RELIGION AND THE CONDUCT OF WAR, C.300-1215

By David Steward Bachrach

Book Description

Throughout nearly a millennium of Western history, the relationship between faith and warfare underwent a profound transformation that continues to shape our understanding of spirituality and conflict today. This scholarly exploration examines how Christianity evolved from its pacifist origins into a faith that not only justified but eventually sanctified violence in service of religious causes.

David Steward Bachrach traces this remarkable spiritual journey from Constantine's rise in the early fourth century through the dawn of the thirteenth century, revealing how military necessities fundamentally altered Christian practice and doctrine. The study demonstrates how religious rituals became essential to maintaining discipline and morale among soldiers, while warfare itself influenced the development of core Christian practices including prayer, communion, confession, and penance.

For those seeking to understand how spiritual beliefs adapt under pressure and how institutions reconcile seemingly contradictory values, this work offers valuable insights. The book illuminates the complex ways religious communities navigate moral challenges when faced with existential threats, showing how theological positions can shift dramatically over time.

Drawing from extensive historical sources, the analysis reveals patterns in how faith communities justify actions that appear to contradict their foundational principles. This examination of Christianity's transformation from a pacifist movement to one embracing "holy war" provides a compelling case study in spiritual evolution and institutional adaptation that resonates beyond its historical context.
