We possess very few written remnants of the time immediately succeeding the Apostles. The writers are St. Clement of Rome, St. Barnabas, Hermas, St. Ignatius of Antioch, St. Polycarp, Papias, and the writer of the letter to Diognetus. With the exception of the “Pastor,” these are all in the form of letters, conveying strong feelings expressed in few words, short and touching exhortations, simple narratives of joys and sorrows. These first Christians were anything but literary; they were only conscious of possessing a divine truth which had incomparable value above all earthly things. Nevertheless it deserves to be remarked, that short as these writings are, we have in them the first outlines of all future learned teaching.[173] In the letter to Diognetus we have a sketch of the course which Christian apology against heathens afterwards took; in the letters of St. Ignatius, the first features of the Church’s defence against heretics; in the letter of Barnabas, an approach to speculative theology; in the “Pastor,” the first attempt at a Christian science of morals; in the letter of Pope St. Clement, the first development of the government which afterwards produced the Canon Law; and in the Acts of St. Ignatius’ martyrdom, the earliest historical production. In these, as it were, infantine movements of His first disciples, the Divine Child was manifesting the future conquests which He would achieve in leading His people through the whole range of the divine science.
In the second century the Church vastly increased in the number of her faithful and in her influence; at the same time she was exposed to much severer attacks from within and without. Through the whole century the false Gnosis afflicted her. The Greek and the Oriental philosophy had fully detected the presence of a great enemy, and fought against her with all the arms of learning, the brilliance of Eastern imagination, the fire of religious zeal. It is said that in the first fifteen hundred years no sect has pushed the Church more hardly than Gnosticism, which through the brilliant talent of its leaders in Alexandria, Antioch, Edessa, and other great cities gained many adherents. The attacks from the heathen and the defacements which Christian doctrine received through heretics formed thus the strongest challenge to Christians to defend themselves with the arms of learning and science on their own side.
There were great difficulties in the way. The mass of Christians was still drawn from the lower ranks, and was accordingly unlettered. All, too, that were of higher rank had no other than the heathen schools to frequent, and were thus in great danger themselves from the force of heathen culture. A remarkable result ensued: for, one after another, champions of the Christian cause arose from among the heathen themselves who were converted to the Christian faith. Justin, we are told, sought for truth about the being of God and the soul’s immortality in the schools of the Greek philosophy. He tried successively the Stoic, the Peripatetic, the Pythagorean, and the Platonic, and thought that he had found truth in the last; when, in the midst of these dreams, walking out one day in a lonely place by the sea-shore, he met with an old man with whom he entered into conversation. This man, pointing out the futility of his past search, directed him to the Christian teaching. Justin says that he felt a fire in his heart kindled by the old man’s words; he followed his advice, and found here what he had in vain sought elsewhere—the only true philosophy. He became a Christian in middle age, dedicated his life to propagate the faith which he had embraced, and died a martyr for it.
His pupil, Tatian, seems to repeat this history. An Assyrian by birth, he was instructed in all branches of Grecian literature, and had tried every shade of the old heathen wisdom. But the corruption of the heathen world inspired him with abhorrence; he was converted by Justin, and found in the Christian doctrine the ideal which he sought. Yet afterwards certain rigorous views led him into error, and he became the head of a Gnostic sect.
Athenagoras of Athens supplies us with another like conversion. He was an adept in the Greek, especially the Platonic philosophy, and was devoted to heathendom. With the intention of writing against Christians he studied the Holy Scriptures, and in doing so was converted. He has left us two brilliant writings, one an apology in defence of Christians, addressed to the Emperor Marcus Aurelius, and another setting forth the doctrine of the resurrection with admirable skill.
Theophilus of Antioch continues the list of converts. The study of the Holy Scripture led him to become a Christian, and he afterwards rose to the great See of Antioch, and has left learned writings in defence of the faith.
More brilliant than all these, the first as well as the greatest Latin writer in the West of the whole ante-nicene period, Tertullian, born of heathen parents, studied philosophy and literature, was converted about the age of thirty, became a priest, and dedicated himself by word and writing to the defence of the faith. Every subsequent age has admired the force of his reason. It amounted to genius, yet a rigoristic spirit led him to fall off to a sect.
Pantænus, who became head of the catechetical school at Alexandria about 180, had been a Stoic. His conversion repeats that of Justin. A man of the highest renown for his Grecian learning, he became equally distinguished as a Christian. He devoted himself to preaching. He was also noted as the first who not only commented by word of mouth on the Sacred Scriptures, but wrote his commentaries against Gnostic commentators of the day. For it is remarkable that, in their zeal to get the Scriptures on their side, the Gnostics had preceded the Christians in the explanation of Scripture, which they treated with the utmost latitude of private judgment.
Still more distinguished was Clemens, the pupil as well as the successor of Pantænus. Born about the middle of the second century at Alexandria or Athens, and endowed with great ability, he searched all the systems of Greek philosophy. He was full of learning when grace made him a Christian, and from that time he devoted all his powers to deepen his knowledge of the Christian faith, and to convey that knowledge to others, by drawing out a true Gnosis against the false, a main seat of which was at Alexandria, over the school of which he presided.
I have taken the seven great converts, Justin, Tatian, Athenagoras, Theophilus, Tertullian, Pantænus, Clemens, who all became apologists of the Church after their conversion, as specimens of the power which she exercised in the second century of drawing the higher spirits among the heathen into her fold. That power did not diminish but increase in the third century. It exerted itself with great effect through the establishment in the course of the second century of a system of learned instruction in the great catechetical schools. The chief of these was at Alexandria; for where the munificence of the Ptolemies had planted and richly endowed a seat of Greek learning, science, and philosophy, which had been enlarged by Tiberius, so that youth thronged to it from all parts of the Roman Empire, now the Christian Church, which probably from its beginning had there the usual school for instruction of catechumens, by degrees enlarged the instruction given in that school, and introduced learned lectures upon the Christian faith. Before long a complete learned education, all that we mean by an university, was set up. The object was not only to instruct Christian youths, but likewise to attract cultured heathen, especially the young, to prepare them gradually, and gain them to the Christian faith. Explanation of the Sacred Scriptures formed the chief point, but likewise grammar, rhetoric, geometry, and philosophy were studied. The exact point of time when all this took effect cannot be assigned; it is probable that it took time to perfect the system. Athenagoras is the first named president, who was followed from the year 170 to 312 by Pantænus, Clemens, Origen, Heraclas, Dionysius, Pierius, Theognostus, Serapion, Peter the Martyr. Each of these had fellow-workers under him, who increased in number as time went on. A crowd of learned men, bishops, saints, and martyrs, came out of this school. The envy and hatred of the heathens were so incited by it, that they often surrounded the house with soldiers, seized upon students, and led them away to execution. The renown of the school was so great in the middle of the third century, that Anatolius, a pupil of it, was sought by the heathen themselves to succeed Aristoteles in the headship of the Alexandrian university.
