One prelate who refused to fall for this tactic was the American Jesuit Msgr. Joseph C. Fenton. Fenton (d. 1969), a priest of the diocese of Springfield, Massachusetts, was professor of fundamental dogmatic theology at the Catholic University of America and editor of the American Ecclesiastical Review for twenty years (1943–1963). He is considered one of the most outstanding American Catholic theologians of the 20th century, serving as a peritus for Cardinal Ottaviani at Vatican II. He was also Secretary of the Catholic Theological Society of America and was an indomitable foe of Modernism. The pre-Conciliar popes heaped honors upon Msgr. Fenton: The Holy See named him a papal chamberlain(1951), a domestic prelate (1954), and a protonotary apostolic (1963). Recipient of the papal medal, Pro Ecclesia et Pontifice (1954), he belonged to the Pontifical Roman Theological Academy and served as a counselor to the Sacred Congregation of Seminaries and Universities (1950–67). He was also known for his virulent opposition to the teachings of John Courtney Murray, S.J. on the separation of Church and State.
Fenton was no lightweight, and he recognized the false dichotomy for what it was. Rejecting the notion of Modernism and integralism as two opposite extremes, he attempted to bring some sanity back to the discussion by noting that integralism was essentially just Catholicism:
"[The inattentive Catholic] might possibly come to the dangerously false conclusion that modernism and integralism, as we know them, are two contrary false doctrines, one, as it were to the left, and the other to the right, of genuine Catholic teaching. Nothing, of course, could be farther from the truth. Modernism, in the technical language of Catholic doctrine, is the name applied to the definite series of errors condemned in the decree Lamentabili sane exitu, the encyclical Pascendi dominici gregis, and in the motu proprio Sacra antistitum. Pope Pius X spoke of Modernism as the "conglomeration of all heresies."
Integralism, on the other hand, is essentially the teaching or the attitude of those who worked for the presentation of an integral Catholicism, of Catholic dogma set forth accurately and in its entirety. Most frequently the name of integralism was applied to the doctrine and the viewpoint of those Catholic writers who entered into controversy against the modernists during the first decade of the present century. Understood in this fashion, integralism was nothing else than the contradiction of heretical modernism. It was thus basically only the exposition of Catholic truth." [10]
Thus, integralism is "basically only the exposition of Catholic truth." In other words, integralism is another word for an approach to Catholicism that is harmonious and unified across all fields of human activity; it is Catholicism applied.
