Summary View of the Pre-existence and Divinity of Our Saviour and Lord Jesus Christ
17 But why the Gospel was not preached in ancient times to all men and to all nations, as it is now, will appear from the following considerations. The life of the ancients was not of such a kind as to permit them to receive the all-wise and all-virtuous teaching of Christ.
18. For immediately in the beginning, after his original life of blessedness, the first man despised the command of God, and fell into this mortal and perishable state, and exchanged his former divinely inspired luxury for this curse-laden earth. His descendants having filled our earth, showed themselves much worse, with the exception of one here and there, and entered upon a certain brutal and insupportable mode of life.
19. They thought neither of city nor state, neither of arts nor sciences. They were ignorant even of the name of laws and of justice, of virtue and of philosophy. As nomads, they passed their lives in deserts, like wild and fierce beasts, destroying, by an excess of voluntary wickedness, the natural reason of man, and the seeds of thought and of culture implanted in the human soul. They gave themselves wholly over to all kinds of profanity, now seducing one another, now slaying one another, now eating human flesh, and now daring to wage war with the Gods and to undertake those battles of the giants celebrated by all; now planning to fortify earth against heaven, and in the madness of ungoverned pride to prepare an attack upon the very God of all.
20. On account of these things, when they conducted themselves thus, the all-seeing God sent down upon them floods and conflagrations as upon a wild forest spread over the whole earth. He cut them down with continuous famines and plagues, with wars, and with thunderbolts from heaven, as if to check some terrible and obstinate disease of souls with more severe punishments.
21. Then, when the excess of wickedness had overwhelmed nearly all the race, like a deep fit of drunkenness, beclouding and darkening the minds of men, the first-born and first-created wisdom of God, the pre-existent Word himself, induced by his exceeding love for man, appeared to his servants, now in the form of angels, and again to one and another of those ancients who enjoyed the favor of God, in his own person as the saving power of God, not otherwise, however, than in the shape of man, because it was impossible to appear in any other way.
22. And as by them the seeds of piety were sown among a multitude of men and the whole nation, descended from the Hebrews, devoted themselves persistently to the worship of God, he imparted to them through the prophet Moses, as to multitudes still corrupted by their ancient practices, images and symbols of a certain mystic Sabbath and of circumcision, and elements of other spiritual principles, but he did not grant them a complete knowledge of the mysteries themselves.
23. But when their law became celebrated, and, like a sweet odor, was diffused among all men, as a result of their influence the dispositions of the majority of the heathen were softened by the lawgivers and philosophers who arose on every side, and their wild and savage brutality was changed into mildness, so that they enjoyed deep peace, friendship, and social intercourse. Then, finally, at the time of the origin of the Roman Empire, there appeared again to all men and nations throughout the world, who had been, as it were, previously assisted, and were now fitted to receive the knowledge of the Father, that same teacher of virtue, the minister of the Father in all good things, the divine and heavenly Word of God, in a human body not at all differing in substance from our own. He did and suffered the things which had been prophesied. For it had been foretold that one who was at the same time man and God should come and dwell in the world, should perform wonderful works, and should show himself a teacher to all nations of the piety of the Father. The marvelous nature of his birth, and his new teaching, and his wonderful works had also been foretold; so likewise the manner of his death, his resurrection from the dead, and, finally, his divine ascension into heaven.
24. For instance, Daniel the prophet, under the influence of the divine Spirit, seeing his kingdom at the end of time, was inspired thus to describe the divine vision in language fitted to human comprehension: “For I beheld,” he says, “until thrones were placed, and the Ancient of Days did sit, whose garment was white as snow and the hair of his head like pure wool; his throne was a flame of fire and his wheels burning fire. A river of fire flowed before him. Thousand thousands ministered unto him, and ten thousand times ten thousand stood before him. He appointed judgment, and the books were opened.”
25. And again, “I saw,” says he, “and behold, one like the Son of man came with the clouds of heaven, and he hastened unto the Ancient of Days and was brought into his presence, and there was given him the dominion and the glory and the kingdom; and all peoples, tribes, and tongues serve him. His dominion is an everlasting dominion which shall not pass away, and his kingdom shall not be destroyed.”
26. It is clear that these words can refer to no one else than to our Saviour, the God Word who was in the beginning with God, and who was called the Son of man because of his final appearance in the flesh.
27. But since we have collected in separate books the selections from the prophets which relate to our Saviour Jesus Christ, and have arranged in a more logical form those things which have been revealed concerning him, what has been said will suffice for the present.
