Preliminary Remarks: Patristic Philosophy

The emergence of Christian philosophy: the encounter of Revelation with Greek thought, the role of the Fathers, and the challenge of heretical systems to orthodox doctrine.

Patristic philosophy is the philosophical reflection of the Christian Fathers — the great theologians and apologists of the 1st through 5th centuries — as they sought to articulate, defend, and deepen the faith in dialogue with the philosophical traditions of the pagan world. Its governing conviction is the harmony of faith and reason: natural reason is capable of genuine philosophical truth and is not destroyed but elevated and completed by faith; Greek philosophy, at its best, is a 'preparation for the Gospel' (praeparatio evangelica). The Fathers drew selectively and critically on Greek philosophy — chiefly Platonism and Stoicism — using its conceptual resources to express the content of revelation while purifying its errors. The principal philosophical achievements of the Patristic period are: the doctrine of creation ex nihilo (against emanationism), illuminationist epistemology (Augustine), and the philosophical theology of the Trinity and the Incarnation.

PRELIMINARY REMARKS Philosophy is a continuous growth until it has reached the perfection of maturity. New systems of philosophy are, therefore, never wholly new; they are built upon the achievements of the past. The philosophy of pagan times furnishes the foundation upon which the philosophical systems of Christian times were built. Now the coming of the Religion of Jesus Christ was a tremendous occurrence in the world of thought. Upon all philosophies it had an enormous influence; in many it was a revolution. Christianity, while contributing immeasurably to the development of the true philosophy by reason of the new and steady light which it threw upon the pathway of the earnest thinker, was set for the fall of many philosophies, just as its Divine Founder was set for the fall of many in Israel. Its coming marked the time for men and minds to get in line with truth. That many have refused to hear the summons of the time—and still refuse—is only an evidence of a truth too obvious to need special evidence : that man has free-will, and is often wilful; in the good and bad sense the advent of Christianity showed that man has a will of his own. But just as sincere pagans groped for truth before the coming of Our Lord and His deathless Church, so pagan philosophies groped for truth. Pagans and pagan philosophies had sometimes come near to truth, had sometimes grasped it in part. Now that Christ had come, the sincere pagan had need to grope no 141 longer, for the fullness of religious truth came to him and offered him its certitude, and he was no longer a pagan when he accepted it. And sincere pagan philosophy, freed from the baffling questions of origins in the world and of purpose in human life—things inevitably bound up with religion— was moved by a powerful influence of development, and began a steady growth towards maturity. Henceforth philosophy was to have a guide in the certainty of religious knowledge, a guide of which true philosophy took immediate advantage, but which false philosophies refused, as they continue in the present age to refuse, to recognize or employ. In early Christian times some philosophers subordinated the Christian Revelation to pagan science, and these developed heretical systems of philosophy. Other Christians made proper use of their philosophic heritage, and employed its principles as the basis of their expositions of revealed truth. These orthodox writers are called “Fathers of the Church.” The Fathers are theologians rather than philosophers, yet, for two reasons, some of them must be given a place in the History of Philosophy. First, these men made an earnest study of philosophy to equip themselves for the task of controverting such heresies as had a philosophic cast. The Fathers whose chief effort was the refutation of heresy by a clear exposition of the reasonableness of Christian Faith are known in religious history as “Apologists.” Again, the Fathers cultivated philosophy that they might use it as a scientific instrument in the investigation and elaboration of revealed truth. Thus many of the Fathers of the Church were true philosophers, philosophers whose influence upon contemporary and subsequent thought was far from negligible. We include, therefore, the more notable of these theologian-philosophers in the History of Philosophy. The first Chapter of the present Book deals with the heretical systems of philosophy, or rather the heretical religious systems of a philosophical character; and with the Fathers (Apologists) whose work was the refutation of heresy. The second Chapter treats of those Fathers who made positive and constructive advance in the development of theology and philosophy. Because the more notable of the philosophers here discussed were Fathers {Patres} of the Church, the present Book is called a history of Patristic philosophy. The Chapters to follow are: Chapter I. Heretical Systems and the Apologists Chapter II. Constructive Patristic Philosophers HERETICAL SYSTEMS AND THE APOLOGISTS (1-325 A. D.) The heretical philosophies against which the Apologists of the first three centuries waged intellectual warfare were, above others, Gnosticism and Manicheism. There were other and, in some cases, larger heresies than these in the early days of the Faith, but the two mentioned deserve notice in a History of Philosophy because they were philosophies as well as heresies ; the others have a prominent place in the History of the Catholic Religion, but need not be mentioned here. The Fathers or Apologists of this period (1-325) are often called “The Ante-Nicene Fathers” because they lived and worked before the momentous Council of Nicæa or Nice (in Asia Minor) which took place in the year 325. This was the first General or Oecumenical Council of the Church; and its canons or decisions definitely settled much that was open to free discussion during the days of the Apologists here considered. We divide this Chapter into three articles: Article I. Gnosticism Article 2. Manicheism Article 3. The Ante-Nicene Apologists Article i. Gnosticism
