This is an overview of Christian apologetics, from its beginning in the New Testament through the Middle Ages and on to the present resurgence of apologetics among Catholics and Protestants. Dulles shows how Christian apologists have at times both criticized and drawn from their intellectual surroundings, to present the reasonableness of Christian belief. Written by one of American Catholicism's leading theologians, "A History of Apologetics" also examines apologetics in the 20th and early 21st centuries including its decline among Catholics following Vatican II and its recent revival, as well as the contributions of contemporary Evangelical Protestant apologists. Dulles also considers the growing Catholic-Protestant convergence in apologetics. It is of interest to students of apologetics and contemporary theology.
