Making the case for the Christian faith—apologetics—has always been part of the Church's mission. Yet Christians sometimes have had different approaches to defending the faith, responding to the needs of their respective times and framing their arguments to address the particular issues of their day. Cardinal Avery Dulles's A History of Apologetics provides a masterful 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 Catholicism's leading American 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. No student of apologetics and contemporary theology should be without this superb and masterful work.

Laying the Foundation: A Handbook of Catholic Apologetics and Fundamental Theology is a classic text by the late Fr. Joseph Clifford Fenton, a highly respected author, professor, and theologian of the twentieth century. “This book appeared in 1942 under the rather unimposing title We Stand with Christ: an Essay in Catholic Apologetics. It should have become a classic. It is, I believe, the greatest work of apologetics produced in a time of superstar apologists such as F. J. Sheed, Ronald Knox, and Fulton Sheen. It represents the high point of apologetics as well as a gold standard for subsequent works of fundamental theology.”—from the foreword by Scott Hahn, Franciscan University of Steubenville.

Isaac Thomas Hecker (December 18, 1819 - December 22, 1888) was an American Roman Catholic Priest and founder of the Paulist Fathers, a North American religious society of men; he is named a Servant of God by the Catholic Church. Hecker was originally ordained a Redemptorist priest in 1849. Then, with the blessing of Pope Pius IX, he founded the Missionary Society of St. Paul the Apostle, now known as the Paulist Fathers, in New York on July 7, 1858. The Society was established to evangelize both believers and non-believers in order to convert America to the Catholic Church. Father Hecker sought to evangelize Americans using the popular means of his day, primarily preaching, the public lecture circuit, and the printing press. One of his more enduring publications is The Catholic World, which he created in 1865. Hecker's spirituality centered largely on cultivating the action of the Holy Spirit within the soul as well as the necessity of being attuned to how He prompts one in great and small moments in life. Hecker believed that the Catholic faith and American culture were not opposed, but could be reconciled. The ideas of individual freedom, community, service, and authority were fundamental to Hecker when conceiving of how the Paulists were to be governed and administered. Hecker's work was likened to that of Cardinal John Henry Newman, by the Cardinal himself. Father Hecker's cause for Sainthood was opened January 25, 2008, in the mother Church of the Paulist Fathers on 59th St, New York City.
