A liberal Protestant theologian who challenged orthodox doctrines, championing historical criticism and a modernized view of Christianity's development.
Arthur Cushman McGiffert stood at the storm center of American religious thought at the turn of the 20th century. The son of a Presbyterian minister, he studied in Germany, absorbing the historical-critical methods that would define his career. As a professor at Union Theological Seminary in New York, he became a leading figure of theological modernism. His groundbreaking work, 'A History of Christianity in the Apostolic Age,' argued for a radical diversity in early Christian belief, a view so controversial it led to his resignation from the Presbyterian ministry. Unfazed, he continued to shape liberal Protestantism, later serving as president of Union Seminary. McGiffert's legacy is that of a courageous scholar who insisted that Christian faith could and must engage honestly with modern historical and scientific thought, a stance that permanently altered the landscape of American theology.
