A Brief History of the Doctrine of the Trinity narrates the formation of this crucial concept in a concise and illuminating manner. Using the writings of the Church fathers as a starting point Dunzl presents the story afresh in a way that even those closely familiar with the field will find engaging and innovative. The disputes over the theology of the Trinity are vividly evoked, pointing out the foundations of the doctrine and the decisive shifts in its development. The often bitter discussion surrounding this development is seen not as a barren dispute but as an evolutionary process in which rivalry is a necessary and positive factor in furthering the debate.
