishops in the Second Century?

A number of my recent posts (e.g., see here) have been dealing with Walter Bauer’s 1934 book Orthodoxy and Heresy in Earliest Christianity which insists that Christianity was wildly diverse in the earliest centuries and that the heretics outnumbered the orthodox. It was not until the 3rd and 4th centuries, it is argued, that the orthodox began to turn the tide.

But let’s test this theory by asking a simple question: who were the bishops in second-century Christianity?  If heresy was as widespread as orthodoxy, we should expect to find a number of bishops that are openly Marcionite, Ebionite, Gnostic, and beyond.

The problem for Bauer’s thesis is that …

How Diverse Was Early Christianity? Clearing Up a Few Misconceptions

For some critical scholars, the most important fact about early Christianity was its radical theological diversity. Christians couldn’t agree on much of anything, we are told. All we have in the early centuries were a variety of Christian factions all claiming to be original and all claiming to be apostolic.

Sure, one particular group–the group we now know as “orthodox” Christianity–won those theological wars.  But why (the argument goes) should we think this group is any more valid than the groups that lost? What if another group (say the Gnostic Christians) had won?  If they had, then what we call “Christianity” would look radically different.

Thus, according to these critics, …
