One of the most important thinkers on just war and pacifism describes, analyzes, and evaluates various patterns of thought and practice in Western Christian history.

"In the world but not of it"--an expression that has been interpreted in a multitude of ways. With the publication of Rod Dreher's much-debated book The Benedict Option in 2017, the question of just how the church is to exist "in but not of the world" is once again on the minds of many. To provide answers true to the context in which the Western church now finds itself, it is worth first investigating how the question has been answered in the past. In determining what to do today, it helps to understand how we got here in the first place. At the beginning of the fourth century, people were persecuted for being Christians; by the end of the fourth century, people were persecuted for not being Christians. This book is an academic investigation of how three paradigmatic theologians interpreted this so-called Constantinian shift: Eusebius of Caesarea (ca. 260-339), Augustine of Hippo (354-430), and John Howard Yoder (1927-1997). Surprising similarities between the theology of Eusebius and Yoder become apparent, and underlying theological structures of how to interpret what it looks like to be a community that follows Christ are revealed.

Any scholarship that addresses the evolution of Christian perspectives on warfare generally references this book. Although the scholarship of this work is now outdated and critiqued, Bainton's work is foundational in the area. Bainton believes that the Christian community started out pacifistic, then developed the just war doctrine, and finally adopted holy war ideals. He traces this trajectory from the Early Church up through the wars and conflicts of the 20th century (this book was written in 1960). Finally, Bainton adds his critique of current militaristic ideas (especially in regards to atomic warfare). This book is well written and written for all audiences, however, it is best to supplement this book with more recent scholarship to get current ideas on Christian perspectives on warfare.
